Benefits of technology

This patent describes a system and method for enhancing haptic effects by receiving an input signal with multimedia data and haptic information, decoding the haptic information, and generating an actuator signal based on the parameter and the haptic information. The system then generates an output signal with the actuator signal and the multimedia data, resulting in a haptic effect. This technology can provide a more immersive experience for users.

Problems solved by technology

Historically, however, portable devices have only featured basic vibration functionality.
The growing variety of different haptic devices creates a dilemma for device designers.

Embodiment Construction

[0014]Embodiments of the present invention provide systems and methods for enhanced haptic feedback. In one illustrative embodiment, a computer-readable medium stores information relating to the performance of a haptic device. A processor receives a media stream with haptic information encoded at a predetermined frequency. A processor uses a band pass filter to extract the haptic information from the media stream. The processor then generates an actuator signal for producing a haptic effect associated with the haptic information. The actuator signal is based, at least in part, on the information stored in the computer readable medium and related to the performance of a specific haptic device. After generating an actuator signal, the processor generates an output signal comprising the multimedia data and the actuator signal. The output signal is in the same format as the input signal. Once the processor generates the output signal, the haptic device may use an actuator to provide a h...

Abstract

Systems and methods for enhanced haptic effects are described. One described method includes receiving an input signal having haptic information and multimedia data, the input signal formatted in a first format, decoding the haptic information from the input signal, and determining a parameter associated with an actuator in a haptic device. The method further includes generating an actuator signal based at least in part on the parameter and the haptic information, and generating an output signal comprising the multimedia data and the actuator signal, the output signal formatted in a second format.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of and claims the benefit of U.S. patent application Ser. No. 11 / 697,374, filed on Apr. 6, 2007, and entitled “Systems and Methods for Enhanced Haptic Effects,” which claims the benefit of U.S. Provisional Application No. 60 / 790,408, filed Apr. 6, 2006, and entitled “A Vibrotactile Effects System,” the entire disclosure of both of which is hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to haptic control technology. More particularly, the present invention relates to systems and methods for haptic effects.BACKGROUND[0003]Portable devices are rapidly evolving into multi-function devices, which incorporate computing, communication, and entertainment functions in one device. Tactile feedback is increasingly incorporated into these portable devices, such as mobile phones, personal digital assistants, and other devices. Historically, however, portabl...
