It should be noted that the keyboard device of the present invention can be used in the financial field, such as a bank automatic teller machine and a bank automatic card transaction, and can also be used in any field other than the financial field. The application field of the keyboard device is not limited by the utility model.

The keyboard apparatus 910 according to the embodiment of the present invention will be described in detail with reference to fig. 2 to 4 based on the scenario described in fig. 1.

Fig. 2 schematically shows a schematic view of a keyboard apparatus according to an embodiment of the present invention in an inactive state. As shown in fig. 2, the keyboard apparatus includes a key projector 1 and a key sensing member 2.

According to an embodiment of the present invention, the key projector 1 is disposed above the input area for projecting a plurality of key images below the input area. The input area is a space area where a user performs an input action, i.e., a space area from the key projector 1 to the key sensing component 2. As shown in fig. 3, when the keyboard apparatus is turned on, the key projector 1 projects a plurality of key images in the virtual keyboard below the input area. The key images projected by the key projector 1 may be distributed in a manner that the key images are arranged in a line as shown in fig. 5, or in a manner that the key images are arranged in a conventional password keyboard style as shown in fig. 6A. The key images may be arranged in sequence or in disorder.

Fig. 4 schematically shows a frame diagram of the key sensing assembly 2 according to an embodiment of the present invention, and as shown in fig. 4, the key sensing assembly 2 includes a plurality of sensors 21, a plurality of timers 22, a selector 23 and a voice reminder 24.

According to the embodiment of the present invention, the plurality of sensors 21 are disposed at the projection positions of the corresponding key images, and are in one-to-one correspondence with the key images, and are used for detecting the input actions of the user. According to an embodiment of the present invention, the sensor 21 may be a photosensitive sensor that detects an input action when the photosensitive sensor cannot detect light projected by the key projector 1. The sensor 21 may be a heat-sensitive sensor that detects an input motion when the proximity of a finger is detected. For example, when the sensor 21 is a photosensitive sensor, when the user's hand blocks the light projected to the sensor 21 by the key projector 1, the user input action is detected; when the sensor 21 is a thermistor, the user input action is detected when the sensor 21 detects heat caused by the approach of a finger. Preferably, the present invention does not limit the type of the sensor 21, for example, the sensor 21 may also use a laser ranging, a sound ranging, a computer vision, etc. to achieve the recognition effect of detecting the input action of the user.

According to the embodiment of the present invention, a plurality of timers 22 are respectively connected to the sensors 21, and are configured to count time when the sensors 21 detect an input action, and generate a key signal when the counted time exceeds a predetermined time. For example, in the case of the key image distribution shown in fig. 5, the sensor 21 is a photosensitive sensor, the timer 22 may have a predetermined time of 2 seconds, when the user's finger blocks the sensor 21 corresponding to the key image "1", the timer 22 counts time, and when the counted time exceeds 2 seconds, the key signal "1" is generated. When the user has temporarily blocked the sensor 21 corresponding to the key image "5" before the finger blocks the sensor 21 corresponding to the key image "1", and the timer 22 corresponding to the sensor 21 does not count for more than 2 seconds, the key signal "5" is not generated.

According to the embodiment of the present invention, the selector 23 is connected to each timer 22, and is used for selecting the correct key signal by the selector 23 when a plurality of timers 22 count time, that is, when a plurality of sensors 21 simultaneously detect the input actions of the user. Since there is a sequence when the user blocks the key images from bottom to top, and the last block is often the user wants to input the key, in the embodiment of the present invention, when there are a plurality of timers 22 all timing, the selector 23 selects the sensor 21 that starts timing last to generate the key signal. For example, when the user needs to use a finger to block the sensor 21 corresponding to the key image "5", the hand moves from bottom to top to block the sensors 21 corresponding to the key images "0", "8", "9", "#", and "5", and finally blocks the key image "5". And because the user is required to hover over the key image "5" for more than the preset time, the timer 22 corresponding to "0", "8", "9", "a", "#" will also exceed the preset time, and thus a plurality of corresponding key signals will also be generated. At this time, the selector 23 selects the key signal "5" generated by the timer 22 which starts timing last from the plurality of key signals, and can input the key signal which the user really wants to input.

According to the embodiment of the utility model, the voice reminder 24 is connected with the selector 23. When the selector 23 selects the key signal, the key signal is broadcasted. When the input action of the user is not standard, the selector 23 cannot distinguish which timer 22 starts to time last, and the voice reminder 24 can also remind that the input is wrong and give a prompt of a correct input action.

In the embodiment of the present invention, when the sensor 21 detects an input action of a user, the timer 22 starts timing, and when the timing exceeds a predetermined time, a key signal is generated, and the voice reminder 24 broadcasts a corresponding key voice according to the key signal, and inputs the key signal into the display 920 of the operating system 900. When the plurality of sensors 21 simultaneously detect the input motion of the user, the correct key signal is selected by the selector 23 to be input into the display 920 of the operating system 900.

According to the embodiment of the present invention, the keyboard apparatus further includes a key panel 3, a peep prevention cover 31, and a key projector mount 11.

According to the embodiment of the utility model, the key panel 3 is arranged below the input area. The input area can also be understood as a space between the key projector 1 and the key panel 3. The key panel 3 includes a plurality of key windows 32 opened on the upper side of the key panel 3, and the sensors 21 are respectively disposed in the key windows 32. The distribution of the key windows 32 is the same as the distribution of the key image projections. Preferably, the depth of the key window 32 is increased, which can effectively prevent the user from habitually touching the key panel 3.

According to the embodiment of the utility model, the peep-proof cover 31 is arranged on the keyboard device. Key projector 1 may be disposed inside privacy shield 31. The peep-proof cover 31 is used for semi-wrapping the key panel 3 and the input area, so that peeping of other people can be effectively prevented.

According to the embodiment of the utility model, the key projector support 11 is used for erecting the key projector 1 above the input area, so that a user can conveniently adjust the projection position of the key graph. The key projector holder 11 may be disposed inside the peep preventing cover 31 as shown in fig. 2, or may be disposed on the key panel 3.

The specific operation method of the keyboard apparatus according to the present invention will now be further described with reference to the key image distributions shown in fig. 5 to 6C.

Usage scenario 1

When facing the special-shaped password keyboard shown in fig. 5, assuming that the user needs to input the password "123456", the sensor 21 of the keyboard device is a photosensitive sensor, and the preset time of the timer 22 is 2 seconds, the operation method of the keyboard device includes steps 101 to 103.

Step 101, the keyboard device is turned on, and the key projector 1 projects a plurality of key images.

When the keyboard device is turned on, the key projector 1 projects a plurality of key images, which are distributed as shown in fig. 5.

Step 102, the user extends the hand above the key image for a period of time until the voice reminder 24 issues a reminder.

When the user needs to input "1", the light reaching above the key image "1" blocks the light of the key projector 1, so that the corresponding sensor 21 detects the input action. The user keeps blocking for more than 2 seconds by hand until the voice reminder 24 sounds a prompt tone of "1" or "tic", the user stops blocking and checks whether the entered number is correct.

And 103, repeating the step 102 until all passwords are input.

The remaining "23456" s are all entered according to the method shown in step 102.

Usage scenario 2

In the case of the conventional password keypad as shown in fig. 6A to 6C, assuming that the user needs to input the password "054321" and the sensor 21 of the keypad device is a light-sensitive sensor, and the preset time of the timer 22 is 2 seconds, the operation method of the keypad device includes steps 201 to 203.

Step 201, the keyboard device is turned on, and the key projector 1 projects a plurality of key images.

The keyboard device is turned on, and the key projector 1 projects a plurality of key images, which are distributed as shown in fig. 6.

Step 202, the user extends the hand above the key image and continues for a period of time until the voice reminder gives a reminder.

As shown in fig. 6A, when the user needs to input "0", the user extends a hand above the key image "0" to block the light of the key projector 1, so that the corresponding sensor 21 detects the input action. The user keeps blocking for more than 2 seconds by hand until the voice reminder 24 sounds a prompt tone of "0" or "tic", the user stops blocking and checks whether the entered number is correct.

As shown in fig. 6B, when the user needs to input "5", the user extends the hand from bottom to top to the top of the key image "5" to block the light of the key projector 1 for more than 2 seconds. At this time, the selector 23 selects "5" which is finally blocked as the correct key signal to output. When the user hears the voice reminder 24 to emit a "5" or "tic" tone, the user checks whether the entered number is correct.

As shown in fig. 6C, although it is difficult to simultaneously block "4" and "5" with the user's hand in practical situations due to the limitation of the peep-proof cover 31. However, if the user needs to input "4", so as to block "4" and "5" at the same time, and the selector 23 cannot judge which of the corresponding timers 22 started to time last, the voice reminder 24 issues a warning sound of "input error". The voice reminder 24 can also explain the reason that the user cannot recognize and introduce recommended operation gestures in a voice broadcasting mode after sending out multiple times of 'input error' prompt tones, so as to help the user input.

And step 203, repeating the step 202 until all passwords are input.

All digits are entered according to the method shown in step 102.

The utility model provides a contact-free keyboard device, so that a user does not need to touch a key panel for operation, and the risk of virus cross infection is greatly reduced. In addition, in order to prevent the false touch, the present invention may adopt the distribution mode of the special-shaped key image as shown in fig. 5 to reduce the probability of the false touch of the user, and may also use the selector 23 to select the correct key signal.
