Description

Virtual book page turning display device

Technical Field

The utility model relates to a human-computer interaction technical field, concretely relates to virtual book turns over book display device.

Background

The development of virtual reality and augmented reality technologies promotes the continuous expansion of the application field of virtual book display, and the virtual book display is applied to various occasions such as exhibition halls, movie and television advertisements, teaching interaction and the like. The virtual book content is viewed through equipment such as a projector, a camera and an induction device, and interactive behaviors such as page turning, virtual book image and text viewing, video and audio clicking playing and the like are achieved. Compared with the traditional book, the display content is richer, the covering content is wide, the space resource is saved, and the impression of a viewer is profound. The existing virtual book display method and device are generally of two types, one is that the virtual book content is displayed through a touch screen, and page turning display of the virtual book content is achieved through touch. The other mode is that the page turning and related display are realized by projecting and displaying through a projector and acquiring the hand waving action of a user in an infrared induction mode.

In the prior art, a virtual book is displayed through a touch screen and projected through a projector, so that the most natural book turning action of human beings cannot be simulated when a user turns the book, and the experience sense of reality is not strong. Therefore, a virtual book flipping display device capable of providing a real page flipping experience to a user is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a virtual book that can bring for the user really turns over the book experience turns over the book display device.

In order to achieve the above object, the main technical solution of the present invention is to provide a virtual book page turning display device, which includes a host, an entity book with page marks, a reader for reading the page marks, and a projector for projecting a projection picture on the entity book, wherein both the projector and the reader are in communication connection with the host; the reader feeds back the read page identification information to the host; the host generates a projection picture according to the page identification information and feeds the projection picture back to the projector; the projector projects the projection picture on the physical book.

Preferably, the page identifier is an RFID tag storing information such as pictures and/or words.

Further, the page identification is an RFID tag storing information such as video/audio.

Furthermore, the page identifications of any two pages in the physical book are different. The page identification of each page is the same as the corresponding page content of the virtual book.

Furthermore, the system also comprises sound equipment, and the sound equipment is in communication connection with the host.

Further, the book reader comprises a detector for detecting whether a person approaches the physical book, and the detector is in communication connection with the host. The detector is used for determining whether a user exists in a preset range outside the physical book, when the fact that the user does not exist in the preset range outside the physical book is determined, the host feeds back the projector to output a preset default image on the physical book, and when the fact that the user exists in the preset range outside the physical book is determined, the host feeds back the projector to output a page image of the virtual book to be projected onto the physical book.

Further, the detector is an infrared sensor or an ultrasonic sensor.

Preferably, the reader is an RFID receiver.

The utility model has the advantages that:

(1) the physical book is used as a projection carrier, the projector projects the virtual book image onto the physical book, and the user can see the content of the virtual book on the physical book, so that the user is provided with real reading experience, and the interaction effect is strong;

(2) the integrated design is adopted, the structure is simple, the design is novel and reasonable, and the realization is convenient.
