It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The utility model is dedicated to the realization of finger recognition, that is, even if there is only one button, I can use five fingers to complete what I had five buttons before but only use one finger to complete.

The utility model is a new type of human-computer interaction device. The upper layer of its screen is a touch screen, the middle layer is a display screen, and the lower layer is a radio frequency antenna layer. On the one hand, the touch screen can collect the first type of contacts (the first type of contacts refers to Traditional common contacts), on the other hand, the newly added radio frequency identification device can help identify some second-type contacts with card information (the second-type contacts refer to new types of contacts that are different from ordinary contacts) . The device then submits the two types of contact information to the corresponding application and processes accordingly.

The working principle of the human-computer interaction device based on radio frequency identification provided by the utility model is as follows:

When the user clicks, the touch screen can accurately locate the position of the touch point, and send the position information to the host through the transmission line;

The host that gets the contact position information will send an instruction to turn on the antenna near the contact position to the Rfid reader through the transmission line, and turn on the two antennas near the contact position;

After the antenna is turned on, the reader starts to detect the card in the fingertip on the screen above the antenna, and saves the card information after detecting it;

Bind contacts and card information according to the principle of the closest time, and store the location information and card information of the contacts, which is called the second type of contacts;

After detecting a touch point of the second type, the human-computer interaction device will send the touch point information to a specific application program, and the application program will respond to the touch point, such as displaying card information at the touch point position.

The device utilizes radio frequency identification to open the reader-writer to scan the card information carried in the contacts while identifying the usual contacts, that is, to allow the contacts to carry the card information.

The contacts of the utility model can have modifiable card information. After specifying the specific information of the card corresponding to each finger, different fingers can be distinguished from each other, which enriches the human-computer interaction device. Gesture library; under the current trend that the number of buttons on smart phones is getting fewer and fewer but more and more functions, this utility model caters to this trend very well, only needs one touch key, and five fingers can click Five touch keys, one finger click equivalent.

In addition to the advantages described above, the utility model also has other features and advantages, such as increasing the types of operation gestures on the touch screen, and also being able to identify objects with labels on the screen by means of the device. The utility model will be described in further detail below with reference to the drawings.

The device includes a "Tmr" screen (that is, an interactive screen), a host, a Rfid reader, and a coordinator. The "Tmr" screen is composed of three layers: a touch screen, a display screen, and an antenna layer. We generally use an infrared touch screen for the touch screen, an ordinary LCD display screen for the display screen, and an antenna made by ourselves for the antenna. The specific structure is shown in Figure 3. The antennas on the antenna layer are placed side by side. These antennas can be rectangular made of wires. Each antenna is connected to a coordinator. The coordinator can match the reader and antenna to work better. , and then the coordinator connects the reader.

In the utility model, when the user clicks on the touch screen, the position information of the contact point is obtained; according to the position information of the contact point, the reader is controlled to open the antenna near the position of the contact point; when the antenna is turned on, the finger cot on the screen above the antenna is detected In the card information, when the card information is not detected, the contact is considered as the first type of contact; when the card information is detected, the contact is considered as the second type of contact; the detected card information and The second type of contact is bound, and the location information and card information of the second type of contact are stored. Among them, by binding the detected card information to the second type of touch point, different fingers of different people can be distinguished from clicking on the frequency screen at the same time.

In order to better understand the utility model, the embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. Fig. 1 has shown the composition structure of the present utility model, and this device realizes man-machine interaction through a " Tmr " screen (being interactive screen), and this device is made up of host computer, Rfid reader-writer, several coordinators (tuning antenna reaches impedance matching) , "Tmr" screen, and a medical-like rubber finger cot with a finger-sized card. The "Tmr" screen is composed of a radio frequency antenna layer d, a display screen c, and a touch screen b. It can be a sandwich structure. The layers are stacked together, from top to bottom are the touch screen, display screen and antenna layer, where the antenna layer is connected to the coordinator, the coordinator is connected to the reader, and the reader is connected to the host to control the reader Read and write the radio frequency card information in the fingertip. Users need to wear finger cots to interact with the device through the "Tmr" screen.

As shown in Figure 4, the special card holder we use is to add a card with information to our commonly used card holder, that is, to integrate the card into our fingertip, so that the card is easy to identify and easy to wear . Put a label on your finger, as shown in Figure 4, we use a label whose content can be rewritten. The data storage format identification code in this card can be changed, and the length is only one byte. Use It is convenient, we change the data storage format identification code (DSFID) in the card, and set the identification code of the card on each finger to a number that can be distinguished from each other. By sequentially setting the DSFID of the cards bound to the thumb, index finger, middle finger, ring finger, and little finger, the host can distinguish the clicks of different fingers on the interface.

Figure 2 is the working flow chart of the device, and the device is working according to the flow chart: firstly, the user puts on the fingertip to operate the "Tmr" screen (that is, the interactive screen), and the touch screen detects the contact and reports to the computer The location information of the contact, and then the host controls the Rfid reader to turn on the antenna at the corresponding position to detect the card information on the top of the screen. If the Rfid card is not detected, the device will treat the contact as a normal contact by default. If the card is detected, the position information of the contact is bound to the data information in the card, so a new type of contact with card information is generated, and then the host passes this new type of contact to the application program for corresponding processing.

Here is a specific application example, as shown in Figure 5, a new type of electronic organ, which is a handheld electronic device based on radio frequency identification, including a touch screen based on radio frequency identification, a speaker playback module, and finger cots or five-finger gloves; The identified touch display screen includes from the outside to the inside: a touch screen layer, a display screen layer and a radio frequency identification antenna layer. When the five-finger glove is in contact with the touch display screen, the touch display screen identifies the contacted finger glove or the radio frequency identification card of the five-finger glove through the radio frequency identification antenna layer. By comparing the identified radio frequency identification card with the target radio frequency identification card, it is judged whether the finger in contact with the specific "key" is the target finger, so as to judge whether the player's fingering is correct or not, which is convenient for the self-study and independent practice of the electronic piano player .
