A module type home robot is provided. The module type home robot includes a device module coupling unit coupled to a device module, an input unit receiving a user input, an output unit outputting voice and images, a sensing unit sensing a user, and a control unit sensing a trigger signal, activating the device module or the output unit according to the sensed trigger signal, and controlling the module type home robot to perform an operation mapped to the sensed trigger signal. The trigger signal is a user proximity signal, a user voice signal, a user movement signal, a specific time sensing signal or an environment change sensing signal.

A display device for displaying image information including an image generator circuit and a photo-switchable screen is provided. The image generator circuit outputs an output image. The photo-switchable screen operates in a first operation mode or a second operation mode. In response to the photo-switchable screen operating in the first operation mode, the photo-switchable screen has a first light-transmittance, and the photo-switchable screen generates the image information according to the output image. In response to the photo-switchable screen operating in the second operation mode, the photo-switchable screen has a second light-transmittance. The first light-transmittance is less than the second light-transmittance.

A method includes projecting, with a holographic optical element, a first view of an eye toward an imaging device, and projecting, with the holographic optical element, a second view of the eye, distinct from the first view of the eye, toward the imaging device so that the first view and the second view of the eye are concurrently received by the imaging device. An eye tracking device for performing the method, a holographic optical element used for the method, and a method of making the holographic optical element are also disclosed.

An image projection device includes a projector configured to project an image; and an operation unit configured to receive an operation performed by an operator. The projector is in a projecting state while the operation unit is receiving a pressing operation performed by the operator, and the projector is in a non-projecting state while the operation unit is not receiving a pressing operation performed by the operator.

A control method applied in a display device is provided. The display device includes an image generator and a screen. The image generator is directed to output an output image. The screen is directed to operate in a first operation mode or a second operation mode. The screen has a first light-transmittance in the first operation mode and has a second light-transmittance in the second operation mode. The first light-transmittance is different from the second light-transmittance. In response to the screen operating in the first operation mode or the second operation mode, the image generator outputs the output image onto the screen in a light-emitting period and stops outputting the output image onto the screen in a non-light-emitting period after the light-emitting period.

A projection apparatus includes a matrix expression generation unit which generates viewpoint correction matrices used for a conversion calculation on each of the projection surfaces for an image to be projected, a mask generation unit which generates correction mask data indicating regions corresponding to the viewpoint correction matrices generated by the matrix expression generation unit for the image, and a projection control unit which executes the conversion calculation on the image using each viewpoint correction matrix generated for each corresponding region in the correction mask data generated by the mask generation unit, and thereafter controls the projection unit to project the image.

Flexible substrates are drawn from two terminals provided on a TFT substrate, respectively, and IC chips are mounted on both flexible substrates. Both flexible substrates are placed so that positions of the IC chips provided on both flexible substrates overlap with each other.

A projection video display device, which enlarges and projects an image from an image-displaying means, has a housing and a raisable/lowerable mirror and a power supply, a light source, and a lens unit inside the housing. The raisable/lowerable mirror covers a projection-light opening formed in the top surface of the housing and able to rotate with respect to the housing, and has a convex mirror on the inside surface thereof. The raisable/lowerable mirror covering the top surface of the housing forms a smoothly connected, smooth, convexly curved surface with no height difference between the edge of the raisable/lowerable mirror and the front edge of the opening, and a half-bowl-shaped concavity is formed on at least one side of the raisable/lowerable mirror in the direction of the axis of rotation thereof.

A mobile device for projecting images on a surface and for maintaining a position of the image on the surface. The device including an image rendering module to scan the surface and to modify the image based on data obtained about a three dimensional nature of the surface. The device further including an optical image stabilization to adjust an alignment of the projector based on orientation data of the device, an electronic image stabilization module to shift the image within a projection area based on the orientation data and an image-tracking module to shift the image within the projection area based on changes in a relative positions of the image and a target.

A controller device for interactive gameplay of a video game is provided, including: the controller device being configured to be handheld by a user; at least one motion sensor, said motion sensor generating motion data in response to movement of the controller device when handheld by the user during the interactive gameplay of the video game; a wireless communications device that receives gameplay video over a network from a remotely executing session of the video game; a projector, said projector being integrated with the controller device, said projector configured to project the gameplay video onto a projection surface in a local environment, wherein the projection of the gameplay video is stabilized based on the motion data.
