Patent number: 11436734Abstract: Interactive region coloring techniques as implemented by a computing device are described to provide a user with the tactile experience of coloring in a region with digital paint, while at the same time allowing the user to manually fill the region with digital paint with more apparent skill and precision than they may input.

Patent number: 11429205Abstract: A stylus having an applied force-sensitive tip-switch is disclosed. The stylus includes a tip-switch responsive to a variable applied force. Control circuitry determines whether the tip-switch has made contact with an object and, if so, the magnitude of the applied force resulting from the contact. The circuitry then encodes a signal that varies with the magnitude of the applied force and transmits the encoded signal to a computing device, enabling the computing device to indicate the two- or three-dimensional path of the tip-switch in the stylus on a computer screen. The circuitry also monitors a manual override switch that activates an encoded override signal for interpretation and use by the computing device while indicating the path of the tip switch on a computer screen.Type: GrantFiled: July 31, 2014Date of Patent: August 30, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Bradley Short, Jinman Kang, Ben Wynne, Jamie Etcheson
