Abstract: A display system includes: a display screen having a first display area; a processor configured to modulate laser beams to be emitted from a laser projector according to a pre-stored holographic image data source to obtain modulated laser beams; the laser projector configured to project the modulated laser beams to create a first holographic image in front of the first display area; and at least one photodetector configured to collect first gesture information about a first gesture through which the first holographic image is controlled by a viewer. The processor is further configured to generate a first control signal according to the first gesture information, and re-modulate the laser beams to be emitted from the laser projector, so as to create a second holographic image corresponding to the first control signal.

Abstract: The present disclosure discloses an information exhibiting device and method. The information exhibiting device includes a display component and an information acquisition component that are connected to each other. The information acquisition component is configured to acquire target information. The display component is provided with an information exhibiting interface which may be displayed on the display component after the information exhibiting device is powered on. The information exhibitive interface includes a target information exhibiting region. The display component is configured to exhibit the target information, which is acquired by the information acquisition component, in the target information display region. The information exhibiting device provided by an embodiment of the present disclosure may guarantee that memo information has low probability of getting lost. Thus, a user may be effectively reminded.

Abstract: The present disclosure provides an electronic device and an alarm control method. The electronic device includes: a detecting component, configured to obtain a physiological feature parameter of a user; a first input component, configured to receive verification information inputted by the user; and a first processing component, configured to receive the inputted verification information via the first input component when determining that the physiological feature parameter obtained by the detecting component satisfies a presupposed condition, perform a normal operating mode of the electronic device when determining that the verification information is first preset verification information, and perform an alarm operation when determining that the verification information is second preset verification information. The alarm operation at least includes transmitting first prestored information to a first object.
