Detailed ways

Referring to Fig. 3 below, the present invention is connected to an electronic device 16 with a display screen, and includes a remote control device 18, wherein the electronic device 16 is a device with a global positioning system (GPS), a mobile phone, a TV, a notebook Computer, portable video player, or e-book. The remote control device 18 mainly includes a motion sensor 20 , a microprocessor 22 and a first radio frequency transmitter 24 , and the motion sensor 20 is connected to the microprocessor 22 and the first radio frequency transmitter 24 in sequence. The movement sensor 20 detects its own movement, and outputs at least one movement parameter accordingly, and the movement parameter is at least one of a distance parameter, a direction parameter and a speed parameter. The microprocessor 22 then receives the movement parameters, and thereby outputs a movement display instruction wirelessly through the first radio frequency transmitter 24 . In addition, the present invention further includes a second radio frequency transmitter 26 connected to the electronic device 16 , which is not included in the remote control device 18 . The second radio frequency transmitter 26 can receive the mobile display command output from the first radio frequency transmitter 24, so as to output the mobile display command to the electronic device 16, and then use the mobile display command to shift or shift the browsing page of the display screen accordingly. zoom. Certainly, the second radio frequency transmitter 26 can be built into the electronic device 16 to perform the above actions.

In order to effectively control the shifting and zooming of browsing pages, the remote control device 18 further includes a timer 28 connected to the microprocessor 22 and a first and second control keys 30 , 32 . The timer 28 has a preset interrupt time, since the microprocessor 22 receives the same movement parameter, and after the above-mentioned interruption time, if the microprocessor 22 no longer receives new movement parameters, it will interrupt the output corresponding to the above-mentioned A mobile display directive with the same mobile parameter to fix the browse page. In addition, if you want to shift the browsing page, you must first activate the first control key 30, and then the microprocessor 22 will output a moving display command according to the moving parameter to control the corresponding shifting of the browsing page on the display screen. For example, when the mobile sensor 20 is tilted forward, backward, left, and right respectively, the browsing page is shifted up, down, left, and right respectively, and the larger the tilting angle of the mobile sensor 20 is, the more the browsing page is shifted. The faster the speed. And when wanting to zoom in and out of the browsing page, the second control key 32 must be activated first, and then the microprocessor 22 will output a moving display command according to the moving parameter, so as to control the browsing page of the display screen to zoom in accordingly. For example, when the mobile sensor 20 tilts forward and backward respectively, the browsing page is zoomed in and out respectively; 20 The larger the inclination angle is, the faster the zooming speed of browsing pages is. Using the above-mentioned intuitive control method, you can easily browse various positions on the page, which is a great boon for users who are not familiar with the operation method of the screen, such as the elderly.

The remote control device 18 can also communicate with the electronic device 16 two-way. The remote control device 18 further includes a sound player 34, such as an earphone or a loudspeaker, and the sound player 34 is connected to the first radio frequency transmitter 24. , the electronic device 16 synchronously and sequentially transmits a sound signal to the sound player 34 through the second and first radio frequency transmitters 26 and 24 for playing.

Please refer to FIG. 3 and FIG. 4 below, as shown in the figure, wherein the sound player 34 is an example of a loudspeaker; the browsing page is an example of an electronic map. When the user activates the first control key 30 and tilts the remote control device 18 to the left or right, the motion sensor 20 also tilts to the left or right, and the microprocessor 22 outputs For the movement parameters, the first and second radio frequency transmitters 24 and 26 output movement and display instructions to the electronic device 16 to shift the electronic map on the screen to the left or right. While shifting, the electronic device 16 transmits sound signals to the speakers through the second and first radio frequency transmitters 26 and 24 for playing, allowing the user to interact with the screen images. After the interrupt time of the timer 28, the microprocessor 22 will interrupt the output of the moving display command according to the signal received from the timer 28, so as to fix the electronic map at a certain position.

Then please refer to Fig. 3 and Fig. 5 at the same time, as shown in the figure, wherein the sound player 34 and the browsing page are also respectively exemplified by the speaker and the electronic map. When the user activates the second control key 32 and tilts the remote control device 18 to the left or right, the motion sensor 20 also tilts to the left or right, and the microprocessor 22 outputs the motion sensor 20 according to the For the movement parameters, the first and second radio frequency transmitters 24 and 26 output movement and display instructions to the electronic device 16, so that the electronic map on the screen can be enlarged or reduced respectively. While zooming, the electronic device 16 transmits sound signals to the speakers through the second and first radio frequency transmitters 26 and 24 for playback, allowing the user to interact with the screen images. After the interrupt time of the timer 28, the microprocessor 22 will interrupt the output of the moving display command according to the signal received from the timer 28, so that the electronic map is presented with a fixed magnification.
