Abstract: The present application relates to the technical field of projection devices, and in particular to a projection device comprising a base, a support bracket, and a projector body connected in sequence, wherein the projector body comprises a housing assembly, and the housing assembly is provided at an outer surface with a storage groove that accommodates and is adapted to the support bracket, and the support bracket is rotatably connected to the projector body within the storage groove. The rotatable connection between the support bracket and the projector body can realize the storage and the protection of the projector body, and the storage groove provided on the outer surface of the housing assembly can completely store the support bracket, which allows the projection device to have further reduced space occupancy after being stored, thus enabling a simple overall storage structure and a good storage effect.

Abstract: Provides are a method and device for synchronizing haptic feedback and visual feedback, so as to synchronize the haptic feedback accompanying a touch operation of a user and the visual feedback. The method includes: acquiring a tangential speed of rotation of a contact, the contact is generated when a user executes a touch operation of rotation within a coverage range of a virtual knob displayed on a touch screen, the touch operation being accompanied by haptic feedback; controlling response labels displayed on the touch screen to move in sequence according to the tangential speed to synchronize the haptic feedback and visual feedback formed by moving response labels, a step length of movement of each response label corresponds to a preset unit angle, and the number of movements of each response label is determined according to the number of preset unit angles encompassed in a rotation angle of the virtual knob.

Abstract: Provided are a haptic feedback control method, a haptic feedback control device, and a storage medium. The haptic feedback control method includes: controlling a display screen to display an adjustment information page having a touch adjustment button and a three-dimensional (3D) model of a vehicle seat upon receiving an instruction to display the page on the display screen, where the display screen has a vibration sensor; and receiving a touch instruction, on the touch adjustment button, from a user, adjusting a posture of the vehicle seat through the touch adjustment button, controlling the vibration sensor to perform haptics at a position of the touch adjustment button, and controlling the display screen to synchronously display a posture of the 3D model of the vehicle seat that is the same as that of the vehicle seat.

Abstract: A photographing device support having an auxiliary handle includes: a telescopic support body, a connecting apparatus, and a clamping apparatus; and an auxiliary handle for an operator to grip, one end of the auxiliary handle is provided with a hinge joint, and the auxiliary handle is up-and-down rotatably connected to the connecting apparatus by the hinge joint, the hinge joint is provided with a first convex platform, and the connecting apparatus is provided with an elastic locking piece, the elastic locking piece cooperates with the first convex platform, so that when the auxiliary handle rotates downwards to fold relative to the telescopic support body, the elastic locking piece is elastically deformed at first to enable the first convex platform to rotate upwards and cross over the elastic locking piece, and then is reset to prevent the first convex platform from rotating back, so as to lock the auxiliary handle.

Abstract: The present disclosure relates to a display system, an operation feedback method, an electronic device and a storage medium. In an embodiment of the present disclosure, the display system includes a processor, and a display screen configured to display a Graphical User Interface (GUI) control. The processor is configured to: determine operation attribute information of a touch operation performed by a user on the GUI control displayed on the display screen; and generate, based on the operation attribute information, a haptic feedback.
