Patent number: 9807366Abstract: A single-lens two-channel reflector provides the capability to switch between two-dimensional and three-dimensional imaging. The reflector includes laterally displaceable outward reflectors and displaceable inward reflectors that can simultaneously provide left and right images of a scene to an imager, and controllers for controlling relative distance between the outward and the inward reflectors, and for controlling deflection angle of the inward reflectors, so as to enable the adjustment of disparity and convergence angle.Type: GrantFiled: January 24, 2017Date of Patent: October 31, 2017Assignee: AMCHAEL VISUAL TECHNOLOGY CORPORATIONInventor: Kai Michael Cheng

Patent number: 9507437Abstract: Methods and systems for surface-free pointing and/or command input include a computing device operably linked to an imaging device. The imaging device can be any suitable video recording device including a conventional webcam. At least one pointing/input device is provided including a visible point light source emitting light in a wavelength defining a predetermined color. The at least one pointing/input device may be a conventional optoelectronic computer mouse. The imaging device captures one or more sequential image frames each including a view of a scene including the visible point light source. One or more software programs calculate a position and/or a motion of the at least one point light source in the captured image frames by identifying colored areas corresponding to the point light source and mapping those colored areas to a position and/or motion of a visual marker such as a cursor in a graphical user interface.Type: GrantFiled: November 26, 2013Date of Patent: November 29, 2016Assignee: AMCHAEL VISUAL TECHNOLOGY CORPORATIONInventors: Kai Michael Cheng, Yushiuan Tsai, Hsien-Chang Lu

Patent number: 9310851Abstract: A three-dimensional user interface system includes at least one pointing/input device and an imaging device configured for capturing one or more image frames each providing at least two different views of a scene including the at least one pointing/input device. The imaging device is a multi-view imaging device which provides at least two different views of the scene per each of the one or more image frames captured. One or more software programs calculate from reference points in the image frames at least a spatial and a velocity parameter of the at least one pointing/input device when moved through a three-dimensional space and for rendering on a graphical user interface of a computing device a visual marker corresponding to the spatial and velocity parameters of the at least one pointing/input device in three-dimensional space. Methods for three-dimensional pointing and/or data input incorporating the described system are also provided.Type: GrantFiled: October 31, 2013Date of Patent: April 12, 2016Assignee: AMCHAEL VISUAL TECHNOLOGY CORPORATIONInventors: Kai Michael Cheng, Yushiuan Tsai

Patent number: 9201519Abstract: Methods and systems for surface-free pointing and/or command input include a computing device operably linked to an imaging device. The imaging device can be any suitable video recording device including a conventional webcam. At least one pointing/input device is provided including first and second sets of visible point light sources, wherein the first and second sets emit differently colored light. The imaging device captures one or more sequential image frames each including a view of a scene including the first and second sets of visible point light sources. One or more software programs calculate a position and/or a motion and/or an orientation of the pointing/input device in the captured image frames by identifying colored areas corresponding to the first set of aligned visible point light sources. Certain activation patterns of individual point light sources are mapped to particular pointing and/or input commands.Type: GrantFiled: December 12, 2013Date of Patent: December 1, 2015Assignee: AMCHAEL VISUAL TECHNOLOGY CORPORATIONInventors: Kai Michael Cheng, Yushiuan Tsai, Hsien-Cheng Lu

Patent number: 8964004Abstract: A system for providing a three-dimensional representation from a single image includes a reflector apparatus for providing an image of a scene comprising three adjacent views of the scene. The apparatus defines a left light path, a center light path, and a right light path, wherein each of the left light path and the right light path comprise opposed reflective surfaces for redirecting light, whereby light passing through the left light path, light passing through the right light path, and light passing through the center light path converge at a nodal point of an imager to create an image of the scene providing three adjacent views of the scene arrayed in a three-by-one rectangular grid. A client computing device receives data from the imager and transforms the data into a stereoscopic image or an image-plus-depth rendering, and/or converts or switches back and forth between two-dimensional and three-dimensional images.Type: GrantFiled: September 20, 2010Date of Patent: February 24, 2015Assignee: Amchael Visual Technology CorporationInventor: Fuhua Cheng
