Abstract:
Systems and methods are employed for implementing haptics for pressure sensitive keyboards, such as the type of keyboards having keys that produce alternating digital open/short signals that emulate actuation of conventional “momentary on” digital keys. The disclosed systems and methods may be implemented to provide haptics for both touch typing and variable pressure sensitive operation of a pressure sensitive keyboard. Users of a variable pressure keyboard may be provided with a variable pressure haptics effect, e.g., to enable the user to intuitively understand from the haptics vibration produced by the key how much pressure they are applying to a given key at any given time. Vibration characteristics (e.g., vibration rate, vibration waveform pattern, etc.) of a given pressed key may be varied in real time in coordination with, or in response to, corresponding changes in user pressure applied to the same given key.
