Microsoft Research developed a new doctor aid called AnatOnMe. It uses a pico-projector and a camera to project bone, muscle, tendons and nerves onto the patient’s skin. The idea is to enhance doctor-patient communication. The device can also be used to project onto walls or models, enable printouts from the visit so the patient can look at these later (if the doctor for example recommends exercise, etc) and more tools for the doctor.
The projector used in the prototype is made by Optoma (DLP), I’m not sure which model. Seems to me that these kind of devices could be more useful with a focus-free laser projector. Here’s a nice video from Microsoft showing what it’s all about:
