Project Overview

Posture Check: Creative Technological Approaches" explores new ways of giving individuals real-time visual feedback on changes in their posture to help them become more aware of their stance. The physical prototype is a posture awareness device Stryt that detects sitting posture. When a person’s posture deteriorates, the device detects the data wirelessly and shares it with your computer. It provides real-time feedback through varying digital visualisations which notify people about their changing posture in an unobtrusive way.

Project Background

Human posture is crucial for overall health, as poor posture can lead to back strain, depressive symptoms, and low confidence. On average, people sit for about 13 hours daily, making proper sitting posture vital. Poor posture not only affects mental and physical health but also increases stress levels. Discussions with peers revealed that people often overlook their posture until they experience negative effects and often misjudge what good posture feels like.

Traditional posture monitoring methods are often impractical due to being time-consuming and costly. Proper posture aligns the spine correctly, whereas slouching weakens muscles and increases stress. Sedentary lifestyles worsen poor posture, even among physically active individuals.

Inspired by my master's studies at OCAD University, this project aims to develop a wearable device that monitors posture and provides subtle, real-time feedback to encourage proper sitting habits. The prototype uses a microcontroller to detect movement and discreetly notify users when their posture deteriorates, helping them maintain better posture throughout the day.

The development of over 1,200 reports across programs poses a substantial burden for the client, exacerbated by the absence of consistent governance and business rules. Additionally, the presence of unclean and differently structured data compounds the challenge, leading to a lack of a single source of truth.


The primary research question addressed by this thesis is:

What are effective but non-intrusive methods for using existing technologies and interfaces to share posture feedback with users to help them improve their posture awareness?

Research Question

During my research, I identified several limitations. The project began during lockdown, and the target audience was primarily attending school from home, resulting in a lack of first-hand engagement with users. Additionally, the project required expert advice from health professionals, such as chiropractors and doctors, to identify the exact placement of the product. However, due to COVID restrictions, I was unable to consult with any professionals. To keep the project manageable, I focused on standard sensors rather than more innovative approaches. Additionally, the creation of the interface and wireframes for a desktop application connected to the wearable device was not explored.

Tech Habits

Michael is a software engineer in Toronto. He spends long hours coding, leading to back pain and discomfort. He's seeking a solution to improve his posture and reduce pain. Michael enjoys hiking and playing with his kids during his free time.


Prolonged sitting causes significant back pain, impacting his focus and productivity. Michael worries about the long-term effects on his health.

Pain Points

Michael aims to find an easy-to-use solution to monitor and improve his posture, reducing back pain and enhancing his well-being for better work performance.


Understanding the needs, goals, and challenges of our users is essential for developing our posture correction device. This section explores the profiles of typical users affected by prolonged sitting and poor posture, providing insights into their routines, pain points, objectives, and technology preferences. These insights will help us design a solution that effectively addresses their needs and enhances their well-being.

Key takeaways & learnings

Inspired by my pandemic experiences, the STRYT project tackles poor posture from prolonged sitting by integrating wearable technology with non-intrusive feedback to enhance posture awareness.

Throughout the STRYT project, I discovered the effectiveness of providing subtle, non-intrusive feedback to enhance posture awareness. The use of wearable technology and visual cues proved to be more user-friendly and less distracting than conventional haptic devices.

Implementing Research through Design and iterative approaches highlighted the importance of integrating form and function in wearable tech. This methodology demonstrated the value of non-intrusive visual feedback in training users’ visual memory.

User feedback emphasized the need for a streamlined feedback system, which will guide future refinements to better meet user needs and promote healthier habits. Designing for ease of integration into daily routines, with a compact device and intuitive desktop app, ensured a seamless and effective user experience.

Overall, the project underscored the significance of user-centered design and continuous improvement in creating solutions that address real user needs and enhance daily life.
