  • Patent number: 11340705
    Abstract: Implementations provided herein relate to correlating available input gestures to recently created application functions, and adapting available input gestures, and/or user-created input gestures, to be correlated with existing application functions. Available input gestures (e.g., a hand wave) can be those that can be readily performed upon setup of a computing device. When a user installs an application that is not initially configured to handle the available input gestures, the available input gestures can be correlated to certain functions of the application. Furthermore, a user can create new gestures for application actions and/or modify existing gestures according to their own preferences and/or physical capabilities. When multiple users elect to modify an existing gesture in the same way, the modification can be made universal, with permission from the users, in order to eliminate latency when subsequently adapting to preferences of other users.

  • Patent number: 11315517
    Abstract: A modulated data signal is generated so as to change such that a length of a data period indicative of a timing of writing of the gradation voltage signal to each of the pixel portions becomes a length according to a distance from the data driver to each of the pixel portions. The timing control unit writes a video data signal to a memory at a timing according to a data period of the video data signal. The timing control unit reads the video data signal from the memory at a timing according to a period as a result of correction of a data period of the modulated data signal on the basis of a difference between an average value of lengths of the data periods of the video data signals and an average value of lengths of the data periods of the modulated data signals.

  • Patent number: 11275240
    Abstract: Image light that travels between opposed parallel surfaces (100a, 100b) of the light guide (10) while being reflected by the opposed parallel surfaces is partially reflected by the outgoing-side reflection surfaces (102a, 102b) of a beam splitter. The image light took out from the light guide (10) is partially reflected by the two combiners (14, 15) and advances towards eyes of a user (E). The distance D of the combiners (14, 15) is set to be equal to or larger than A1/(2 cos ?·tan ?) and equal to or smaller than A2/(2 cos ?·tan ?), where ? is an incident angle ? of the image light to the combiner (14, 15), A1 is a light flux width of the image light reflected by one outgoing-side reflection surface, and A2 is a light flux width of the image light emitted from all of the outgoing-side reflection surfaces. This makes it possible to reduce the overlapping of images formed when viewed from the user, avoid the generation of partial image omission, and improve visibility.

  • Patent number: 11237722
    Abstract: An electronic device includes a display unit, a touch panel, and a controller. The display unit displays a pointer that points out an input location. The touch panel detects a touch operation on the display unit with one of a user's finger and a pointing device. The controller controls a display location of the pointer on the display unit and performs an input process in accordance with the touch operation on the touch panel. Moreover, the display unit displays a predetermined region for use in designating, as the display location of the pointer, a location different from a location of the touch operation. When the controller detects a continuous touch operation from an inside to an outside of the predetermined region, the controller moves the pointer at a location different from a touch location in the continuous touch operation, in accordance with movement of the touch location.
