RIMAY Smart Communication Wristband

Device that helps low-income deafblind people from rural Peru communicate through text message input in Morse Code

* RIMAY means “Talk” in Quechua , the native language of rural Peru

Research

In a 2015 Peruvian psychology article they estimated...

The problem that then arises is how deafblind people can communicate with friends and family in an accessible and economic way. In Peru there are 14.73 million plans are being used without internet access.

“There are approximatively 15 deafblind people for every 100 000 habitants.”

Description:

The user will select one of three modes depending on what he wants to do.

The first mode turns off the device

The second mode allows the user to select between three previously saved contact numbers. The device will vibrate in Morse code to inform the contact name.

The third mode is where the user can type a message via Morse code and hit send to the contact he previously selected. A haptic feedback will confirm the message was correctly sent.

Three Modes Select Contact Send Message

Dot - Contact 1

Dot / DashType Message

Dash - Contact 2

Triangle - Send Message

Message sent via text message whose use is significantly bigger in rural areas of Peru

Triangle - Contact 3

Ideation

First Prototype: Box Communication Device

Electronic Board designed in EAGLE Software

Electronic Board

Final Prototype: Wearable Communication Device

Bright and distinct colours where used since deafblind people usually aren’t fully blind and they still rely on their vision to interact with the world

Curves edges and different button shapes because touch is the main sensorial experience the user will have with the product.

Calmly Bedside Companion

Project Developed for the course: TU Delft: The Delft Design Approach

Personal device designed to improve your mornings by gently waking you up and updating you on what’s to come.

Timeline

This irregularity impacts the body and mental state

Wake Up Get Ready

Students can’t perform at their best University Students sleeping routines are inconsistent

Who has the problem: University Students

What is the problem: Users wake up stressed due to loud/annoying alarm. The users can’t form a healthy sleeping routine.

What are the relevant context factors?: People who share a room, plugs, limited space.

Prototypes

Desired Characteristics

• Smoother transition from being asleep to awake. Which translates to less stress for the body.

• Soft Morning light for a healthy circadian rhythm.

• Bluetooth connectivity for easy connectivity.

On/Off Mode

On/Off Mode

I want students to feel refreshed and well rested when waking up so they aren’t limited throughout the day.

Final Prototype

Dawn simulator with RGB functionality. AUX, Iphone and Bluetooth connectivity for custom sounds and alarms. Alexa integration to stay updated on your day.

Yummy Buddies Toy Collectibles

Project Developed for

A toy collectible line that creates consciousness and connection to the natural world. Its gliding mechanism allows it to fly no matter how high you throw it. It also includes unique flight paths depending on the “Yummy Buddy”

Research

Brief of TOMY UK

Create a new toy concept that can comfort slightly older kids (5yrs+) to rekindle their love for a toy with a new feature. You will need to include a simple mechanism, electronics or other ‘novel’ trick features. You will be expected to suggest a new ‘cute’ or the ‘gotta have cool’ feature. It should not be a styling exercise, but with a Unique Selling Point (USP). There should be no screens, no online features, no AI and no Apps.

From the direct market research done at multiple toy stores (physical and digital), It was identified that there weren’t many popular trending flying collectible toys. An opportunity was found for a product that could fill this gap in the market. The product, Yummy Buddies, tries to differentiate itself by providing a new experience for the customer.

The closest competitor found was Hatchnimals Pixies Crystal Flyers, a product that can fly and spin, but its steep price (40 £) and the need of being charged prevents it from becoming a collectible & accessible toy.

The main complaint of the competitor’s product was its unreliable mechanism. This caused difficulty when controlling the product, a flight path that was always unexpected and constantly crashes. For these reasons the users didn’t really trust the product, evidence of this is shown on the product reviews.

Ideation

The first step was to generate multiple ideas for possible toys given the brief constraints. There where 3 main ideas that where picked and further developed

Three Main Ideas

• Jumping Creatures: A toy that could be pressed down, the stored energy caused it to jump. Different varieties of the toy could have different interactions (some could have liquid or eyes that open when pressed)

• Battling Animals: A collection that includes multiple animals each with their own unique weapon and action. They can be wind-up so they walk and “attack” other animals.

• Flying Vegetables: Inspired on flying seeds, these toys can be thrown to the air and they will twirl around and fall to the ground. They generate curiosity and awareness on how nature works. Each vegetable will have a unique flying path

Final Idea

Prototyping

Modification

First Prototype Second Prototype Third Prototype Breakage

The first stage of prototyping began by creating a prototype that could achieve the desired twirling flying path. After analysing the symmetry and distribution of weight, a second prototype was developed with foam for the body and acetate for the winds. It could successfully fly but wasn’t very resistant to impacts.

Assembly Painting Development

Final Functional Prototype

The third prototype was designed in CAD, three different versions where 3D printed and tested since problems occurred (breakage, no flight and nonsymmetrical). The final prototype was printed, sanded and assembled. It consisted of a plastic body with acetate wings. The size was small enough for a child to grab and its weight was light so it could be thrown easily.
