Assignment: Redesign Digital Otoscope
Assignment: Redesign Digital Otoscope
Embedded Files
In my Introduction to Engineering - Reverse Engineer Medical Devices class (Winter 2023) at the University of Michigan, each team was assigned an at-home medical device to redesign. We were fortunate enough to get the digital otoscope, a handheld ear camera diagnostic device. The user holds a camera wand in their ear and views the image on a tablet screen. Our first step was to conduct benchmark tests, receive user feedback, and find problems with this device.

The camera notch seems simple but greatly increases the user's ability to orient the camera and get a quality picture.
