Mixed Reality Wearable

From the toothbrush you hold in the morning to the seat in your car, ergonomic products make your life more comfortable. Since consumers dictate the market, 3D scanning has recently grown in popularity, which has caused increased demand for more consumer-friendly and ergonomic products. The team’s sponsor works as a professional ergonomic engineer. He uses scanners to take 3D pictures of various body parts, allowing him to design ergonomic-oriented products such as cell phones, computer mice and game controllers. 

Current scanners have a limited field of view but increasing this field of view results in poor quality scans. Therefore, scan technicians must verbally navigate participants into position and orientation, increasing the time for scanning to 30 minutes. Our design strives to shorten these scan times to increase productivity and save money.

We designed a mixed reality wearable that tracks and displays position and orientation of a user’s hand. The AprilTag, similar to a QR code, clips onto a bracelet. The bracelet uses a quick-remove fastener to reduce motion blur. A 3D camera tracks and compiles position and orientation data from the wearable’s AprilTag. A computer finds the AprilTag and displays it as a 3D model on a nearby screen. 

Most likely a hand or head, the 3D model allows the participant to match their position to the prescribed position shown on the monitor. This allows participants to self-correct their position and orientation without any extra verbal direction. An ideal setup would not only allow this 3D camera to track full bodies but also track any body type without any verbal direction.
