Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is described in further detail.Should be appreciated that detailed description of the invention described herein is only in order to explain this
Bright, do not limit protection scope of the present invention.
Traditional remote-pointing device, including handheld terminal, this handheld terminal is the terminals such as hand-held pen, as in figure 2 it is shown, the present invention
Remote-pointing device also include transmitting terminal and receiving terminal.
Described transmitting terminal includes that light source and encoder, described receiving terminal include optical pickocff and processor;Described coding
Information waiting for transmission is encoded by device, makes described light source send the light of character pair, and described optical pickocff gathers described light
The light that source sends, the light of optical pickocff collection is decoded by described processor, obtains information waiting for transmission.
The handheld terminal of remote-pointing device with target device as the two ends communicated, between information waiting for transmission, it may be possible to
Unidirectional, it is also possible to two-way.If unidirectional, then use a pair transmitting terminal and receiving terminal, if two-way, then exist
The two ends of communication each arrange a transmitting terminal and a receiving terminal.
As it has been described above, the different characteristic that this equipment uses light source reacts information waiting for transmission, the feature of light source can be bright
Go out, light and shade, color, frequency, polarization direction, number how many, or the combination of various feature etc..
If information waiting for transmission is the bearing data of " upper and lower, left and right " or more direction, then light source can be set to
Multiple luminescent devices various directions arrangement, if certain bearing data waiting for transmission be " on ", then would indicate that " on " luminescence
Device is lighted, and other luminescent devices keep the state not worked.The optical sensor of receiving terminal is clapped preferably by photographic head, photographic head
Taking the photograph light source picture, processor resolves picture, draw information " on ", and transmit the main frame to target device, main frame adjusts on screen
Cursor, complete point operation.
If information waiting for transmission is to have significant numerical data, then light source can be set to the list of multiple luminescent device
Arranging in direction, according to binary system, the light source of the correspondence position to 0 and 1 is with the characteristic luminescence of difference.Alternatively, it is also possible to use non-
The arbitrary carry system forms such as binary system, as long as light source can have same multiple significant condition.
If information waiting for transmission is to have significant key assignments on handheld terminal, then light source can be set to multiple luminescent device
Light and shade sequence indicate the state that different key on handheld terminal is pressed and lifts, reach to control target by handheld terminal with this
The purpose of equipment.
This remote-pointing device is explained further below with an application example.
The main frame of target device has several state, for instance in dormancy, sleep or off-mode, if now handheld terminal still to
Main frame sends information, it will sends unsuccessfully, in order to avoid this situation, the state of main frame is led to as the one of information to be transmitted
Know handheld terminal, in order to make handheld terminal Stop message send, saves energy.In order to realize this purpose, following scheme can be used:
The main frame of target device arranges transmitting terminal, and handheld terminal arranges receiving terminal.000 representative master preset by the encoder of transmitting terminal
Machine dormancy, 001 represents main frame sleep, and 011 represents main frame is in holding state, and 010 represents main frame in running status.Light source is by 4
Individual Light-Emitting Diode rearranges, lamp on the basis of first lamp, and its excess-three lamp is signal lights.
When main frame enters holding state, controlling first lamp bright, second lamp goes out, and the 3rd lamp is bright, and the 4th lamp is bright
Continue 15ms.The photographic head of receiving terminal is a cycle to take pictures light source with 10ms.The processor of receiving terminal, passes through image
Process the hot spot and hot spot distance identified in photo, according to default rule, identify the instruction of 011, and learn that main frame enters
Standby mode, and then draw oneself up also into energy saver mode.
Communication means between remote-pointing device of the present invention and target device, as it is shown on figure 3, include step:
Step S101, communication one end, information waiting for transmission is encoded, makes light source send the light of character pair;
Step S102, at the other end of communication, gather the light of light source and be decoded, obtaining information waiting for transmission.
Described remote-pointing device as the two ends communicated, carries out unidirectional or two-way communication with its target device.
As a preferred embodiment, the feature of described light source includes light on and off, light and shade, color, frequency and polarization direction.
As a preferred embodiment, described light source is multiple, and multiple described light sources carry out light on and off arrangement, forms reflection
The binary digit of information to be transmitted.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
