Abstract
A method may include receiving an input signal from a force sensor configured to sense a force associated with a human interaction with a virtual button, comparing the input signal to at least one behavioral model, the at least one behavioral model comprising one or more parameters associated with a valid human interaction with the virtual button, and determining whether a valid human interaction with the virtual button occurred based on the comparing.
Claims30
A method comprising:
- receiving an input signal from a force sensor configured to sense a force associated with a human interaction with a virtual button;
- comparing the input signal to at least one behavioral model, the at least one behavioral model comprising one or more parameters associated with a valid human interaction with the virtual button and the one or more parameters comprising a defined validity window defining a range of input signal magnitude against time for determining the valid human interaction occurred;
- and
- determining whether a valid human interaction with the virtual button occurred based on the comparing.
