Abstract: A projection apparatus includes an image projection module, a lens module and a light emitting module. The image projection module has a first optical axis and forms a projection area on a bearing surface. A projection of the first optical axis on an X-Z plane is perpendicular to an X-Y plane on which the projection area is formed. The lens module comprises N cameras, each having a corresponding second optical axis and being for forming a shooting area. The N second axes are tilted to the first optical axis and have an angle with respect to the X-Z plane. The light emitting module includes M light emitting components, each having a corresponding third optical axis and being for forming a sensing area. The projection area, the N shooting areas and the M sensing areas are at least partially overlapped with each other to form a rectangular shooting sensing area.

Abstract: A portable electronic device and a control method thereof are provided. The method is adapted to a portable electronic device including a rotatable element, a fixed element, a screen, a processor, a switch module with at least two protruding elements, and fixed points. The rotatable element is nearby the fixed element. The protruding elements and the fixed points are facing to each other and configured at one and the other of the rotatable element and the fixed element. The processor is coupled to the switch module and the screen. The method includes to display a default user interface corresponding to a default mode on the screen, to determine a corresponding mode according to all press states of each protruding element in the switch module by the processor when the rotatable element is rotated due to an external force applied thereto, and to display a corresponding user interface on the screen.

Abstract: A portable electronic apparatus and an operation method of the portable electronic apparatus are provided. The operation method includes: sensing an angle of a cover relative to a base. The operation method often includes sensing a posture of the cover. In the operation method, a virtual operating function of an optical sensor is enabled based on the angle and the posture.

Abstract: A charger including a base and a clamping component is provided. The base includes a first charging portion and a second charging portion. The clamping component is connected to the base and aligned to the first charging portion and the second charging portion. A first charging space is formed between the clamping component and the first charging portion, and a second charging space is formed between the clamping component and the second charging portion.

Abstract: An assembled wearable electronic device including a first body and a second body is provided. The first body has a primary system and a first assembling portion. The primary system is for providing the independent operation of the first body and producing a related first data. The second body has a secondary system and a second assembling portion. The secondary system is for providing the independent operation of the second body and producing a related second data. The first body and the second body are adapted to be assembled to each other by the first assembling portion and the second assembling portion, and the first assembling portion and the second assembling portion are adapted to rotate relatively such that the first assembling portion is positioned or released by the second assembling portion.

Abstract: A foldable electronic device includes a first body, a second body and a hinge body. The hinge body is pivoted to the first body around a first pivoting axis and pivoted to the second body around a second pivoting axis so that the first body is able to rotate relatively to the second body. When the first body rotates to a first position relatively to the second body, a first front surface of the first body is closed to a second front surface of the second body on a closing plane, and a pivoting plane where the first pivoting axis and the second pivoting axis are located on and the closing plane are oblique to each other.

Abstract: An assembled wearable electronic device includes a first body, a second body and an engaging assembly. The first body has a primary system for providing the independent operation of the first body and producing a related first data. The second body has a secondary system and a fixing assembly. The secondary system is for providing the independent operation of the second body and producing a related second data. The engaging assembly is disposed at one of the first and second bodies. When the engaging assembly is located at a first position, the first and second bodies contact each other to be combined through the engaging assembly. When the engaging assembly moves to a second position, the first and second bodies are configured to be separated from each other. When the first and second bodies are connected to each other, the second data is read by the primary system.

Abstract: An electronic device is provided, which includes a display, a housing and a supporting structure. The display is disposed in the housing and a side of the housing opposite to the display has a storeroom. The supporting structure is disposed at the storeroom and has a flexible sheet, a first supporting-part and a second supporting-part. One end of the flexible sheet is fixed to the storeroom, the first supporting-part and the second supporting-part are respectively disposed at the flexible sheet, and the second supporting-part is bent relatively to the first supporting-part through the flexible sheet so as to provide the housing with a supporting force.
