Embodiment 1
[0030] In the embodiment of the present application, a writing device is described.
[0031] Specifically, the writing device can be used in the electronic device in the embodiment of the present application to realize air input. Of course, the writing device is specifically a device with a writing function.
[0032] The writing device includes a writing end, an erasing end, and a writing body between the writing end and the erasing end.
[0033] The writing end is provided with a first reflecting device, and the first reflecting device can correspondingly reflect N signals emitted by the N range finders in the electronic equipment back to the N range finders.
[0034] The erasing end is provided with a second reflecting device, and the second reflecting device can correspondingly reflect the N signals emitted by the N range finders back to the N range finders.
[0035] In the embodiment of the present application, the writing device uses a whiteboard marker with a writing f...
Embodiment 2
[0076] In the embodiment of the present application, an electronic device is described.
[0077] Specifically, the electronic device includes a display screen 303, N range finders, and a signal processor. Wherein, N≥3 and is an integer.
[0078] Specifically, N range finders are arranged at different positions of the display screen 303, and are used to transmit electromagnetic wave signals to the writing device, so as to obtain N first distance parameters between the N range finders and the writing end of the writing device, and N second distance parameters between the N range finders and the erasing end of the writing device are obtained.
[0079] The signal processor is configured to analyze N first distance parameters and N second distance parameters to obtain a first spatial distance between the writing end and the display screen 303 and a second spatial distance between the erasing end and the display screen 303 .
[0080] Further, the signal processor is connected betw...

Abstract
The invention discloses an electronic device and a writing device. The electronic device comprises a display screen, N rangefinders and a signal processor. The rangefinders are arranged at different positions on the display screen, and are used for emitting electromagnetic signals to the writing device to obtain N first range parameters between the N rangefinders and the writing end of the writing device and to obtain N second range parameters between the N rangefinders and the erasing end of the writing device. N > / =3, and N is an integer. The signal processor is used for analyzing the N first range parameters and the N second range parameters, and obtaining a first space range between the writing end and the display screen and a second space range between the erasing end and the display screen.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a writing device. Background technique [0002] At present, with the development of electronic technology, there are more and more information input methods in human-computer interaction, such as key input, touch screen input, mouse input, etc. Electronic devices designed based on these interactive methods , It is also applied in education, technology and other fields. [0003] The following are some examples of equipment used in the field of education. [0004] The first type: wall-integrated interactive electronic whiteboard. [0005] The wall-integrated interactive electronic whiteboard is composed of a writing operation screen and a large-screen display panel. The writing operation screen is located on one side of the large-screen display panel, and is composed of a touch screen, a controller, a display, a large-screen display or a projector, a...
