Modeling Mid-air Gestures With Spherical Coordinates

Generally, touchless mid-air gestural interaction use some form of Cartesian coordinate system within the input space. Most implementations map the input space in 3-D and map it to the 2-D of the monitor for output. In our previous work we showed that modeling the interaction space produces better interaction [1]. In this study, we use the Myo armband to show that a modeled interaction space also benefits devices that use spherical coordinates.
