Visualization of user interactions with a pressure mapping mobile application for wheelchair users at risk for pressure injuries

This study uses a mobile app called AW-Shift© to help wheelchair users with spinal cord injuries prevent pressure injuries. The app provides a live pressure map and reminders to shift weight, and the study visualizes how users interact with these features. The visualizations help understand when and how often users engage with the app's features, such as checking the pressure map or responding to weight shift reminders.

• 1
  Participants used the app differently: some used it throughout the day for spot checks, while others primarily used it in the morning.
• 2
  Adherence to weight shift reminders was generally low, suggesting the live pressure map may be more useful to users.
• 3
  Global pressure alerts were the most frequent type of alert, and disconnection alerts were common for all participants.
