Abstract: Techniques pertaining to seamless switching control for foldable or flip devices are described. A processor implemented in a multi-display apparatus having a primary display and a secondary display executes a status change with respect to the primary display and the secondary display by: (1) maintaining a power supplied to the secondary display during the status change; and (2) switching the primary display and the secondary display from a first state to a second state.

Abstract: An interactive learning system and method is provided. The interactive system includes a camera device and an interactive device. The camera device executes a functional operation, and transforms the functional operation into executive information. Then, the camera device transmits the executive information to the interactive device. The interactive device generates guiding information for guiding a user to operate the camera device according to model information of the camera device, and transmits the guiding information to the camera device so as to control the camera device to execute a guiding operation related to the guiding information.
