Title:
USER INPUT DEVICE HAVING DOUBLE-SIDED TOUCH PAD AND ADDITIONAL FUNCTION
Document Type and Number:
WIPO Patent Application WO/2012/015182
Kind Code:
A2
Abstract:
The present invention relates to an input device in which a touch pad as a capacitive type user command input unit, a laser pointer as an additional function, and low frequency vibration, and ultrasonic oscillation functions and the like are coupled with each other. The present invention can simultaneously perform a function of the laser pointer by coupling a structure in which the touch pad for receiving user commands is symmetrically arranged on upper and lower surfaces of the input device with an additional laser LED for the convenience in design which is related to a driving operation of the input device. In addition, the present invention can intermittently perform a function of a massager as a health care device by coupling a vibration motor as a low frequency vibration unit with a piezoelectric element as an ultrasonic oscillator, can assist the function of the massager by coupling an infrared LED, an illuminating LED and the like, and enables the lighting LED to perform a function as a lamp for work.
