Average person spends more than 18 years of their adult lifetime sitting down, study finds

The average person leads a very sedentary lifestyle – spending 51 hours and 44 minutes seated during a typical week. Continuous sitting is bad for our health. Many people in offices or schools make the mistake of sitting almost all day long. This often results in excessive and one-sided strain on the back and chronic back pain, which becomes a disturbance of concentration.

“How might we make people with a sedentary lifestyle have a proper posture that will help them build a healthier life-long habit?”


"POZY" is the app that allows sedentary people to build a healthier life-long posture habit by giving an alert and suggesting the correct posture to the users.


Three main features to solve people who are suffering from wrong posture and pain: Knowing users’ lifestyle, giving a reminder, and analyzing their environment and posture to give a feedback and build a habit gradually.


Measure Distance

Calculate the most proper height of the desk, the distance or angle between the chair and the desk with ergonomics approach

Time Reminder for Break

Reminds you when it's time to take a break from staying seated, and demonstrate a series of stretches

Scan Posture

Detect user’s posture with a posture detector based on AI and give feedback for correction



I had a conversation with five distinctive users to interview and get feedback. The five users are either a student or office workers who mostly have a sedentary lifestyle and in the range of 20-34 year old, matching my personas


  • Understand attitudes, behaviors, frictions, and aspirations of sedentary people with the app Pozy.

  • Identify the real user’s pain points while sitting for a long time.

  • Get feedback and validate the concept, prototype, and key features of app Pozy


I asked questions about the user's basic lifestyle and introduced an app by showing a storyboard to guide how the user can go through the app. I explained the key feature, and the user gave me detailed feedback and described how the experience was.
