General Project Abstract

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. This 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. This allows him to design ergonomic-oriented products such as cell phones, computer mice, and game controllers. Current scanners have a limited field of view. Increasing this field of view results in poor quality scans. Therefore, scan technicians must verbally navigate participants into the needed position and orientation. This causes participants to take 30 minutes or longer to find the correct scan position and orientation. Team 523's design strives to shorten these scan times. Shortening scan times will increase productivity and save money.

Team 523 has designed a mixed reality wearable. This wearable will track and display position and orientation of a user's hand. The AprilTag, similar to a QR code, will clip onto a bracelet. The bracelet uses a quick remove fastener to reduce motion blur. A 3D camera will track and compile position and orientation data from the wearable's AprilTag. The computer finds the AprilTag and display it as a 3D model on a nearby screen. Most likely a hand or head, the 3D model will allow the participant to match their position to the needed position shown on the monitor. Last, this allows participants to self-correct their position and orientation without any extra verbal direction. An ideal setup would not only allow the team's 3D camera to track full bodies but also track any body type without any verbal direction.
