Prototype

Prototypes enable us to visualize our ideations. We did Lo-Fi Interactive Prototype, Annotated Wireframes, and Hi-Fi Interactive Prototype and gradually improved our product based on feedback. 

LoFi Prototypes

 Our Lo-Fi prototype includes both a physical and virtual prototype. The physical prototype helps us to understand the suitable screen size and length of the wrist strap. The virtual prototype is built with Figma to visualize the interface and flows.

Virtual Prototype w/ Annotated Wireframes

It is a low-fidelity, interactive, prototype to test our ideation. Three workflows are highlighted which include medicine reminder, voice assistant, and chat with contacts. The medicine reminder flow shows the steps from adding a new medication to altering the user. The voice assistant flow simulates how it helps turn on lights for the user. The chat with contacts flow presents how a user message, call, and add contacts.  

Physical Prototype

The physical prototype was made of simple materials such as rubber belts and sponge mats. We used the physical prototype to figure out the most appropriate size of the screen and the length of the wrist strap.

Simple Evaluation

We first specified a plan to evaluate the experience of our tram’s design. Then we implemented a usability experiment with 8 participants – 4 Senior participants aged 70-85 and 4 young adult participants who have senior family members living alone. By interviewing stakeholders, we achieved a few findings that indicated the insufficiency of our Lo-Fi Prototype. Based on that, we developed a list of solutions to improve.

Our Findings

1 / Design Issues

  • Home Page Feeling Bland

  • Text Too Small

2 / Voice Assistant Problems

  • What to do if accidently say wrong thing?

  • How to edit a voice input?

3 / Text & Function Clarifications

  • Confusion in Text Meaning

  • Bluetooth Device Pair Process unclear

Our solutions

  • Colored icons help users distinguish each of the watch’s functions.

  • Customizable background, texts, and icons.

  • Enlarge the fonts and ability to connect with a big screen (projection function)

  • Having a voice assistant helps the user navigate through the smartwatch (screen reader)

  • Allow users to edit and read the device’s interpretation.

  • Add a descriptive icon and change the “simulation” wording to “Chat bot”

  • A disclaimer telling the user to read the product details on how to link it to the device.

HiFi Prototypes

The Hi-Fi Prototype is a full demonstration of our product. Based on the user evaluation, we made a lot of changes to make our system more usable. For example, we’ve added a family member Assistant Phone App to help senior citizens set up their devices. Another big change we did was the instruction for using the watch for first-time users. There is also a tutorial for using the accessibility features such as the screen reader.

WatchOS
Prototype

The interactive WatchOS is what we designed to create Independence and Security for seniors. 

Family Assistant APP 
Prototype

Working as a helper App used by family members, the Family Assistant App enable them to better setting up the watchOS and protecting the senior.
