Objective

Design a postural reminder system to provide real-time notifications and feedback about a user’s unhealthy posture, and encourage user to establish and maintain healthy posture.

Targeted Problem

Every inch of forward head posture can increase the weight of the head on the spine by 10 pounds. Habitually unhealthy posture can be very difficult to monitor and correct on one’s own.

Context of the System

1. Neck pain is correlated with prolonged Forward Head Posture.
2. Real-time personalized interventions about postural awareness are correlated with sustained postural gains and reported reduced pain.


Our Target Users

- Suffer from frequent neck pain.
- Often sit in a sedentary position (6+ hours/day).
- Generally have an unhealthy posture.
- Want to maintain a healthy posture.

Their Typical Tasks

- Prolonged mobile phone or laptop use
- Sitting in lectures, meetings
- Driving a bus
- Working on a desk

Concepts

In our brainstorming sessions, our team came up with three main design alternatives to tackle the problem space.

1. Google Glass

A Google Glass application that gives posture feedback to the user on the Glass interface.

2. Body Device

Body sensor that gathers posture information and sends it to a paired mobile phone application

3. Chair Brace

A static chair brace sensor that collects posture information and sends it to a paired mobile phone or web application.

Storyboards

We used storyboards to depict our users using our three design alternatives .

1. User using the google Glass Interface


2. User using the neck sensor with the mobile application

Feedback

Based on the review we got from our peers on presenting our three alternatives at a demo session, we were suggested a fourth design alternative. The idea was to incorporate the body device sensor onto normal earphones to callibrate posture information.

4. Earphone Posture Sensor


After laying down all four design alternatives, we went back to our users and peers to rate the alternatives and give a reason for the same. Based on the user feedback and peer evaluation, the body sensor came out to be the most appreciated choice. We finalized our design to the body device and went ahead to make our application wireframes.
