Patent number: 9626042Abstract: Techniques are provided to improve interaction between a user and a projection system. In some embodiments, an image of a user in front of a display screen is captured. An inference can then be made as to whether a user is touching a display screen based on an analysis of shadows and/or variation of brightness (i.e., intensities) across pixels in the image. For example, it may be inferred that the object is: (1) approaching the screen when a region surrounding a top of the object is characterized by a relatively small brightness variation; (2) hovering near the screen when the brightness variation is large and the region includes a dark extremum (caused by a shadow); and (3) touching the screen when the brightness variation is large and the region includes a light extremum.Type: GrantFiled: April 14, 2015Date of Patent: April 18, 2017Assignee: QUALCOMM IncorporatedInventor: Atid Shamaie

Patent number: 9004700Abstract: A projector system that includes a first input device, a second input device, a control device, a sensor and a phase locked loop (PLL). A phase reference signal is created based on a signal rate of the first input device. A phase feedback signal is created based on the rotational speed of the second input device as it is measured by the sensor. The PLL compares the phase reference signal and the phase feedback signal to determine whether the first input device and the second input device are synchronized. A signal is sent to the control device for the second input device to change the rotational speed of the second input device in response to determining that the first input device and the second input device are not synchronized.Type: GrantFiled: January 25, 2012Date of Patent: April 14, 2015Assignee: International Business Machines CorporationInventor: Casimer M. DeCusatis

Patent number: 8985777Abstract: Wallpaper serving as a screen and display content such as an image to be projected onto the wallpaper are created while maintaining their correlation. The created display content is projected on the wallpaper. The content display system creates a background image, which is a first image serving as a screen, and a second image for a predetermined area on the first image while maintaining their visual relationship, and forms a composite image of the second image on the first image by projecting the second image from a projector onto the predetermined area of the first image.Type: GrantFiled: October 15, 2012Date of Patent: March 24, 2015Inventor: Tetsuya Akiba
