  • Patent number: 10139937
    Abstract: Architecture that enables single and multi-modal interaction with computing devices, as well as interpreting user intensity (or liveliness) in the gesture or gestures. In a geospatial implementation, a multi-touch interaction can involve the detection and processing of tactile pressure (touch sensitive) to facilitate general navigation between two geographical points. This is further coupled with providing detailed information that facilitates navigation and turn-by-turn directions. This includes the use of time and/or pressure to release or increase the zoom level of map tiles, the touching of the two geographical points and speaking to obtain directions between these two geographical points, and the blending of tiles to create a compelling user experience, where the map is in different levels of zoom on the same view.

  • Patent number: 10120456
    Abstract: In a wearable terminal, a controller determines whether a direction of a display surface detected by a detector is within a first angle range. In a case where a latest direction of the display surface is out of the first angle range, the controller puts the display in a sleep state, but otherwise the controller puts the display in an active state. Furthermore, the controller specifies a second angle range from the second reference direction. The controller switches the display from the sleep state to the active state in a case the controller determines that the plurality of directions of the display surface detected in the first period and that the direction of the display surface newly detected by the detector is out of the second angle range. In the second display control, the display is switched from the sleep state to the active state even when the newly detected direction of the display surface is out of the first angle range.
