Embodiment Construction

[0021] Exemplary but non-limiting embodiments of the present invention provide an application programming interface (API), and methods of using the API to define and utilize vibration control pulses 21 . This interface provides a means to accurately output short vibration effects, control the intensity of the effects to provide sharp tactile feedback, and support the adjustment of tactile feedback. The vibration control pulse 21 consists of a positive voltage start pulse and a negative voltage stop pulse, which have a changeable polarity to allow bi-directional control of the vibration direction. By selecting parameters that define the precise shape and duration of the vibration control pulse 21, the API can be applied in user equipment, such as in mobile phones and gaming devices, to economically provide finely controllable haptic and tactile effects.

[0022] Furthermore, exemplary but non-limiting embodiments of the present invention disclose a robust control strategy for d...

Abstract

A method includes defining a plurality of parameters for a vibration control pulse comprising a start pulse and a stop pulse, and outputting the vibration control pulse to a vibration element to provide tactile feedback.

Description

technical field [0001] Teachings in accordance with exemplary embodiments of this invention relate generally to vibration control interfaces. Background technique [0002] Mechanical vibrations are used in traditional electronic equipment for various purposes. Mobile phones and pagers use mechanical vibrators to provide vibrating alerts of incoming calls or messages. Game controllers use mechanical vibrators to provide vibration effects to the user in the controller, for example to simulate game mechanics. In general, traditional mechanical vibrators are either binary, with or without vibration effects, or have very few vibration settings, with 2 or 3 or so that vary only in the intensity of the vibration effect set up. [0003] It is known to provide tactile feedback for displays of mobile devices (see, for example, the paper "Ambient Touch: Designing Tactile Interfaces for Handheld Devices" by Poupyrev et al., CHI Proceedings, Vol. 4, No. 2). Current vibrators are typi...
