Specific orientation is operated with specific orientation construction, should not be understood as limitation of the invention with this.
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Embodiment one
As shown in Figure 1, including the following steps S10~S50 the present embodiment provides a kind of feedback method of projected keyboard.
S10: each laser key of projected keyboard is projected using the projector 1.
Specifically, the projector 1 can project the light of different colours, and specifically, the projector 1 can project red, white, blue
Perhaps the single projected keyboard of the color of the various colorss such as green, which also can according to need to project, is provided simultaneously with two kinds or more
The projected keyboard of color, such as the laser key such as F1~F12 of projected keyboard is red, and the laser of 26 English alphabets is pressed
The color of key is then blue etc..
S20: by a wordline sexuality stress shaven head 2 each laser key top projection induction light beam, incude light beam
For forming hot spot on the object of striking laser key.
Specifically, a wordline sexuality stress the light beams of 2 transmitting of shaven head can to form light in the top of laser key flat
Face, as long as the objects such as finger pass through the optical plane striking laser key, induction light beam will because of being blocked by objects such as fingers and
Hot spot is left on the objects such as finger.
S30: being tracked hot spot using camera 3, thus the laser key that confirmation is pressed.
Specifically, the technology for carrying out visual pursuit using camera 3 is quite mature, and this embodiment is not repeated.Example
Such as there is hot spot above laser key " C ", then system determines: " C " of projected keyboard is pressed.Such as " C ", " O ",
Successively there is hot spot in the top of " D ", " E ", then system determines: user has input word " CODE ".
S40: after the laser key of projected keyboard is by striking, become the visual effect by the laser key of striking
Change.
Specifically, visual effect variation has very much, such as color change, the size of laser key of laser key become
Change, the shape of laser key changes (such as sectional view becomes round from rectangle), the text hair on laser key
Changing (such as becoming smiling face etc. from original " A ").
In this present embodiment, S40 includes:
S401: when projected keyboard laser key by striking before, make all laser keys that the first color be presented；
S402: when the laser key of projected keyboard is by striking, make that the second color is presented by the laser key of striking；
S403: after the laser key of projected keyboard is by striking, make to restore the first color by the laser key of striking.
For example, for example:
1. just start, the projector 1 projects a keyboard, and the laser key on keyboard is entirely red；
2. laser key " C " becomes blue when the finger striking laser key " C " of user；
3. laser key " C " restores red after the finger of user leaves laser key " C ".
Specifically, change by such visual effect, the color change that user can directly stare at keyboard is known that certainly
Whether oneself input has obtained effective response and identification, it is not necessary to toggle between screen and keyboard again, thus greatly
Improve input efficiency.
S50: the corresponding input content of laser key being pressed is fed back into host 6.
Specifically, laser key is not true physical button, so laser key after striking, is first had to determination and touched
The laser key hit is corresponding with which instruction, and the instruction is then sent to host 6 again.For example, in projected keyboard work,
Backstage also will start a dummy keyboard program associated with host 6, the virtual key of dummy keyboard and swashing for projected keyboard
Light key corresponds, and after laser key is by striking, can be defaulted as clicking from the background corresponding with by the laser key of striking
Virtual key, therefore, the available corresponding feedback of host 6.
Embodiment two
The difference of the present embodiment and implementation one is step S40, and in this present embodiment, step S40 includes:
S401: when projected keyboard laser key by striking before, make all laser keys that the visual effect of protrusion be presented；
S402: when the laser key of projected keyboard is by striking, make the vision effect for being presented to sink by the laser key of striking
Fruit；
S403: after the laser key of projected keyboard is by striking, make the vision effect for being restored protrusion by the laser key of striking
Fruit.
For example, for example:
1. just start, the projector 1 projects a keyboard, and the laser key on keyboard is entirely protrusion；
2. laser key " C " becomes to sink, seemingly by finger down one when the finger striking laser key " C " of user
Sample；
3. laser key " C " restores raised position after the finger of user leaves laser key " C ", seemingly bounce again
Equally.
Specifically, the present embodiment is suitable for the case where projection of laser key is three-D pattern, is pressed by making
Laser key generate sink visual effect carry out the truth that can sink when analog physical key is pressed, can greatly mention
High user experience.Preferably, each laser key can be saved in projected keyboard in advance and switches to sinking shape from raised position
State and the floating animation that raised position is switched to from sinking state are just thrown when then some laser key is discharged by striking
Penetrate the floating animation raised again that first sinks corresponding with the laser key.
