Eyemic

The concept of hands free surgical microscope has become increasingly popular in the domain of microsurgery. The higher magnification, the smaller field of view, necessitates frequent interaction with the microscope during an operation. Researchers showed that manual (hand) interactions with a surgical microscope resulted in disruptive and hazardous situations. Previously, we proposed the idea of eye control microscope as a solution to this interaction problem. While gaze contingent applications have been widely studied in HCI and eye tracking domain the lack of ocular based eye trackers for microscope being an important concern in this domain. To solve this critical problem and provide opportunity to capture eye movements in microsurgery in real time we present EyeMic, a binocular eye tracker that can be attached on top of any microscope ocular. Our eye tracker has only 5mm height to grantee same field of view, and it supports up to 120 frame per second eye movement recording.
