Abstract
A multi-modal display device is presented. The display device has a shell having an internal projection screen and an opening, a projector emitting a projection beam from inside the shell. There is an optical guide adjusting a position of the projector to aim the projection beam at either the internal projection screen or the opening. A processor coupled to the optical guide may select a display position, wherein different display positions are associated with different display area sizes. The method includes determining a distance between a projector and a user, and automatically selecting a display mode based on the distance.
Claims14
A device comprising:
- a shell having an internal projection screen and an opening;
- a projector emitting a projection beam from inside the shell;
- an optical guide inside the shell, the optical guide adjustably aiming the projection beam in one of a first direction and a second direction, the first direction being toward the internal projection screen and away from the opening, and the second direction being toward the opening;
- a sensor determining a distance between a user and the internal projection screen and continuously monitoring an amount of ambient light around the device, wherein monitoring an amount of ambient light involves comparing the amount of ambient light with a threshold scope;
- a processor coupled to the sensor and in communication with the optical guide, the processor selecting a direction in which the projection beam is aimed based on the distance;
- and
- a moving mechanism coupled to the optical guide, wherein the moving mechanism adjusts the position of the projector according to the direction that is selected by the processor, and wherein the processor selects the direction based on a type of visual content and the amount of ambient light around the device.
A method, comprising:
- emitting, by a projector, a projection beam from inside a shell of an electronic device;
- determining, by using a sensor, a distance between a user and an internal projection screen that is part of the shell, and an amount of ambient light around the electronic device;
- selecting, by the processor, a direction in which the projection beam is aimed based on a type of visual content and whether the amount of ambient light around the electronic device satisfies a threshold scope;
- and
- adjusting, by an optical guide inside the shell and based on the distance, the direction of the projection beam such that the projection beam is aimed either at the internal projection screen from inside the shell or at an opening in the shell.
A device comprising:
- a shell having an internal projection screen and an opening;
- a projector emitting a projection beam from inside the shell;
- an optical guide inside the shell, the optical guide adjustably aiming the projection beam in one of a first direction and a second direction, the first direction being toward the internal projection screen and away from the opening, and the second direction being toward the opening;
- a sensor determining a distance between a user and the internal projection screen;
- a processor coupled to the sensor and in communication with the optical guide, the processor selecting a direction in which the projection beam is aimed based on the distance;
- and
- a moving mechanism coupled to the optical guide, wherein the moving mechanism adjusts the position of the projector according to the direction that is selected by the processor, and wherein the processor selects the first direction if the distance satisfies a threshold range and a type of visual content is not a movie or a video, the processor selects the second direction if the distance does not satisfy the threshold range and the type of visual content is a movie or a video.
