the processor is configured to acquire the UWB signal, determine, according to the UWB signal transmitted at the different time, location change information of the tag device at the different time relative to the electronic device, and adjust a target object in the electronic device according to a specific coefficient and the location change information of the tag device;
and the display equipment is used for displaying the scene image containing the target object so as to realize real-time interaction between the target object and the interactive object corresponding to the label equipment.
Here, the display device may be a display in the electronic device, or may be a projection device in the electronic device. Of course, a separate device, such as 3D glasses, is also possible.
In a general communication system, a high-frequency carrier is used to modulate a narrow-band signal, and the actual occupied bandwidth of the communication signal is not high. UWB, in contrast to conventional communication technology, achieves wireless transmission by transmitting and receiving extremely narrow pulses having a nanosecond or microsecond order or less. Due to the extremely short pulse time width, ultra-wideband over the spectrum can be achieved, using bandwidths above 100MHz (megahertz), even up to 500 MHz.
That is, this technique achieves fast data transmission at a low power consumption level through an ultra-large bandwidth and low transmission power. Since the time width of the UWB pulse is extremely short, the distance measurement can be performed with high-precision timing. Compared with Wi-Fi (wireless Internet access) and Bluetooth positioning technologies, UWB has the following advantages: the anti-multipath capability is strong, and the positioning precision is high; the timestamp precision is high; the electromagnetic compatibility is strong; the energy efficiency is high.
Currently, there are three types of commonly used UWB ranging methods, which are:
(1) TOF (Time Of Flight, Time Of Flight method): ranging is achieved by measuring the time of flight of the UWB signal between the base station and the tag.
(2) TDOA (Time Difference Of Arrival method): the time difference of the UWB signals from the tags to the base stations is used for positioning.
(3) PDOA (Phase Difference Of Arrival Phase Difference method): and measuring the azimuth relation between the base station and the tag by using the arrival angle phase.
Based on this, the embodiment of the present application provides a UWB-based screen operation scheme, where an electronic device of the scheme has a UWB device and can implement functions such as ranging and angle measurement. And the electronic device has a display device including, but not limited to, a display screen, a projection, glasses, and the like.
A portable device, such as a glove, cell phone, handle, etc., is in communication with the electronic device, the portable device having a UWB tag thereon.
And, the screen of the electronic device has one or more objects. When starting, such as pressing a button of a portable device, etc., the electronic equipment captures the position movement of the portable device through the UWB technology and converts it into the operation and movement of the object in the picture.
The electronic device captures the position movement of the portable device through UWB technology, which can be realized by the following modes:
taking a vertical plane as an example, fig. 5 is a schematic diagram of the portable device moving on the vertical plane according to the embodiment of the present disclosure, as shown in fig. 5, when the portable device 501 moves from the position a to the position B, the electronic device 502 can calculate the moving distance of the portable device 501 through two angle measurement. The distance measured twice is L1And L2The angle measured twice is theta1And theta2The included angle theta can be obtained by the difference of two angle measurements, so that the distance L of the vertical plane movement is obtained through the mathematical relationship of the triangley。
Similarly, the moving distance L from the horizontal planex。
FIG. 6 shows an object in a screen according to an embodiment of the present applicationThe movement diagram is, as shown in FIG. 6, scaled by a certain coefficient, the distance M that the object 61 needs to move on the horizontal plane in the screen 60 of the electronic devicey＝λ*LyThe distance M that the object 61 needs to move on the vertical plane in the screen 60 of the electronic devicex＝α*Lx. That is, the object 61 is expressed by M in the electronic device control screenx、MyTo effect movement of the object 61 from position C to position D in the screen 60.
In the embodiment of the application, the angle measurement and ranging based on UWB can operate the picture of the electronic equipment when the portable device moves, and the interaction with the content picture of the electronic equipment is realized. Therefore, the UWB-based screen operation scheme provided by the embodiment of the application can be used for screen operation, particularly motion sensing games and the like.
