An unmanned store is provided. The unmanned store includes a projection device, a rotation device, a functional keypad, and a control system. The projection device may project a virtual image to a real space of the unmanned store; the rotation device is connected to the projection device, and is configured to drive the projection device to rotate such that the virtual image moves in the real space; the functional keypad includes a functional key, and may send a key signal to a control system in response to the functional key being pressed; upon receiving the key signal, the control system switches the commodity information displayed by the projection device based on the key signal.

A projection system and a projection method are provided. The projection system includes a projection device, a streaming device, and a control device. The projection device includes a first image input port and a second image input port. The streaming device is electrically connected to the first image input port of the projection device and is coupled to the projection device in a detachable manner. The control device is communicatively connected to the streaming device. The control device transmits a first command signal to the streaming device, so that the projection device projects image data from the streaming device. The projection method may be executed by the projection system. The projection system and the projection method of the disclosure provide a user with more convenient operation environment and operation interface.

A ceremonial occasion video display device and a ceremonial occasion building capable of making more-ingeniously-planned innovative impressive production in a ceremony for a ceremonial occasion. A character projected onto a display region of a display member representing the shape of an opening book freely moves around on right and left pages for a while, and thereafter, starts such action that the character turns over a second page with the character holding a right end of the second page. On the display region after the second page has been turned over, other pictures as next pages are projected as if the character turns over the page of the book. Specifically, part of a third page is projected onto the display region at a position on the back side of the second page, and part of a fourth page is projected onto the region after the second page has been turned over.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate augmented-reality features such as projecting assistive visual elements or virtual UI elements into an operational area. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.
