Secure Step
Introduction
As part of the lecture "User-centered development", we have developed a platform that is intended to make everyday life easier for care staff in an institution with difficult-to-educate children. The focus is on maintaining the children's privacy and education. We used the design thinking process, which means that we first looked for pain points in institutions. One of the most frequently mentioned pain points was the overburdening of staff in ensuring the well-being of all children. In addition, it sometimes happens that certain children run away from the institution.
Technologies
We have also looked at the technology that will make this project a reality. The sensor technology should answer three big W questions: Who? Where? What? We quickly realized that there is no single technology that meets all requirements. That's why we have to deliberately use several technologies that work together to collect the necessary information. This is achieved with "sensor fusion", or in other words, a logic that can use probabilities to combine different raw data into a probable statement.
Anonymising Video Recordings
We noticed video recordings would be required in more difficult situations, but privacy was a non-negotiable for us. We also looked into anonymizing the video recordings. We found various open source solutions based on artificial intelligence for this purpose. With one of these solutions, Mediapipe, we were able to recognize a person in front of a camera and use Python to recognize that person's pose and recreate it with lines. In this way, the child's privacy is maintained and the caregivers can still ensure that the child is well.
→ Our Final Prototype
Lastly, we developed a custom dashboard for the caregivers. On the dashboard, you can view the group's building plan, including all entrances and exits, as well as the common areas and clients' rooms. You can also change floors by using the platform arrows located directly next to the building plan. Below the building plan you can also find information about the clients, such as their level. To the right of the building map is an area for notifications, for example when someone leaves the main entrance. Below the notification map is another map with boundary data, which can vary from facility to facility.
