Save Lee
An APP for mprove user’s sleep
Group work
mary research & ana ysis, Prototype, User test
Co aborative pro ect between Loughborough Un versity and GenGame energy company, which aims to improve the user exper ence whi e using smart meter data to reduce the negative mpact of home energy consumption.
Save Lee s an APP focuses on improv ng users' sleep by help ng them to reduce emotiona stress before bed so that they can fa l asleep as quickly as poss ble while reduc ng the r home energy consumption.

BRIEF
BACKGROUND
Current energy problems
Energy consumpt on from electr cal appl ances in da y l fe generates large amounts of carbon em ssions wh ch generate tons of ‘greenhouse’ gases and ead to many problems in the natura environment such as c mate change.
22% Tota Carbon Em ss 22% is from ho 30% Resident Carbon Em 30% is hou appliance
Smart meter in UK family
Every UK home w nsta a 'smart meter’, wh ch cou d he p consumers monitor their energy use to save more money less energy consumptionw th .
By
•Use histor c data to forecast energy consumption
•Disaggregate energy used E.g. 24% wash ng,9%Lighting ...
So what else we can do...
How m ght we des gn a mob e app that uti ses smart meter data to reduce the negative impact of domest c energy consumpt on?
DEFINE THE PROBLEM with 5W1H
Initial Problem Statement
1How might we des gn a mobi e app that ut ses smart meter data to encourage [ students who ves n Student Ha ls, pay attention to their health problems and want to have a better living environment ( comfort temperature, humid ty, brightness and a r quality ) ] to [ use e ectrica appliances in an appropriate way to reduce energy consuming ].
2How m ght we design a mob le app that uti ses smart meter data to encourage [ students who ives in Student Halls, have a higher awareness of energy saving and environmenta protect on and ove sharing moments ] to [ compete and share how much energy they save w th others to use less energy].
The user base is too small for the ssue to be general and inuential and therefore not considered

USER RESEARCH nterv ew 7 part c pants target user g oup
Interv ews with the target group were conducted to test the nitial p r o b l e m a s s u m p t i o n . T h e i n t e r v e w q u e s t o n s r e v o v e d around hea th knowledge, v ews and behav ours, with questions on health behav ours inc ud ng s eep, d et, exerc se, sk n, hair, body, env ronment and menta .
DATAANALYSIS
Participant Boards
The mportant informat on from the 7 part c pants’(what they say/do) nterview transcr ptions was extracted, coded and col ated on post it notes. The three categories of health ssues that were most mportant to each participant were summarised and it was seen that sleep was the most important to part cipants, fo owed by d et.
DATAANALYSIS
Extract the key insights
From ndings, nsights re at ng to patterns, unusua informat on were dent ed and eva uated by2×2 matrix with two d mens ons and'desirabi ty for users' potential for energy savings fourto extract the key nsights. Finally, the sweet spot contains the key nsights' with the h ghest strengths n both dimensions.
REFINED PROBLEM STATEMENT
By analys ng the data from the primary research, we rened the in t a prob em assumption.
How m ght we des gn an app that util ses smart meter data to encourage [students who pay attention to the r health and want to have a better living environment] to [use e ectrical appl ances n an appropriate way to reduce energy consum ng].
Afnity Diagramming
The coded sticky note of a part c pants n the Part c pant board(what they say/do) were summar sed and organ sed n a ogical way as an Afnity Diagram for qua tative analys s.Common ssues and mportant or spec a nformation from the part cipants were summarised as . and formed the wh ch'nding' what it means 'why it matters nsights' explained and showed how t nuenced the theme of energy consumpt on''nding'

Painpoints
ŸWant to develop the habit of going to bed ear y but always fai
ŸOften suffers from nsomn a due to stress
Scenario
When: It’s eleven o c ock at n ght in w nter n UK Where: Her pr vate room n student ha l
X ao Lee is studying and was absorbed in thinking about the knowledge. The qu et env ronment and difcult knowledge made her forget the t me. Time passed quickly, and soon the t me come to eleven o c ock.
Story board - Bu d ng user ourney for 3 key features based on persona and scenar o
Xiao Lee was study ng at night. Difcu t know edge made her forget the time.
Sooth ng music p ayed, t was the APP rem nded her it was time to go to bed.
Decided to fo ow app s adv ce to go to bed and puts on wearab e device.
After stay ng n bed, She was st ll th nking about study, can’t fal as eep.
Wearable dev ce detected her st ll awake, phone ght up to ask f she needs s eep a d.
EXPERIENCE PROTOTYPING
Body storming Two rounds
We performed the user journey with the sett ngs n storyboard and recorded it through video to identify issues in the key journeys and rev se them
Chose type of sleep a d, APP played persona ised aud o automat ca ly.
Didn’t ke t, and c cked "Change style" (optim sat on through data )
Th s audio was su tab e for her.Re axed and fa s asleep gradua ly.
Morn ng, checked her mood changes during s eep aid, t me took to fall as eep and found it rea y he p.
Found her s ept 2 hours ear er, save more energy, the v rtua character ‘Lee’ grows more ha r n APP. She fe t mot vated.
Round 1 Revised details
• mprove rem nder methods of our App and wristband;
• Add dark theme to some pages n our App;
• Add audio auto off function after user fa s as eep n our App;
Round 2 Revised deta
• Optimise the reminder funct on of our app and wristband
• Improve the data udgment of the dev ce to get accurate data recording

EXPERIENCE FLOW CHART
By exper ence prototyp ng and ssue revisions, we sorted out the experience ow. n the follow ng chart we have covered a l the possibil t es of user behaviour interact ng w th the functional details of the app during the comp ete ma n user journey.
Page information structure
User ow
Analiysis Page Prob emat c, needs further renement testing
Users can v ew the previous n ght s sleep data and trends n bedtime changes on the "Analys s & Feedback" page, the change n virtua mage: ‘Lee’ and a so v ew the n ght y energy data records to v sua y see the energy saved by going to bed ear y last n ght, and to v sual y see the trend of reduced energy consumpt on as they gradua ly develop an ear y bedtime routine. Users wil be more motivated to go to bed early.
Unreso veled Issues in Analiys s Page
The data integrat on and arrangement of the Analys s and Feedback page s confusing and acks sufcient prior ty og c. The s gn cance of ana ys s data for users n the experience shou d be strengthened through subsequent user testing and changed to a more reasonable arrangement.
GENERATE LO-FI PROTOTYPE FOR TESTING- After sorting out the functiona hierarchy of pages n the main user ourney, the user ow and ts corresponding wireframes were constructed

USER TEST METHOD
Low delity prototyping
Using observation and semi-structured interviews
Test ng on one target user using wireframes v a marve . To create the most rea istic user experience,The test s te was set at the user s home.The time background s mu ated n the test was the bedtime per od, and the next morn ng per od, and simulating the bedt me rem nd ng behav or, the s eep aid behavior, and the behavior of v ew ng the previous n ght's data, respective y.
Main issues explored in the test
The rat ona ty of page interact ons.
ŸReasonab eness of the og cal hierarchy between pages.
ŸThe rat ona ty of the nformation ayout and c ass cat on, the comprehens veness of the nformation of the ‘Analysis and feedback’ page.
USER TEST RESULT & ITERATION
1. User think Lee's is not easy to notice, so Lee was moved to a new page
2. User th nk that the nformation about sleep time should be clear and obvious , so the goa and actua s eep time modu es were added above, also the trend graph of sleep t me with n a week s added to reect the recent y sleep ng pattern n Ana ysis and Feedback' page
3. Energy and sleep were two d fferent categor es, so a hor zontal cut-screen interaction was used to separate the two categor es n the Ana ys s and Feedback page
Changes in layouts & interaction Changes in how to use smart meter data
The mpact of encourag ng users to sleep early by only "energy sav ngs per night" and ‘the using trend’ s not obv ous enough, so adding the modu e of " energy savings accumulation from the beginn ng date" to g ve users a deeper impression.
