Ergonomic studies were printed to verify the grip and button layout. A neck strap was added during development as it was found to reduce fatigue during long scanning sessions. Additionally, the team built various simulated environments (such as an aircraft cabin, shown below) to test scanning in multiple positions.
The housing surfaces and part construction were iteratively refined over many weeks of discussion with Ishamel Adams and Keith Alsberg. Sample notes taken during these discussions are shown below, and cover everything from screw placement to the flow of chamfers.
