FitBit for Elderly
The project aims to enhance the elderly care through the utilization of Fitbit technology by the client, Silver Genie. By leveraging Fitbit's capabilities, the project sought to promote active lifestyles, monitor vital signs, and provide real-time caregiver alerts.
Year:
2022
Duration:
6 weeks
Deliverables and Tools:
Interaction Design - Arduino
UX Design - Interviews, Miro
UI Design - Figma
System Design
Target Audience
Designing for elderly users who are alone at home requires a focus on both accessibility and support.
Challenges faced
Designing for elderly users requires extra consideration for accessibility and usability, incorporating high-contrast colors, larger, easy-to-read fonts, and an intuitive, simplified UI.
Research : Link to the extensive research
1.
Secondary Research
An in-depth study about the packages that Silver Genie provides and all the Fit-Bit/ smart watch devices that exist.
2.
Primary Research
Primary Research was conducted by conducting 32 interviews of elderly to understand their pain points and motivations
Problem 1 (UI)
Most elderly feel the need for a companion to stay and interact with. They feel lonely when no one's around
Solution : Community Building through Fitbit
Most elderly need their family around or someone to accompany them throughout the day. Since everyone is busy with their day-to-day schedule that leaves out the elderly alone. Thus connecting them will get them to socialize.
A UI that showcases weather in the background of the watch so that the elderly are aware of what is the weather outside. It also showcases only essentials on the homepage like time, Date, Battery, Steps walked, Call, and Route

Map UI
The map allows the user to view every park, user, and hospitals that are on the way

Contact Book
The user can pick any contact that he sees on the way and call them, set maps to their location, or add them in their favorites (automatically saves in the contact list)

Filters
The User can choose if they want to head back home, find a way to their favorite contact, or go to the hospital

Exercise
Once the user reaches the park the watch will showcase a few simple exercises to give them a kick start
Problem 2 (Interaction)
No Fitbit currently has fall detection and Fall detection is a very important feature when it comes to Fitbit for Elderly.
False alarms are common while exercising, dropping the watch, and swinging the watch in fast motion
Elements used to detect Fall Detection
1.
Pulse Rate Sensor
A Pulse Rate Sensor detects the pulse rate of a human to determine if there is a fall or not

2.
Accelerometer
An Accelerometer detects the motion to understand if it’s a fall or not

Solution : Building a prototype with only Pulse Rate Sensor
When a body is exercising the heart rate increases gradually, but when there is a fall or a stroke the heart rate goes up suddenly.
Function
The LED bulb lights up when there is an immediate change in a person's heart rate

Prototype of building a False Alarm detector with the help of Pulse Rate Sensor
Code Logic
If the pulse rate changes immediately beyond the set limit ie. 60-100 beats per minute, the LED will start blinking.
