Interactive projection device

The invention relates to an interactive entertainment device; in particular to an interactive projection device that can be remotely controlled via the Internet.

As technology continues to evolve, modern people can communicate and maintain more and more connected channels, such as social networking sites or mobile communications software, making modern people increasingly dependent on the use of smart mobile devices and network communication. The problem with the above situation is that the opportunities for face-to-face communication between people are greatly reduced, and the number of "lower heads" is constantly rising. This phenomenon is particularly common in dining occasions and in public places where crowds gather. For example, in the case of dining, it is often seen that the diners at the same table are not talking to friends at the same table, but are using each other. Their respective mobile devices hang around their respective online worlds. Even when three or five friends gather at a sightseeing spot or a rest table in a park, the first thing is to pick up the mobile device and ignore the opportunity to communicate with friends around.

Therefore, there is a container disclosed in the foregoing, which can be placed on a table, such as a cup that can be projected as disclosed in the Chinese Patent Publication No. CN2754179Y, which can be pre-defined by the projection magnifying device and the pattern film in the handle. Projected on the desktop, not only can the manufacturer's promotional words be projected to achieve the advertising effect, but also allow users to increase the chance of looking up by discussing or researching such innovatively designed cups while using the cups. Increase interaction and communication between users.

However, the above-mentioned projection cup can only project the pattern film. The predetermined pattern or typeface on the single, so a single cup can only project a fixed pattern or typeface; accordingly, in order to introduce more innovative interactive products, the inventor of the present invention proposed a projection device that can interact with the user, so that When users gather together, they can have more interaction through the device, which adds fun and draws closer to each other.

In view of the above, an object of the present invention is to provide an interactive projection device, which not only has a projection function, but also allows a user in the vicinity or the far end to control various information projected by the interactive projection device by using his own mobile device. Interesting interactions that enhance the emotions between people.

In order to achieve the above object, the interactive projection apparatus provided by the present invention comprises at least one pico projector and a transceiver. The pico projector includes a memory, a processor and a projection unit; the memory stores an image data; the processor is electrically connected to the memory and the projection unit for reading the memory The image data is controlled according to the image data to control the projection unit to project the corresponding image. The transceiver is electrically connected to the processor and stores an identification message; the transceiver transmits the identification message to an object through the Internet to interconnect the object with the transceiver. Thereby, when the object transmits the external signal, the transceiver receives the external signal and transmits the external signal to the processor; after receiving the external signal, the processor interprets the external signal to obtain the other Image data, and the other image data is transmitted to the memory to replace the image data stored in the memory.

The effect of the invention is to use the transceiver, the processor and the memory, so that the user can input the image to be displayed into his own mobile device and convert it into an external signal, so that the pico projector can project the image. It is not limited to the predetermined pattern or typeface of the pattern film contained in the previously castable cup. In addition, through the Internet, the interactive projection device can interact with at least An object is interconnected, and an external signal is transmitted by the object to remotely control an image projected by the interactive projection device.
