Publication number: 20240118112Abstract: A contact-based inductive sensing technique for contextual interactions on interactive fabrics is described. The technique recognizes conductive objects (mainly metallic) that are commonly found in households and workplaces, such as keys, coins, and electronic devices. An apparatus includes an array of a plurality of six by six spiral-shaped coils including conductive thread, sewn onto a four-layer fabric structure. The coil shape parameters were determined based on maximizing the sensitivity based on a new inductance approximation formula. Through a ten-participant study, the performance of sensing technique across 27 common objects was evaluated. A 93.9% real-time accuracy for object recognition resulted.Type: ApplicationFiled: October 16, 2020Publication date: April 11, 2024Applicant: TRUSTEES OF DARTMOUTH COLLEGEInventors: Jun GONG, Alemayehu SEYED, Xing-Dong YANG

Patent number: 11886667Abstract: A finger device initiates actions on a computer system when placed in contact with a surface. The finger device includes instrumentation that captures images and gestures. When in contact with a surface, the finger device captures images of the surface and gestures made on the surface. The finger device also transmits the images and gesture data to the computer system. An application on the computer system matches the images received from the finger device to a representation of the surface, identifies an action associated with the surface representation and gesture, and executes the action. Instrumenting the finger instead of the surface, allows a user to configure virtually any surface to accept touch input.Type: GrantFiled: March 20, 2018Date of Patent: January 30, 2024Assignee: AUTODESK, INC.Inventors: Xing-Dong Yang, Tovi Grossman, Daniel Wigdor, George Fitzmaurice

Patent number: 11519753Abstract: Aspects of the disclosure provide a sensing apparatus including a sensing device, a memory, and processing circuitry. The sensing device includes resonators having respective resonant frequencies. The resonators include an array of inductive coils positioned on a surface of the apparatus. The sensing device can output a signal indicating changes of the resonant frequencies caused by presence of an object proximate to the surface. The memory stores reference signals corresponding to reference objects. Each reference signal indicates changes of the resonant frequencies caused by the respective reference object proximate to the surface. The processing circuitry can receive, from the sensing device, a particular signal indicating changes of the resonant frequencies caused by presence of a particular object proximate to the surface. The processing circuitry compares the particular signal with the stored reference signals of the reference objects to determine an identity of the particular object.Type: GrantFiled: October 8, 2019Date of Patent: December 6, 2022Assignee: Trustees of Dartmouth CollegeInventors: Jun Gong, Xing-Dong Yang

Patent number: 10936083Abstract: A self-powered module for gesture recognition is presented that utilizes small, low-cost photodiodes for both energy harvesting and gesture sensing. Operating in the photovoltaic mode, photodiodes harvest energy from ambient light. In the meantime, the instantaneously harvested power from individual photodiodes is monitored and exploited as a clue for sensing finger gestures in proximity. Harvested power from all photodiodes is aggregated to drive the whole gesture-recognition module including a micro-controller running the recognition algorithm. A robust, lightweight algorithm is provided to recognize finger gestures in the presence of ambient light fluctuations. Two prototypes are fabricated to facilitate user's interaction with smart glasses and smart watches.Type: GrantFiled: October 2, 2019Date of Patent: March 2, 2021Assignee: Trustees of Dartmouth CollegeInventors: Yichen Li, Tianxing Li, Ruchir A.

Patent number: 10684768Abstract: Systems and methods for providing graphical user interface elements optimized for touch-based input in connection with an application that is designed for conventional input received from a keyboard and a mouse. The touch-based graphical user interface elements are displayed when the computer system detects that a user is about to switch from conventional input devices to touch-sensitive input devices. The touch-based graphical user interface elements are hidden when the user provides input with the conventional input devices such that the touch-based graphical user interface elements do not distract from the applications normal operation. The display device includes a sensing capability that enables the computer system to detect when an object, such as a user's finger or a stylus, is proximate to, but not in contact with, the display device.Type: GrantFiled: October 14, 2011Date of Patent: June 16, 2020Assignee: Autodesk, Inc.Inventors: Tovi Grossman, George Fitzmaurice, Xing-Dong Yang, Pourang Polad Irani

Publication number: 20120092253Abstract: The peripheral input and output device embeds a touch-screen display onto a mouse. Users interact with the display of the mouse using direct touch, whilst also performing regular cursor-based mouse interactions. The resulting device has many unique capabilities, in particular for interacting with auxiliary windows, such as toolbars, palettes, pop-ups and dialog-boxes. By migrating these windows onto a peripheral computer mouse challenges such as screen real-estate use and window management can be alleviated.Type: ApplicationFiled: June 22, 2010Publication date: April 19, 2012Inventors: Pourang Irani, Edward Mak, Xing-Dong Yang
