Problems solved by technology

[0003] One disadvantage of existing haptic systems is that existing methods of processing the signal from a force sensor and generating a haptic response to it often have a longer than desired latency, so that the haptic response may be noticeable from the user's interaction with the force sensor. Delay
Therefore, in applications where the haptic system is used for mechanical button replacement, capacitive sensor feedback, or other applications, the haptic response may not effectively mimic the feel of a mechanical button click

Abstract

Embodiments described herein relate to methods and apparatuses for providing a haptic output signal to a haptic actuator. A controller comprises an input configured to receive a force sensor signal from at least one force sensor; and a haptic output module configured to generate a haptic output signal for output to a haptic actuator; wherein the haptic output module is configured to: responsive to determining that the force sensor signal indicates that a force level applied to the at least one force sensor exceeds a first threshold, trigger output of the haptic output signal; and during output of the haptic output signal, adjust the haptic output signal based on the force sensor signal.

Description

technical field [0001] Embodiments described herein relate to methods and apparatus for controlling haptic output signals based on varying input signals received from a force sensor system. Background technique [0002] Linear resonant actuators (LRAs) and other vibration actuators (e.g., rotary actuators, vibration motors, etc.) are increasingly used in mobile devices (e.g., mobile phones, personal digital assistants, video game controllers, etc. ) or other systems to generate vibratory feedback for user interaction with such devices. Typically, a force / pressure sensor detects user interaction with the device (eg, a finger pressing a virtual button of the device), and in response thereto, a linear resonant actuator vibrates to provide feedback to the user. For example, a linear resonant actuator may vibrate in response to a force to mimic the feel of a mechanical button click to the user. [0003] One disadvantage of existing haptic systems is that existing methods of pro...
