TorchLight© “An Assistive Tool to Locate People and Objects with a Multimodal Thermogram Interface”

The application displays a simplified high-contrast representation of the thermal signatures within the view of the camera.

VEMI worked collaboratively with MOAI Technologies to develop and test an assistive tool that utilizes thermal signatures to provide information about people and objects in a scene. The application was created at by the team and MOAI Technologies, while a group at the VEMI lab provided debugging and constructive feedback on interface design with a focus on accessibility to help mold this application into a functional assistive tool.

I worked with Nicolas Giudice to provide feedback on each iteration of the application design phases. Additionally, I worked on developing a research study procedure designed to test the capabilities of the application in comparison to user’s navigations using their everyday mobility tools. The research procedure will record the time it takes participants to locate open seats in a variety of setups, and participants will be queried as to how many bystanders they were aware of in the scene. This study will be run in early 2017.

Design considerations for this application required us to consider the resolution of touch, and resulted in our decision to present simplified representations of thermal signatures, rather than the jagged and complex thermal signatures the application initially provided. Audio and haptic feedback was also carefully considered and tweaked based on pilot in-lab testing. Click here to find out more about the TorchLight© “An Assistive Tool.
