2. TRing

TRing offers a novel method for bringing interactivity to objects by embedding a small magnet in them and using a finger-worn device. No time-consuming post processing is needed. Using a magnetic-sensing technique, the system tracks the user’s fingertip around the embedded magnet.

TRing can thus easily replace conventional physical interface elements such as buttons and sliders. Our work will benefit HCI practitioners as well as general users who want to quickly implement a personalized physical interface without having deeper knowledge of electronic components.

3. VRRRRoom Reading-room conditions such as illumination, ambient light, and display luminance play an important role in how radiologists analyze and interpret images.

Indeed, serious diagnostic errors can appear when observing images through everyday monitors. Typically these occur whenever professionals are ill positioned with respect to the display, or when they visualize images under improper light and luminance conditions.

VRRRRoom combines immersive
HMDs with interactive surfaces
to support radiologists in
analyzing medical images and
formulating diagnostics. In this

electronic components. 3

The system combines virtual reality and desktop touch interactions to aid radiodiagnostics and cancel out improper light and luminance conditions.
