  • Publication number: 20190004699
    Abstract: A terminal device is provided which is capable of making a key display with which a user makes an input easily. A hover position detection unit measures a distribution of a physical quantity indicating a degree of approach of an operation finger to a touch panel, and detects a hover position from the distribution of the physical quantity. A target key identification unit identifies, as a target key, a key corresponding to a display region including coordinates of the hover position. A user assistance display control unit generates a display control signal indicating that an assistance display that represents the target key is to be displayed at a different position from a display position of the target key. A display makes a screen display in accordance with the display control signal.

  • Publication number: 20150277661
    Abstract: To suppress the occurrence of operation error with respect to a user operation for indicating an object on a display surface. Display device displays an image on display surface, and can also detect a proximity operation in which finger F is brought close to display surface without making contact and a contact operation in which the finger makes contact with display surface. Display device displays on display surface email composing screen SC1 that includes selectable objects. When a proximity operation that indicates object b1 is detected, display device sets a selection of object b1 to valid and sets a selection of surrounding objects b2 to b5 (objects represented by diagonal hatching in FIG. 6B) to invalid. When detecting a contact operation that indicates object b1 for which selection is set to valid, display device specifies object b1 as a selected object by a user.

  • Publication number: 20150193112
    Abstract: Display device is able to detect a proximity operation in which finger F is brought close to display surface without making contact and a contact operation in which the finger makes contact with display surface. Display device specifies a position of a finger of a user while in a stationary state above display screen as reference position BP1 or BP2 based on the proximate operation of the user. When display device specifies reference position BP1 or BP2 after screen SC1 including selectable objects is displayed on display surface, display device enlarges and displays objects located in specific region Ts according to the specified reference position (objects having reference sign “M” at the end). This allows for supporting the user in indicating by a contact operation of an object located at a position further away from the finger when the user operates display device with one hand.
