Patent number: 8730169Abstract: The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.Type: GrantFiled: April 30, 2010Date of Patent: May 20, 2014Assignee: Pixart Imaging Inc.Inventors: Cho Yi Lin, Yen Min Chang, Yao Ching Hsu, Yi Hsien Ko

Patent number: 8488204Abstract: Various types of ink corresponding to non-overlapping wavelength domains in absorbing lights are utilized on a pattern displaying medium for marking coordinate dots and data dots of a plurality of data blocks. While a scanning device is utilized for scanning the pattern-displaying medium, the marked coordinate dots and data dots are precisely recognized and read. While the pattern displaying medium is to be marked, the coordinate dots are marked in advance, and then the data dots are marked according to the marked coordinate dots for preventing positioning errors. Besides, at least one locality dot is used in each data block. While the scanning device is utilized for scanning the pattern displaying medium, a reading direction of each data block is indicated by the at least one locality dot so as to precisely read dots of each data block.Type: GrantFiled: May 6, 2008Date of Patent: July 16, 2013Assignee: PixArt Imaging Inc.Inventors: Shou-Te Wei, Cho-Yi Lin, Yao-Ching Hsu
