Embodiments described herein include devices and methods for detecting a current form of a touch display unit of an electronic device. The current form includes one of a first form and a second form different from the first form. A relative position of a display layer of the touch display unit with respect to a touch layer of the touch display unit in the second form is different from the relative position of the display layer relative to the touch layer in the first form. The method also includes determining a first touch coordinate corresponding to a first touch operation. The method also includes acquiring a coordinate transformation associated with the current form of the touch display unit. The method also includes applying the coordinate transformation to the first touch coordinate to identify a corresponding first display coordinate and a display object corresponding to the first display coordinate.

Flexible display touch calibration

A display method and display device are described where the method includes when a first device is in a first status, the first device displays a first output content of the first device in a first display area of a display module, when it is detected that the first device goes into a second status from the first status, the first device displays the first output content in a second display area of the display module, and displays a second output content in a third display area of the display module, wherein, the first output content is different from the second output content, the second area does not overlap with the third area, and the first area contains the second and third areas.

Display method and display device

An electronic device, a processing method and a device are provided. The electronic device includes: a first and second display devices, an input device, a first component and a second component, a detection device configured to detect a relative position relation between the two components, a processing device is configured to control the first display device or the second display device in different cases to respond to operation data collected by the input device.

Electronic device, processing method and device

An electronic device and an information processing method are disclosed in the disclosure. The electronic device comprises: a wearable apparatus capable of forming a ring or an approximate ring, which is able to surround a first cylinder; a first sensor arranged at least partly in the wearable apparatus and towards an interior of the ring or the approximate ring, and configured to detect first biometric information of at least part of a wearer's body surrounded by the wearable apparatus if the wearable apparatus is worn on the part of the wearer's body; a first processor arranged in the wearable apparatus, and configured to determine whether the first biometric information matches first preset biometric information to obtain a determination result and to perform security processing corresponding to the determination result based on the determination result.

Electronic device and information processing method

An electronic apparatus and a display control method are described. The electronic apparatus includes a first display unit having a first visible part for displaying a first image; a first detecting unit for detecting a first parameter for indicating a relative distance between a target object and the first visible part; and a processing unit for generating an image to be displayed and for controlling the display of the first display unit according to at least the first parameter. When the first display unit is in a first state, if the relative distance is less than or equal to a threshold distance according to the first parameter, the processing unit controls the first display unit to switch from the first status to a second state, and the power consumption of the first display unit in the first state is lower than a power consumption in the second status.

Electronic apparatus and display control method

The present disclosure provides an electronic device and an information processing method. The electronic device comprises: a light emitter configured to emit lights; a sensor configured to acquire a first specified parameter which is formed based on a motion state or gesture of an operator; a processor configured to determine whether the first specified parameter meets a first preset condition, so as to obtain a first determination result, and configured to control the light emitter to emit the lights based on the first determination result at least in a case that the first specified parameter meets the first preset condition. The first preset condition comprises that the operator is performing a predetermined motion or is in a predetermined gesture.

A presentation system and method is disclosed, and the method includes the steps of: creating at least one buffer area in a first presentation device for at least one application; relocating the presentation-related data of a running application to the buffer area; and intercepting the presentation-related data from the buffer area and transmitting them to at least one second presentation device. With the above configuration of the present invention, the presentation-related data of various applications running in the host can be redirected as demanded by a user to a corresponding presentation device. With only one host, multiple application windows can be presented on multiple presentation devices at the same time.

Presentation system and method

A method for intercepting graphics device interface invocations by using filter driver which is transparent to graphics device interface engine and real display driver is disclosed. The method comprises steps of duplicating DDI function table returned from said real display driver, modifying DDI functions of said real display driver required for capturing screen update, creating auxiliary buffer area as updating buffer area for said screen update, and further processing said updating buffer area. With the method of the present invention, the support to video and 3D acceleration in the local computer can be realized by means of software, and the user can be provided with high-quality picture and display effect. Compared with the Mirror system in the prior art, since the present invention doesn't employ the Mirror system, the graphics device interface engine of the inventive system are not aware of the existence of the filter driver, the video and 3D acceleration function of the graphic card still remains. As a result, the function can be supported in the system, and applications employing video and 3D acceleration can be executed normally.

Method for acquiring graphics device interface invocation by using filter driver

A method for acquiring graphics device interface data and DirectX data by use of a filter driver transparent to transparent to a graphics device interface engine, DirectX kernel and a real display driver is disclosed, the method comprises steps of: updating the graphics device interface, and acquiring the graphics device interface data by use of a corresponding graphics device interface function in the filter driver; acquiring, for DirectDraw in DirectX, DirectDraw application and video update data by intercepting frame switch and bit block transfer operations of DirectDraw part; acquiring, for Direct3D in DirectX, data of Direct3D application by intercepting the update interface of Direct3D part. With the method of present invention, an integral acquisition of Windows GDI and DirectX data can be achieved while DirectX function remains available.

Method for acquisition of GDI and directX data

A method is provided for processing operation command in a computer that has a display and a host which includes a first display processing unit for local displaying and a second display processing unit for remote displaying.
