The user inputs interaction information by scanning the two-dimensional code on a mobile terminal; a communication unit, disposed in the receiving space, connected to the mobile terminal, and configured to receive the interaction information input by the user on the mobile terminal; and a control unit, disposed in the receiving space, connected to the projection unit, the moving unit, the image acquiring unit, the interaction unit, and the communication unit, and configured to control, based on the interaction information of the communication unit, the input information of the interaction unit and the image information of the image acquisition unit, the projection unit to project the content and the moving unit to move.
One or more embodiments are illustrated by way of example, and not by limitation, in the figures of the accompanying drawings, wherein elements/modules and steps having the same reference numeral designations represent like elements/modules and steps throughout. The drawings are not to scale, unless otherwise disclosed.
The present disclosure is further described with reference to some exemplary embodiments. The embodiments hereinafter facilitate further understanding of the present disclosure for a person skilled in the art, rather than causing any limitation to the present disclosure. It should be noted that persons of ordinary skill in the art may derive various variations and modifications without departing from the inventive concept of the present disclosure. Such variations and modifications shall pertain to the protection scope of the present disclosure.
For better understanding of the present disclosure, the present disclosure is described in detail with reference to attached drawings and specific embodiments. Unless the context clearly requires otherwise, throughout the specification and the claims, technical and scientific terms used herein denote the meaning as commonly understood by a person skilled in the art. Additionally, the terms used in the specification of the present disclosure are merely for describing the objectives of the specific embodiments, and are not intended to limit the present disclosure. As used herein, the term “and/or” in reference to a list of one or more items covers all of the following interpretations of the term: any of the items in the list, all of the items in the list and any combination of the items in the list.
It should be noted that, in the absence of conflict, embodiments of the present disclosure and features in the embodiments may be incorporated, which all fall within the protection scope of the present disclosure. In addition, although function module division is illustrated in the schematic diagrams of apparatuses, and in some occasions, module division different from the divisions of the modules in the apparatuses may be used. Further, the terms “first”, “second”, and the like used in this text do not limit data and execution sequences, and are intended to distinguish identical items or similar items having substantially the same functions and effects.

In an embodiment, in this system, the image acquisition unit 40 is a camera. In the case that the image acquisition unit 40 acquires a person or an object, the interaction unit 50 is triggered, and a user may input information via the interaction unit 50, or the user may enter a relevant page by scanning the two-dimensional code of the interaction unit 50 on the mobile terminal, and input interaction information via the relevant page. Subsequently, the control unit 70 generates road guidance information based on destination information input by the user, and sends the road guidance information to the projection unit 20 to project the road guidance information. For example, road guide icons may be projected onto the ground to provide guide information for the user. Meanwhile, the control unit 70 may generate road moving information based on the information of the image acquisition unit 40, to control the moving unit 30 to drive the system to move, such that a specific person or object is guided to arrive at the destination. In the movable projection system, based on the interaction information input by the user, the projection unit is controlled to project the content and the moving unit 30 is controlled to drive the system to move, such that the user is guided in real time, and personalized guidance requirements are met.
