    Abstract: An electronic device includes an illumination module, an image projection module, a camera module and at least one processor. The processor, coupled to the illumination module, the image projection module and the camera module, determines that the electronic device executes a first or second operating mode according to an operation instruction of a user. When the first operating mode is executed, the processor enables the illumination module to generate a medium color temperature light, simultaneously enables the image projection module to project a window screen onto a plane, and allows the use to operate the window screen on the plane. When the second operating mode is executed, the processor enables the illumination module to generate a high color temperature light, simultaneously enables the image projection module to project a preset pattern onto the plane, and turns on the camera module to allow the user to take photo or image.

    Abstract: A picture selection method of projection touch for a projection touch system is provided. The projection touch system includes an image projection module, a sensing module, an image recognition module including at least one camera module and a processing unit. The picture selection method includes: the sensing module sensing and transferring a first projection coordinate on the target picture at a first time point of a sensing action; the sensing module sensing and transferring a second projection coordinate on the target picture at a second time point of the sensing action; the processing unit selecting at least one to-be-selected picture in the target picture based on the first and second projection coordinates and generating a set of selected image data; and the processing unit controlling the selected image data projected by the image projection module to move to a designated position according to a movement instruction of the user.

    Abstract: A computer system having a sensing function includes a base, a first light emitting assembly and a second light emitting assembly. The base is disposed on a bearing surface. The first light emitting assembly is disposed in the base and has a first optical axis. The second light emitting assembly is disposed in the base and has a second optical axis. A distance between the firs optical axis and the second optical axis is D. An inner edge of a first light source emitted by the first light emitting assembly and an inner edge of a second light source emitted by the second light emitting assembly intersect at a point on the bearing surface, thereby forming an irregular-shaped sensing region having a boundary passing through the point. A length of a shortest side of the irregular-shaped sensing region is less than or equal to 2D.

    Abstract: A projection device includes a projection module and a first camera module. The projection device has a first optical axis and configured to form a projection area, wherein a projection of the first optical axis on an X-Z plane of the projection device is perpendicular to an X-Y plane on which the projection area is formed. The first camera module is disposed on a side of the projection module and includes a second optical axis, wherein the first camera module is configured to form a first shooting area, the second optical axis forms a first angle Δθ1 with respect to the first optical axis, the projection area at least partially overlaps the first shooting area to form an overlapping area, and the first angle Δθ1 is a function of a distance between the projection module and the first camera module.
