User Study #1
The problem investigated was whether a person can use an imaginary interface do perform character input. The imaginary device consists of a persons hands, one to make a reference point, and the other to perform interactions in a virtual space. Users would repeat characters and the error would be determined on how well the recognition device could read the characters read on an imaginary screen. Previous experiments have shown that users will not have enough precision to differentiate the letters "D" and "P."
