Problems solved by technology

However, traditional haptic solutions require the control of a host controller or processor
That is to say, traditional haptic solutions are usually limited by the host interface communication bottleneck, which limits the variety of haptic effects (such as variable frequency control and gain control)
Additionally, many of these haptic solutions have low power efficiency due at least in part to the on-chip low-dropout regulator (LDO)

Embodiment Construction

[0027] figure 1 An example system 100 is illustrated in accordance with an example embodiment of the invention. System 100 can be a variety of devices, such as a portable media player, smart phone, or game controller and generally includes a touchscreen 102 (which can be a capacitive or resistive touchscreen), a host processor 104 (i.e., a digital signal processor or DSP ), touch screen controller 106, driver 108 (which may be an amplifier), and actuator 110 (which may be a linear actuator, piezoelectric transducer, motor, etc.). Generally, a user can interact with system 100 through touch screen 10 (which is controlled by touch screen controller 106 and host processor 104). According to the user's interaction with the system 100, haptic effects may be generated. Typically, touch screen controller 106 provides a sine wave to actuator 110 (either directly or through driver 108 ).

Abstract

Haptic effect instructions are generated by the host processor (104) in response to the touchscreen (102), wherein the haptic effect instructions correspond to desired haptic effects. The haptic effect instructions are received by the haptic driver (108), and a haptic file from the haptic effect instructions is generated from the haptic effect instructions. The haptic profile includes at least one of a file word, a move word, a wait / stop word, and a branch word, and a sine wave is generated from the haptic profile corresponding to the desired haptic effect.

Description

technical field [0001] The present invention relates generally to haptic effects, and more particularly to haptic controllers and their associated instruction sets. Background technique [0002] Touchscreens are becoming more common, but touchscreens don't inherently have a feedback mechanism (like the audible click from a traditional keyboard). Therefore, tactile or mechanical vibration feedback is emerging as a new technology, which can provide a feedback mechanism that does not exist. However, traditional haptic solutions require the control of a host controller or processor. That is to say, traditional haptic solutions are usually limited by host interface communication bottlenecks, which limit the variety of haptic effects (such as variable frequency control and gain control). Additionally, many of these haptic solutions have low power efficiency due at least in part to the on-chip low-dropout regulator (LDO). Therefore, there is a need for methods and / or devices tha...
