INTRODUCTION The product I have been aiming to develop is one that benefits a wide range of users. People who are both young and old and who have different levels of fitness will benefit from the system. One of the things that these users may be missing is the motivation to keep active and to keep up momentum after short bouts of health kicks. Not everyone has the will of a personal trainer inside them or can afford to hire one everyday - but what if you could have one in your pocket and on your wrist? Would you be more motivated? The reason to try and increase motivation to be physically active in Australia is clear, we as a nation are at risk of becoming one of the most overweight nations on the planet. Being obese and overweight increases the risk of diabetes and serious heart conditions, which can trigger other health related issues that will continue to be a problem later on in life. Not only will these issues continue to plague people in 6

the community but they will also put more pressure on our already over stretched health care system in years to come. The Body Watch system will help users to become more physically active and sustain this level of activity for a longer period of time. It will allow them to enter the later periods of their life better set up in terms of their health. It will be a preventative measure against issues that occur from being inactive, such as heart disease, one of the leading causes of death in Australia. Body Watch will be used to help motivate the individual to keep active and keep track of their activities. Keeping an individual motivated is a key part of the product because if youâ&#x20AC;&#x2122;re more motivated and challenged you are more likely to continue to enjoy being active.

THE PROBLEM

AGEING POPULATION

Between now and 2050 the number of people aged 65 to 84 is expected to more than double. However, the number of people over 85 will quadruple from around 0.40 million to a massive 1.8 million. Both these groups combined will take up over 25% of the population in Australia alone. The issue with this is that the Australian health care system is already over stretched and the waiting lists for people to enter aged care is growing. As the population gets older there will also be an increased number of cases of heart disease, obesity, diabetes, depression and people suffering the effects of arthritis.

2050

CARDIOVASCULAR DISEASE In 2008 there were over 600,000 (Australian Institute of Health and Wellbeing, 2008) people who were diagnosed with coronary heart disease and from this there were over 150,000 hospitalisations (AIHW, 2008) and 22,729 deaths (AIHW, 2008) just from Coronary Heart Disease. Altogether cardiovascular diseases affect 3,395,873 it hospitalises 475,122 and kills 46,626 (ABS 2007-08). Causes of cardiovascular disease

To reduce your risk and aid your recovery: •Be smoke-free •Enjoy healthy eating •Be physically active •Control your blood pressure and cholesterol •Achieve and maintain a healthy body weight •Maintain your psychological and social health.

•Smoking - both active smoking and being exposed to second-hand smoke •High blood cholesterol •High blood pressure •Diabetes •Physical inactivity •Being overweight •Depression, social isolation and a lack of social support.

OVER WEIGHT & OBESE Results from a survey conducted by the Australian Bureau of Statistics reveal that in 2007-08, 61.4% of the Australian population is either overweight or obese (Australian Bureau of Statistics 2008). Now if we look at older Australians we can see that as the population gets older a greater percentage of them are overweight. In 2007-08, 39.9% of males between the ages of 55-64, 45.1% of males between the ages of 65-74 and 52.8% of males aged 75 years and over, were classified as overweight while 35%, 33.9% and 21.5% respectively, were classified as obese (ABS, 2008). For females, 34.6% between the ages of 55-64, 42% between the ages of 6574 and 31.8% aged 75 years and over, were classified as overweight, while 33.4%, 29.4% and 25.1 % respectively, were classified as obese (ABS, 2008).

THE PROBLEM

ARTHRITIS & EXERCISE There have been studies done that suggest that continued exercise throughout our lives and into our elderly years can help and also prevent the onset of certain diseases and conditions. One of these conditions that can benefit from exercise is arthritis. Exercise cannot only help prevent the severity arthritis later in life but also help to ease the effects once it has affected the joints. Arthritis is the inflammation of one or more of your joints. The main symptoms are pain and stiffness in the joint and these will most often worsen with age. There are two main types of arthritis, osteoarthritis and rheumatoid arthritis. Osteoarthritis is caused by the general wear and tear of the joint over time. Rheumatoid arthritis is due to an autoimmune disease, which breaks down the cartilage in the joint revealing the bare bone. So how will exercise prevent arthritis? The issue is that if we have 16

THE PROBLEM

a sedentary lifestyle as many people do later in their lives, the muscles around joints begin to waste away. The strength the joints once had will start to decline, allowing things to slip and roll more easily and sometimes result in the damage of tendons and ligaments. Exercise also helps to keep the joints flexible and stops the cartilage in joints stiffening and causing pain when they are used. Exercise will help keep weight down and alleviate the added stress that weight might have on the joints. It has been suggested that those most likely to have arthritis are people who have low cardio vascular fitness. Physical activity creates lubricant over the cartilage and prevents stiffness and pain.

AUDIENCE

ELDERLY The subjects I interviewed although having a variety of different issues specific to them, all had a few key things in common. Most of the subjects said they had a lot of joint issues, these where mainly affecting their backs, legs and also their fingers. The fingers it seemed was one of their greatest perceived problems as they often found it difficult to do simple tasks such as doing up a button or using cooking utensils. Other problems they raised were that they didnâ&#x20AC;&#x2122;t feel safe going into the garden due to uneven surfaces; the threat of becoming unbalanced when working in garden beds and doing overhead work. Some of the subjects had already had falls, which had resulted in two cases of having a broken hip. They said that this event had made them extra cautious. Many of the issues that elderly people face can be prevented, however in order to do this preventative 20

AUDIENCE

measures need to be taken in the earlier years of their life. Hence I created a solution that could be introduced earlier in life and develop life long behaviour change that would help to generate a better quality of life in future years.

STAKE HOLDERS For my system to be effective, the stakeholders have been identified and broken up into three sections. 1. Support Support is needed in order to help the user reach their maximum potential. Friends and family can give this support however the Body Watch system allows the individual to gain knowledge from experts such as doctors, nutritionists and personal trainers. 2. Private sector. Large Australian organisations and companies can assist in creating a healthy more active population, as many of these companiesâ&#x20AC;&#x2122; key philosophies revolve around a concept of healthy living. 3. Government Financial support from government and council groups is essential to

enable companies such as YMCA, Coles and Woolworths to continue to run profitable businesses. Hopefully in thxe future Body Watch can ease the pressure on government run oganisations such as hospitals, Medicare and medical centres.

MOTIVATION

Education is an important part of motivating anyone. It empowers them to take a more informed and active roll in their own health. It can also help to correct the misconception that illness and injury are caused by activity when really it can improve some illnesses. By educating people you can provide alternatives and improve their mental outlook on exercise.

SOCIAL Organised forms of physical activity provided a social setting that is a key motivational factor. People are more likely to be active if there is a social factor. It is particularly important for those who may be living alone and feel isolated from the outside world. By being social it will not only help their performance but also their mental health.

GOALS Any program promoting exercise should involve a goal and also a reward. Being able to achieve and reach a goal enables a more pleasant and â&#x20AC;&#x2DC;confidence inspiringâ&#x20AC;&#x2122; experience for the user. If a user is able to achieve the allotted amount of physical activity for a specfied day, then they will be rewarded for their efforts. This reward will be their incentive to continue so that they make the activity a daily habit.

POSITIVE REINFORCEMENT Positive reinforcement is a simple concept to grasp. Reinforcement occurs when a reward, sometimes called a reinforcer, is given for a specific desired behaviour. Other behaviours, even those that are negative, are simply ignored. Over time, this will lead to an increase in the desired behaviour. Positive reinforcement must be individualised to the specific person receiving it. What reinforces one personâ&#x20AC;&#x2122;s behaviour may not have the same effect on someone else (Fritscher). The problem is that with exercise the rewards of your work arenâ&#x20AC;&#x2122;t always seen straight away it can take a long time before any change is noticeable. This can cause people to relapse into their old behaviour and not continue with their routine. This is why providing a reward that is tangible and can be seen straight away is important in continuing the activity levels of an individual.

MOTIVATION

One of the most powerful methods of positive reinforcement is variable ratio schedule (Lickerman). This is where the reward is not always the same so you try and see if you can get a different result the next time. It makes your mind want to replicate the results of previous reinforcement so you continue to try. Positive reinforcement can be a very effective tool in promoting a behaviour. Much like training an animal, for instance when a dog does something right we reward them to let them know that what they just did was positive. But eventually that behaviour will become part of the dog and they will no longer need the reinforcer to do that same act. This principle is also the same for us. We may need to be encourged at the start with rewards but once we begin to see the results later on, we then realise that we no longer need that extra little reward in order to keep motivated.

POSITIVE

REINFORCEMENT

SOCIAL MOTIVATION Social motivation is the incentive or drive resulting from sociocultural influences that initiate behaviour towards a particular goal (Elsvier). Nearly everything we do and the way we behave is motivated behaviour, which has an end goal. These behaviours and judgments are heavily influenced and motivated by societyâ&#x20AC;&#x2122;s view. There are two types of social motivation, conscious and unconscious. Unconscious motivation is carried out almost automatically and results in the person being unaware that their behaviour is being influenced by society norms. When people are asked about this behaviour they often come up with the incorrect justification for why they are doing it because it is so ingrained in their psychological make up (Forgas). Social motivation can play a huge role in exercise motivation not only from social support but also creating a social pressure on the participant. If a person engages with others during an exercise program they will feel 30

MOTIVATION

the pressure of this social group. If the group is going to meet on a certain day every week and most of the participants are expected to be there then this will motivate the participants to join in the activity on that given day. Also telling people about how you are exercising will help to motivate you more as many of us would not want to be judged for dropping out of an exercise program.

Another social motivation theory is the Theory of Drive. People will be motivated to perform an action in order to meet internal tension caused by unmet needs. For instance this may be something like being motivated to drink a glass of water in order to meet the need of being thirsty. In terms of exercise this theory can be explained by how in order to meet the need of running in a competition wanting to finish, you would most likely meet this need by doing training and going to the gym (Cherry).

HOW TO MEASURE ACTIVITY

AUSTRALIAN EXERCISE GUIDELINES

150 PerWeek

General Recommendations

Intensity

To achieve health benefits, healthy adults should complete a minimum of 150 minutes of moderate intensity cardiovascular exercise or 75 minutes of vigorous cardiovascular exercise per week.

Monitoring cardiovascular exercise intensity helps to ensure the exercise is both safe and effective. It is a critical component of program design. Exercise Professionals can use the following methods to successfully gauge and monitor cardiovascular exercise intensity.

Greater activity levels are associated with further health benefits. Cardiovascular exercise can be accumulated in short bouts of 10 minutes to obtain health benefits. In order to meet the recommended weekly cardiovascular exercise volume, content can consist of a mixture of both vigorous and moderate intensity. One minute of vigorous-intensity exercise is approximately the equivalent of 2 minutes of moderateintensity exercise.

THE CONCEPT

After completing extensive research the concept created is a two-part system, which consists of a smart phone app as well as a device that will constantly monitor the heart rate of the user. Information gathered from the wrist device will be transferred to the app. The information collected allows the user to see their progress and tailor their workouts to their desired result. Unlike other current products on the market, Body Watch will show actual workout intensities and give more accurate data about the level of the userâ&#x20AC;&#x2122;s fitness.

CONCEPT

REFINEMENT

When it came to the refinement of my design I decided to continue further with concepts 2 and 4. Concept 2 This device has a more conventional feel and resembles a digital watch in some aspects. Concept 4 This concept has a more modern design with less information displayed but the form and aesthetics seem to work better with the direction in which I want the product to head. The process I used to refine my design was to create rough physical prototypes and then transfer these forms into a computer environment.

PHYSICAL PROTOTYPING

I began physical prototyping using foam models to create basic forms and to understand the general shape and feel on the wrist. Here are a few examples of the process I went through when creating shapes that I would then attach to my wrist to get a good feel for them.

54 P H Y S I C A L P R O T O T Y P I N G

During the mockup process I went through a lot of iterations of what I wanted to produce. In order to create the smooth organic forms I started off by using Das. This is a form of air-dry clay, however itâ&#x20AC;&#x2122;s very hard to model and takes a while to dry. These 2 designs were the beginning of the direction I wanted to head in producing a smooth form band.

56 P H Y S I C A L P R O T O T Y P I N G

A concept I wanted to extend was that of creating a device that still looked slightly like watches we use today. In these mockups I was looking at how the rectangular form would fit on the wrist. These designs unlike many of the others, featured screens so they needed to be rather large in order to display the information.

58 P H Y S I C A L P R O T O T Y P I N G

In order to create accurate models that would form around the wrist I decided to create life casts of 2 hands, one male and one female. This allowed me to wrap the modeling clay around the wrist and form the clay into the desired shape. The casts also helped when resizing the CAD models so that they would create the correct size.

PHYSICAL PROTOTYPING

These forms were created using modeling clay that had been molded around the life cast hands. These gave a more accurate size and wrist shape that could then be transferred into a CAD environment. The process involved slicing up the models and copying the profile of each section into Solid Works to reproduce the model. A number of these forms where taken further and turned into CAD models and 3D printed to further refine the details.

62 P H Y S I C A L P R O T O T Y P I N G

COMPUTER AIDED DESIGN After modelling up a wide variety of forms I came to a point were I felt I needed to begin to create these shapes in a computer simulated environment. This meant I could create finer more accurate detail which would allow me to generate 3D printed parts. From these parts I would be able to get a better appreication for the size of the product and how the design felt. The computer model needed a lot of fine tuning in order to create the well-resolved design that is the final product.

One of the first CAD generated models 64

CAD DESIGN

These renders show the first attempts at creating the band in a CAD environment. Unfortunately the design was rather blocky and the transitions between the profiles werenâ&#x20AC;&#x2122;t very pleasing. Also after having this design 3D printed I discovered that the scaling was incorrect and out of proportion. After this little (or should I say big) mistake there needed to be a design overhaul. This lead me to create a smoother and more flowing design.

66 C A D D E S I G N

68 C A D D E S I G N

This is one of the final designs before I refined it to create the finished product. Its very similar to the finished product but the form just needed a small amount of modification on the details. From my starting point to this final design there has been a many hanges to the overall aesthetic of the design. It is now more flowing than my original design and although the pod is slightly larger, it doesnâ&#x20AC;&#x2122;t greatly impact on the movements of the wrist.

70 C A D D E S I G N

R E S O LV E D D E S I G N

Reaching the resolved design took a great deal of trial and error. Sixteen different versions of Body Watch were generated until I came to rest on final solution. The form is free flowing and unlike some of my earlier designs the transitions between the different profiles of the band are smooth and joins on to the next section with ease. The pod that sits in the band has a draft angle that widens towards the bottom so that it stays in the band. There is a plug that flares out and also prevents the pod from becoming dislodged. In order to allow for personal taste the podâ&#x20AC;&#x2122;s coloured shell comes in a variety of different colours to match any day wear or gym outfit. Apart from the size of the band this will be the only differing feature of the product from person to person. Another feature of the design is the indicator light situated in the middle of the pod. This light tells the user when they are working too 74

R E S O LV E D D E S I G N

hard or not enough. It can also be programmed to display how much physical activity you have done for the day. 75

1 1. Colour Shell - This section is the coloured part of the pod case. The colour of this part varies from product to product. On its side walls there are indents which the snapfits on the bottom casing clip into. Also it has 3 bosses that help to locate and support the PCB and battery inside the case.

2. Lens – This lens sits in the top colour shell. It has the function of diffusing the light from the LEDs that are in the PCB.

3. PCB – The PCB contains the ‘brains’ of the pod. On its topside it has the LEDs that light up the activity and heart rate indicator. It also has the LED’s that light up the skin behind the pod to evaluate your heart rate. 4. Bottom casing – This section pulls the stucture all together. It has the snap fits that click into the top section as well as the pins that the PCB sits on inside the case. On the back it also has

R E S O LV E D D E S I G N

the charge point, which also acts as a way of securing the pod in the band. 5. The band – The band acts as a way of securing the pod to your wrist. It holds the pod in place with an inward sloping draft angle. There is also a section on the bad that plugs the charge point. This also helps to keep the pod in the band.

THE WRIST POD The Body Watch pod contains all the components that measure your physical activity and send them to your phone. One of the most important features of the pod is the indicator light. The light lets the user know if they are training at the correct heart rate level for what they want to achieve. Red is bad it may mean that user is either pushing there heart rate too high or too low while yellow is somewhere in-between. Green is where the user should aim for when they are exercising. The information gathered from the pod is then sent to the users smart mobile device via Bluetooth.

BODY WATCH APP

BODY WATCH APP The key component of the Body Watch system is the smart device app. The app collects, stores and displays all the information gathered from the wrist pod. The app will instruct the user how to do a Bio Age test as well as show how much activity the user has done during the day, week, month and year. The app also displays live heart rate feed which can offer feedback in terms of what the user wants out of the app. It can also be programmed to display how much physical activity you have done for the day.

BODY WATCH APP

HEART RATE

Not everyone has the same goal when exercising. For some their goal may be to lose wait, for others it might be to increase their aerobic fitness and for some even increase their anaerobic capacity. The Body Watch app can help to train these different heart rate zones. From the Bio Age test the app calculates your maximum heart rate and from here it can determine the different training zones. All the user has to do is to select what type of training they want to do and the app will supply them with a target heart rate. When you select a training zone this information is passed on to the wrist pod and the indicator light will alert the user of when they are training too hard, too light or just right.

BODY WATCH APP

ACTIVITY LEVELS

Being able to monitor activity levels is a great way to track progress as well as keep motivation up. The activity section of the Body Watch app allows the user to track their progress from days to weeks, months and years. Information such as the level of workout intensities is displayed as well as the duration. This allows the user to track their activity levels and see if they are meeting the physical activity guidelines of; 150 minutes of moderate exercise or 75 minutes of vigorous activity per week. This section of the app is a great way to see patterns and trends that may develop, such as a mid week gap where you are very inactive. It displays your progress in terms of your intensities and workouts per week.

BODY WATCH APP

POINTS

A way of motivation is positive reinforcement. If you give something why not get something back? Body Watch allows users to gain points if they reach the Australian fitness guidelines each week. With these points users can get discounts at stores on health foods, on memberships at council run sports centres and also discounts on entering competitions like Around the Bay in a Day bike ride and the Melbourne Marathon. The way users can receive these discounts is to have their phone scanned which displays a QR code (like the image on the left) or to enter their Body Watch membership details when applying for benifits or to enter competitions.

BODY WATCH APP

BIO-AGE

Bio-Age testing is a great feature of the Body Watch app. It allows the user to find out whether their biological age matches their chronological age. Bio-Age testing is designed to test the health and fitness of certain aspects of the body that impact your health and longevity. The way in which people age will differ from person to person. A Bio-Age test gives you an outline of information about your health and fitness and provides inforamtion and feedback which helps make the user motivated to improve their results.

BODY WATCH APP

THE SYSTEM

HOW WILL IT WORK?

Body Watch uses a few different technologies in order to make it function. The Body Watch pod, which monitors the userâ&#x20AC;&#x2122;s heart rate, uses two LEDs and two electro optical sensors to pick up contrast change in the skin when blood is pumped through the body. This information is then sent via a Bluetooth connection to a Smart device running with iOS or Android software. The app then displays all this information for the user to look at and use as an everyday training tool to increase their level of physical activity. The information gathered is also sent to a third party in order to monitor how the subjects are using the product, as well as monitor the reward points and how they are gathered.

REFLECTION

From the research done over first semester, I came to generate certain ideas about how I have shaped my project. I initially began by looking into aiding the current elderly market using technology to give them more freedom and a greater quality of life. However many of the problems that they we’re facing that were stopping them from doing activities they enjoyed where physical issues. Many of the elderly people I talked to had issues with arthritis, joint pain and stiffness. Some also had low bone density, which was the cause of fracturing after having a minor fall. These sorts of issues, which impair quality of life unfortunately, can’t be fixed once they have taken hold. However preventative measures can be made earlier in life to lessen the affects of arthritis, joint pain and even muscle wastage. In order to get a system to work successfully it has to be able provide a few things in order to appeal to 108

the user and keep them motivated. Motivation is one of the most important factors that will either help someone fail or succeed. I identified that in order for motivation to be achieved the user needs to be educated about the issue. They should be enlightened about their situation and how keeping active can help them to live a better life. Next they need to have some sort of goal to strive for, something that they will need to work for but it shouldn’t just be an imaginary goal but actually be something tangible. Semester two was more challenging, as instead of thinking about the service and system, I needed to think bout how the product would work and function within it. The amount of design revisions I went through in order to get to a design I was happy with was huge. If possible, I would continue to keep modifying my design in order to perfect it. However, with the scheduled lead times to

create the prototype I have developed the best design possible. To see the system I had envisaged take shape I needed to learn a few new skills. The first was trying to develop an app that would be able to process and display the information to the user. I spent a lot of my time trying to generate this prototype of the Body Watch app. Going through the Apple developer program and creating licenses for X code and the iPhone I did testing on what was a long and frustrating experience. However I feel that the time I spent on the app has been very worthwhile and successful. It helps the user to create a link between the product I designed and the graphical user interface of the app. Looking back on the year in retrospect, I can see that if I had the chance again I probably would have done things a little differently.Having said this, I’m still very satisfied with

the outcome I have produced, even though I wasn’t able to make the product fully functional due to the technology not being fully developed as yet. Body Watch has the potential to be a remarkable product which could have a huge impact on the quality of people’s lives into their future years.
