Example Embodiment

[0015] Example 1:

[0016] Such as figure 1 Shown is an ultrasonic electronic pointer of the present invention, including a pointer body with an ultrasonic signal transmitting function and a receiver that can receive the ultrasonic signal emitted by the pointer body and transmit the signal to the computer through a USB interface after processing; the pointer body A lithium battery 2 is provided on the computer to operate the OK button 7, the up button 8, the down button 5, the left button 4, and the right button 6, and an ultrasonic transmitter 3 for transmitting ultrasonic signals.

[0017] The above-mentioned ultrasonic electronic pointer is characterized in that the main body of the pointer has a built-in processor, a lithium battery 2 electrically connected to the processor, an ultrasonic drive circuit, and an ultrasonic transmitter 3 electrically connected to the ultrasonic drive circuit; the data receiver is built-in Ultrasonic receiver, an ultrasonic amplifier circuit electr...

Example Embodiment

[0018] Example 2:

[0019] Such as figure 1 Shown is the invention of an ultrasonic electronic pointer. The up button 8 is used to page up in the document presentation program; the down button 5 is used to page down in the document presentation program; the left The button 4 is used to go back in the video playing program; the right button 6 is used to move forward in the video playing program; the confirm button 7 is used to replace the enter key of the keyboard, which is suitable for all programs.

[0020] When in use, the demonstrator plugs the data receiver into the computer and installs the driver of the ultrasonic electronic pointer on the computer. When the main lithium battery of the electronic pointer is sufficiently charged, the demonstrator can control the computer through the buttons on the electronic pointer.
