Applying Fitts' Law to Gesture Based Computer Interactions
2015
Procedia Manufacturing
Preserved Fulltext
Overall, the findings suggest that gesture-based devices can be characterized by Fitts' law in a similar fashion to conventional 1D or 2D devices. ...
Results showed that the mean movement time was highly correlated with the target's index of difficulty for all devices, providing evidence that Fitts' law can be extended and applied to gesture-based devices ...
Since the introduction of the computer, Fitts' law has been used to test input devices for pointing and selecting. ...

The relationship between the performance of a console operation and the operator's reaching actions was investigated by applying Fitts' law and by examining a state transition of the operation. ...
The results showed the covariance of the fitting error to Fitts' law decreased as the operators' skill improved, although the fitting itself to the law was not sufficiently good. ...
