The following discussion is directed to the specific embodiments, which are intended to be illustrative only and not limiting of the scope of the invention. Figures 1 through 9 illustrate input systems and devices for capacitive touch using the principles of the present invention.

Particular embodiments of the present invention describe an input system for transferring digital data from one device to another using touch signal technology. According to an embodiment of the present invention, when the conductive material body corresponds to a predetermined capacitance value (for example, a human body), and the conductive material terminal of the input device is placed on a touch screen of a multimedia device, an input device Create a touch/release event on the touch screen of a multimedia device. As a result, a multimedia device can read and translate the touch/release event, perform an operation related to the touch/release event, causing, for example, displaying a picture or an image on the touch screen, or playing The sound of the multimedia device.

FIG. 1 shows an operational diagram for an input system of a multimedia device 100. An input system for the multimedia device 100 includes an input device 106 and a multimedia device 100 configured to transmit a touch/release event, and the multimedia device 100 is configured to receive from the input device 106. A touch/release event.

The input device 106 (Fig. 5) has the following components: an insulator 117 having one end attached to a conductive material body 107 and the other end attached to at least one conductive material terminal 109. The insulator 117 is provided to break or block the flow of electrical power from the conductive material body 107 to the conductive material terminal 109. The insulator 117 can be any non-conductive material such as rubber. Conversely, a stylus does not have an insulator 117 and is always in a connected state when a capacitive material 108 touches the stylus and the charge flows. The stylus cannot be controlled in the connected state or the disconnected state.

A switch unit 110 gives the input device 106 the ability to connect or disconnect between two states (connected or disconnected), wherein the switch unit 110 controls the connection or disconnection between the conductive material body 107 and the conductive material terminal 109. Connection means that the conductive material body 107 allows the flow of charge between the capacitive material 108 and the conductive material terminal 109, while disconnection means that there is no flow of charge. Once the capacitance of one of the capacitive materials 108 corresponds to a predetermined value (eg, a human body), touching the conductive material The body 107 and the switch unit 110 allow the input device 106 to be connected. To deliver a touch/release event to the multimedia device 100, the conductive material body 107 allows charge flow from a capacitive material 108 to the conductive material terminal 109.

The input device 106 also has a processing unit 111 for preparing and encoding preloaded information. The processing unit 111 has a storage unit embedded in the pre-loaded material of the processing unit 111 or the storage unit is separately present. In the case where the storage unit is separately present, pre-loaded data exists in the storage unit, and the processing unit 111 can access the storage unit by executing an instruction. The processing unit 111 prepares the pre-loaded material by encoding the pre-loaded data to a touch/release event. The processing unit 111 encodes the preloaded data by using a time difference, a phase difference, or a frequency difference of the touch/release event. The touch/release event is a sequence of touches and release of the touch screen 101 for a specific period of time. The touch/release event is predetermined by the pre-loaded data, wherein the touch and release actions are preset for a set amount of time and occur at a set frequency. For example, a 0.5 second touch and a 0.2 second release, then a 0.1 second touch, and the like.

In addition to preparing the preloaded data, the processing unit 111 controls the switch unit 110 such that the touch/release event is executed based on the preloaded data. The switch unit 110 is a power control switch made of an electronic circuit, a solid state relay or a mechanical relay that can be controlled by electric power. The processing unit 111 controls the switch unit 110 to perform the touch/release event on the touch screen 101 of the multimedia device 100, wherein the conductive material body 107 corresponds to a predetermined capacitance value and the conductive material terminal 109 contacts a multimedia device. The switch unit 110 can be executed when one of the devices 100 touches the screen 101. The switch unit 110 becomes a sequence of touch and release by connecting or disconnecting the touch/release event on the touch screen.

Another component of the input device 106 is a power source. The input device 106 requires electricity Force to operate. In order to obtain power, a power source can be embedded in the input device 106, wherein the power source stores power supplied to the input device 106. The power source can be in any form, such as charged or non-rechargeable. Alternatively, the input device 106 has a power connector that is coupled to an external power source.

The input system includes a multimedia device 100 configured to receive touch/release events from the input device 106. The multimedia device 100 has a capacitive touch sensor 105 that can measure the capacitance and position on the touch screen 101. The multimedia device 100 also has a processor 104 that can read raw material from the input device 106. Once the input device 106 touches the touch screen 101, the processor 104 of the multimedia device 100 measures the capacitance value from the capacitive touch sensor 105. If the capacitance value corresponds to a predetermined value, the processor 104 reads the original data received from the input device 106. After receiving the original, the processor 104 transmits the original data to an operating system 103 of the multimedia device 100. The operating system 103 converts the raw data into a touch/release event and transmits the touch/release event to an application 102. The application 102 is pre-loaded on the multimedia device 100, wherein the application 102 is configured to recognize and decode the touch/release event. After decoding, the application 102 performs the touch/release event to translate the touch/release event to occur, for example, in the display of the picture or image of the touch screen 101 or at the multimedia device 100. The touch screen 101 is configured to display occurrences and display the touch/release event.

In another embodiment, as shown in FIG. 2, the input device 106 includes a real time clock 112. The real time clock 112 can be embedded in the input device 106 to allow the input device 106 to identify the date and time. Thus the input device 106 can generate data that changes over time. The real time clock 112 allows the processing unit 111 to learn the current time and then decode to the touch/release event. The touch/release event can be allowed to be passed to the multimedia device 100 along with the time. The real time clock 112 also allows the input device 106 to transmit data based on time. for example, The preloaded data should only be transmitted to the multimedia device 100 at 10 am on Thursday. If the user touches the input device 106 on the touch screen 101 and is at 10 am on Thursday, the pre-loaded data will be transferred to the multimedia device 100. Another benefit of this real time clock is the change in data over time. As long as the time of the multimedia device 100 is synchronized with the time of the input device 106, different settings according to the data of the time can be transmitted. For example, the input device 106 should transmit the number 50 to the multimedia device 100 at noon on Tuesday, and the input device 106 should transmit the number 60 at 3 pm on the same day. When the user touches the input device 106 on the touch screen of the multimedia device 100 at noon on Tuesday, the number 50 is transmitted to the multimedia device 100. If the user touches the input device 106 on the touch screen of the multimedia device 100 at 3 pm on the same day, the number 60 is transmitted. At another time, based on the programs stored in input device 106 and multimedia device 100, the input device 106 can transmit some other number. The input device 106 is programmed to convert data according to time, and the multimedia device 100 has a program to receive different data according to time.

FIG. 3 shows a flow chart for an input system of the multimedia device 100. Once a capacitive material 108 touches the input device 106 and the conductive material terminal 109 of the input device 106 contacts the touch screen 101, the input system for the multimedia device 100 begins at step 200, wherein the processing unit 111 is ready to The pre-stored data of the input device 106 is transmitted to the multimedia device 100. The steps for preparing the data include data collection, encryption of the data, and data processing. Then in the step 201, the processing unit 111 encodes the preparation data to a touch/release event by an algorithm. The algorithm used to encode the touch/release event creates a physical layer of transmission. Then, in step 202, once the conductive material terminal 109 of the input device 106 contacts the touch screen 101, the touch/release event is transmitted to the multimedia device 100 through the touch screen 101. At step 203, the processor 104 The capacitance value from the capacitive touch sensor 105 is measured and the data is transmitted to the operating system 103. At step 204, the operating system 103 of the multimedia device 100 detects the data received from the processor 104 and determines which touch/release event has occurred. At step 205, if the touch/release event occurs, the operating system 103 will store and transmit the event to the application of step 206. In step 207, the application 102 identifies a sequence of the touch/release events. Then in step 208, the application 102 decodes the sequence of touch/release events. Step 209, after decoding, the application 102 performs operations related to the decoded signal. An example of successfully transferring data from the input device 106 to the multimedia device 100 is shown in FIG. The touch screen 101 displays a picture as a result of a successful data transfer.

FIG. 5 shows a specific embodiment of the input device 106. The input device 106 has an insulator 117, a conductive material body 107, and a conductive material terminal 109. In this particular embodiment, the input device 106 mimics a stamp that is typically used by manufacturers to imprint their loyalty cards. In order to transfer data from the input device 106 to the multimedia device 100, the input device 106 is imprinted on a digital point card located at the multimedia device 100.

In this particular configuration, the input device 106 has preloaded data for use in the application 102 preloaded on the multimedia device 100. The preloaded data at the input device 106 is a touch/release event that creates a special imprint. In order to transfer the special imprint from the input device 106 to the multimedia device 100, the multimedia device 100 must have a preloaded application 102 that can identify the touch/release event that created the special imprint. The application 102 preloaded in the multimedia device 100 is an application 102 for collecting imprints from participating vendors. The application 102 replaces the paper's point card, where the consumer typically receives a card from the manufacturer to accumulate the stamp. These user accumulative stamps can receive a discount or a free purchase. Having the application 102 reduces the need to store each card from each vendor. In addition to the imprint ready for the multimedia In addition to the device 100, each vendor has an input device 106 for pre-loaded special material from one of the various vendors. Thus, each input device 106 for each vendor has a different preloaded profile. The change in preloaded data is generated using the time difference, phase difference, or frequency difference of the sequence of touch/release events and/or contact locations. Therefore, a manufacturer can only provide users with a special stamp of their own store.

In order to fully utilize the input system for the multimedia device 100, the user must first download the application 102 to the multimedia device 100. Each time the user visits a manufacturer and purchases, the user opens the pre-loaded application 102, and the manufacturer embosses the input device 106 on the touch screen of the multimedia device 100. Therefore, a stamp for the manufacturer appears on the touch screen 101. The user collects the stamp in this way. An example of successful delivery of one of the imprints is shown in Figure 4.

Figure 6 shows another view of the input device 106. The input device 106 has a status indicator 114 on the body of electrically conductive material 107. The status indicator 114 is provided to inform the user of a particular status. The status indicator 114 can be configured to illuminate during actuation, such as when the material is in transit, when the material has been delivered, or when an error has occurred.

The input device 106 has a port 113 that is configured to receive material from an electronic device. The port 113 is used to connect the input device 106 to an electronic device such that the manufacturer or a manager can download the material transmitted to the multimedia device 100 on the input device 106. The input device 106 can also receive data via a wireless method. The port 113 is also configured to connect to a power source. When the port 113 is connected to a power source, the port 113 can be used to charge the input device 106.

Additionally, the input device 106 has a hole 115 in which the input device 106 can be placed on a drawstring. When the input device 106 is frequently used, the input device has a pull cord 106 is especially useful.

In another embodiment, as shown in FIG. 7, the input device 106 has the following components: an insulator 117 having one end attached to a conductive material body 107 and three conductive material terminals 116 attached to the other end. The input device 106 has the ability to transmit data using three conductive material terminals 116. This means that the data can be distributed to three conductive material terminals 116. Thus, the input device 106 has the ability to transmit more data in the same amount of time, and thus the data transfer is faster.

An input device 106 having three conductive material terminals 116 can be used to transfer data to a multimedia device 100 having a capacitive multi-touch sensor 105a. As shown in the operational diagram of FIG. 8, the input system for the multimedia device 100 has three input devices 106 of conductive material terminals 116. This operational diagram is similar to the input system for the input device 106 of the multimedia device 100 having a conductive material terminal 109. The input device 106 having three conductive material terminals 116 differs in that it has three switching units 110 that control one of the three conductive material terminals 116, respectively.

When the capacitive material 108 touches the conductive material body 107 and the conductive material body 107 corresponds to a predetermined capacitance value, the input device 106 having the three conductive material terminals 116 can transmit data, and the three input devices 106 are electrically conductive. The material terminal 116 is located on the touch screen 101 of the multimedia device 100 having one of the capacitive multi-touch sensors 105a. The processing unit 111 then prepares the preloaded data by decoding the preloaded data to a touch/release event. The processing unit 111 divides the touch/release event into three parts. The processing unit 111 controls each of the three switching units 110 to perform their portion on the touch screen 101 of the multimedia device 100 having one of the capacitive multi-touch sensors 105a. Each switch unit 110 becomes a sequence of touch/release by connecting or disconnecting, thereby performing the touch/release event on the touch screen 101. The multimedia device 100 having a capacitive multi-touch sensor can receive more than one touch/release event at a time. Once the input device 106 Touching the touch screen 101, the capacitive multi-touch sensor 105a of the multimedia device 100 measures the capacitance and position from the input device 106. If the capacitance corresponds to a predetermined value, the processor 104 reads each of the three original data from the input device 106. After receiving the original data, the processor 104 transmits the original data to an operating system 103 of the multimedia device 100. The operating system 103 converts the raw data into a touch/release event and transmits the touch/release event to an application 102. The application 102 preloaded on the multimedia device 100 recognizes and decodes the touch/release event. After decoding, the application 102 executes the touch/release event. The touch screen 101 is configured to display the result of the touch/release event. The input device 106 can have multiple conductive material terminals 109 and is not limited to one or three. The input device 106 having a plurality of conductive material terminals 109 is more suitable for transmitting more data to the multimedia device 100.

Figure 9 illustrates a flow diagram for an input system for the multimedia device 100, wherein the input device 106 in accordance with the present invention has more than one conductive material terminal 109. The input device 106 having a terminal of conductive material and the input device 106 having more than one terminal of conductive material differ only in the flow chart in that the processing unit 111 decodes the preparation data into the multiple sequence of the touch/release event. The touch/release event is transmitted in the same manner as an input system having an input device 106 of a conductive material terminal 109.

As noted above, the input system is an improved way of transferring data from an input device 106 to a multimedia device 100. Numerous applications 102 can be authored for use with the input device 106. The input device 106 can be used as a storage for any form of data transfer, and the application 102 is not limited to the examples described above.
