Reduction of haptic noise feedback in system
First Claim
1. An information handling system comprising:
- a haptic generator to generate haptic effects including haptic noise; and
a codec to capture audio input and to produce digital data representing the audio input, and to;
receive characteristics of sound representative of haptic noise entering the codec, the characteristics including frequencies and pulse periods;
detect generations of haptic effects, the generations occurring after the characteristics are received; and
reduce effects of haptic noise on the digital data based upon the received characteristics of the sound;
wherein the detection includes a haptic noise reducer receiving notice of the generation of haptic effects;
the haptic generator generating haptic effects including haptic noise comprises the haptic generator generating a first type of haptic noise and a second type of haptic noise;
the haptic noise reducer receiving notice comprises the haptic noise reducer receiving characteristics of sound representative of the first type of haptic noise and the second type of haptic noise; and
the haptic noise reducer receiving notice comprises the haptic noise reducer receiving notice of which of the two types of haptic noise is being generated.

Abstract
An information handling system has a haptic generation module to generate haptic effects including haptic noise and a haptic noise reduction module. The haptic noise reduction module receives characteristics of sound representative of haptic noise generated by a haptic generation module of a device and entering an audio input module of the device, the characteristics including frequencies and timing. It also detects the generation of haptic effects, the generations occurring after the receiving characteristics. It also reduces the effects of haptic noise on digital data representing audio input to the device based upon the received characteristics of the sound. It may reduce the effects by subtracting amplitudes of audio waves representing the haptic noise from amplitudes of audio waves representing the audio input.
