Touch Pad Disc Jockey Controller
First Claim
1. A disc jockey controller, comprising:
- a substantially circumferential shaped touch sensitive surface;
said touch sensitive surface has a central portion and a circumferential portion;
said central portion is disposed to respond to linear motion imparted by the user;
said circumferential portion is disposed to respond to circumferential motion imparted by the user;
a processing device disposed to process data imparted from said touch sensitive surface and create a control signal;
said control signal is disposed to communicate with means for processing an audio signal in order to manipulate a digital audio stream;
wherein user manipulation of said central portion is used to modulate the audio data stream in order to impart a “
scratch effect”

Abstract
The present invention pertains to the field of control and manipulation of a digital audio signal by a user manipulable touch sensitive control surface. The present invention is specifically applicable to user manipulation of digital audio signals by disc jockeys (DJs).
A touch sensitive surface substantially circumferential in shape is divided into two regions: an inner or central portion and an outer or circumferential portion. The inner portion responds to linear motion imparted by the user while the outer portion responds to circumferential motion. The linear motion imparted by the user in the central portion is used manipulate a digital audio data stream in order to impart a scratch effect.

7. A disc jockey control device, comprising:
-
a substantially circumferential shaped touch sensitive surface; said touch sensitive surface has a central portion and a circumferential portion, said circumferential portion comprising one or more circumferential sub-portions; said central portion is disposed to respond to linear motion imparted by the user; at least one said circumferential sub-portion is disposed to respond only to circumferential motion imparted by the user; a means to select mode of operation; a processing device disposed to process data imparted from said touch sensitive surface and create a control signal; said control signal is disposed to communicate with means for processing a digital audio signal in order to manipulate a digital audio stream; said means to select mode of operation configures said processing device to accept or ignore user input from said central portion and at least one said circumferential sub-portion. - View Dependent Claims (8, 9, 10)
