Results of medical imaging are typically displayed on two dimensional computer screens. When navigating through 3D volumes and cross-sectional slices, the relative depth of things can seem distorted. This is often due to the lack of physical markers that help the brain calibrate distances. Microsoft is researching a strange new way of interacting with images that relies on a robotically-powered moving touch screen. Here’s a demonstration IEEE Spectrum filmed at TechFest:
