The processor 701 may control the touch screen 705 to display the user interface in a landscape view or a portrait view according to the gravitational acceleration signal collected by the acceleration sensor 711. The acceleration sensor 711 may also be used for acquisition of motion data of a game or a user.
The gyro sensor 712 may detect a body direction and a rotation angle of the in-vehicle system 700, and the gyro sensor 712 may cooperate with the acceleration sensor 711 to acquire a 3D motion of the user on the in-vehicle system 700. From the data collected by the gyro sensor 712, the processor 701 may implement the following functions: motion sensing (such as changing the UI according to a user's tilting operation), image stabilization at the time of photographing, game control, and inertial navigation.
Pressure sensors 713 may be disposed on a side bezel of in-vehicle system 700 and/or underneath touch screen 705. When the pressure sensor 713 is arranged on a side frame of the vehicle-mounted system 700, a holding signal of a user to the vehicle-mounted system 700 can be detected, and the processor 701 performs left-right hand identification or quick operation according to the holding signal collected by the pressure sensor 713. When the pressure sensor 713 is disposed at a lower layer of the touch display 705, the processor 701 controls the operability control on the UI interface according to the pressure operation of the user on the touch display 705. The operability control comprises at least one of a button control, a scroll bar control, an icon control and a menu control.
The fingerprint sensor 714 is used for collecting a fingerprint of a user, and the processor 701 identifies the identity of the user according to the fingerprint collected by the fingerprint sensor 714, or the fingerprint sensor 714 identifies the identity of the user according to the collected fingerprint. When the user identity is identified as a trusted identity, the processor 701 authorizes the user to perform relevant sensitive operations, including unlocking a screen, viewing encrypted information, downloading software, paying, changing settings, and the like. The fingerprint sensor 714 may be disposed on the front, back, or side of the in-vehicle system 700. When a physical key or vendor Logo is provided on the in-vehicle system 700, the fingerprint sensor 714 may be integrated with the physical key or vendor Logo.
The optical sensor 715 is used to collect the ambient light intensity. In one embodiment, the processor 701 may control the display brightness of the touch display 705 based on the ambient light intensity collected by the optical sensor 715. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 705 is increased; when the ambient light intensity is low, the display brightness of the touch display 705 is turned down. In another embodiment, processor 701 may also dynamically adjust the shooting parameters of camera assembly 706 based on the ambient light intensity collected by optical sensor 715.
Proximity sensors 716, also known as distance sensors, are typically provided on the front panel of the in-vehicle system 700. The proximity sensor 716 is used to capture the distance between the user and the front face of the in-vehicle system 700. In one embodiment, when the proximity sensor 716 detects that the distance between the user and the front surface of the in-vehicle system 700 gradually decreases, the processor 701 controls the touch display screen 705 to switch from the bright screen state to the dark screen state; when the proximity sensor 716 detects that the distance between the user and the front surface of the in-vehicle system 700 gradually becomes larger, the processor 701 controls the touch display screen 705 to switch from the screen-on state to the screen-on state.
Those skilled in the art will appreciate that the configuration shown in FIG. 7 does not constitute a limitation of the on-board system 700, and may include more or fewer components than shown, or combine certain components, or employ a different arrangement of components.
The above description is only exemplary of the present application and is not intended to limit the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present application are intended to be included within the scope of the present application.
