1 a) depicts a system 100 according to an embodiment. The system 100 includes a keyboard 197 (second device) and a key value generation unit 196.

The keyboard includes a plurality of key elements 101. In an embodiment, each key element 101 includes a reflector 102 that can reflect at least some of the light incident on the reflector 102. In alternative embodiments, a portion of the key element 101 (eg 50% of the key element 101) includes a reflector 102.

In embodiments where at least a portion of the key element 101 includes each reflecting portion, the reflecting portion 102 may include a diffuse reflecting layer. Above and below, the diffuse reflecting layer can be a reflecting layer for reflecting and / or scattering electromagnetic radiation in all directions (ie, in virtually all possible directions). Diffuse reflection may be that light is reflected from the surface such that the incident light is reflected at multiple angles rather than just one angle as in the case of specular reflection (ie specular reflection). In an embodiment, the reflected electromagnetic radiation is visible to the naked eye, ie, the wavelength range may range from approximately 380 nm (ultraviolet light) to approximately 750 nm (red light).

Reflector 102 may be disposed on top of key element 101 as indicated in FIG. The reflector 102 may be fixedly connected to the key element 101 by adhesive, vulcanization, or the like.

The keyboard 197 (second device) may include a mat 105 that may be made of and / or include an elastic and soluble material such as rubber. The rubber mat 105 may include a plurality of protruding elements, such as dome elements 106, 107, 109, which may provide tactile feedback. The domed elements 106, 107, 109 can be made of the same material as the mat 105. The mat 105 comprising the domed elements 106, 107, 109 may be cast in one embodiment in one piece. The domed elements 106, 107, 109 may be open at both ends 117, 118 and may be hollow, for example, to allow the passage of light.

Each key element 101 may be fixedly coupled to at least one domed element 106. As can be seen in FIG. 1 a), the key element 101 is fixedly coupled to one domed element 107 and the key element 108 is fixedly coupled to the two domed elements 106 and 109. The number of domed elements 106, 107, 109 fixedly coupled to the key elements 101, 108 is such that a large key (such as a space key) can be connected to a plurality of domed elements and a small key (such as a sign key) is one It can vary depending on the size of the key element so that it can be connected to the domed element.

In a computer keyboard, for example, the shift key may be fixedly coupled to two domed elements, the letter and number keys may be fixedly coupled to one domed element, and the spacebar may be fixedly coupled to four domed elements.

The term “fixedly coupled” should be understood to mean that the key element may be seated on the domed element and / or may be glued or vulcanized to the domed element and / or welded to the domed element.

In an embodiment, the domed elements 106, 107, 109 allow to control the range within which the key elements 101, 108 can move. In an embodiment the domed elements 106, 107, 109 can limit the direction in which the key elements 101, 108 can move. In an embodiment, the direction in which the key element can move can be in a direction 110 perpendicular to the rubber mat 105 or substantially perpendicular to the rubber mat 105, such as 90 degrees +/- 5 degrees.

To deform the domed element, an external force by the user 103 pressing the associated key element is required. The domed element is made of soft plastic, rubber, or any other material that can be deformed substantially along the direction of movement 110 when an external force having a component of the direction of movement 110 is applied to the key element 101. Or may include the material.

In an embodiment, the domed element 106 may be configured to require a critical force in the direction of movement 110 prior to deformation of the domed element. This provides a tactile response to a user applying a force to the key element 101 such that the dome element weighs the weight of the key element 101 without any substantial deformation in the direction of movement of the key element 110 when no external force is applied. It can be supported. This allows the domed elements 106, 107, 109 to provide tactile feedback in response to a user's action, such as a user's pressing of a key element.

The key element 101 may be made of a material harder than the domed element and / or include a material harder than the domed element. For example, the key element 101 may be made of melamine resin or include melamine resin.

In addition, the keyboard 197 (second device) may be communicatively coupled to the key value generation unit 196 via a communication link 193. In an embodiment, communication link 193 is established through a short range wireless transceiver contained within keyboard and key value generation unit 196. The communication link 193 may be established between the Bluetooth transceiver 195 in the keyboard 197 and the similar transceiver 194 in the key value generation unit 196. In an embodiment, the communication coupling provides a connection between keyboard 197 and key value generation unit 196 and includes a data-cable such as a USB cable or the like.

1 b shows a circular cross sectional view along the X-X axis of the domed elements 106, 107, 109.

1C shows a square cross sectional view along the X-X axis of the domed element 106, 107, 109.

The domed elements 106, 107, 109 are at both ends, i.e., the end 117 facing the key elements 101, 108 and the end 118 facing (or located on the mat) the rubber mat 105. Can be opened.

In an embodiment, the keyboard 197 may further include a printed circuit board (PCB) 115 that includes a plurality of pads 119 for determining whether the key elements 101, 108 have been pressed.

Each pad 119 includes first and second pad portions, the first pad portion being electrically insulated from the second pad portion. When the key element 101 is pressed, the conductive element 120 (fixedly connected to the mat 105 in close proximity to the key element 101) comes into contact with the first and second pad portions, whereby at least one The first and second pad portions of the pad 119 are shorted. This makes it possible to detect the pressed key element 101.

As shown in FIG. 1A, an elastic and stretchable mat 105 may be disposed between the PCB 115 and the plurality of key elements 101, 108. The PCB 115 can thus be arranged under the flexible mat 105 during normal operation of the keyboard, ie in situations where the keyboard is positioned on a horizontal plane with the key elements facing up for operation by the user.

The PCB circuit may be communicatively coupled to the short range wireless transmitter / receiver 195 via a wireless and / or wired communication link such as Bluetooth or cable. The detected value of the pressed key element 101 can be transmitted from the PCB circuit to the processing unit 1001 for further processing.

The key value generation unit 196 includes a short range wireless transmitter / receiver 194 as disclosed above.

The key value generation unit 196 may also include a light projecting unit 192. The light emitter 192 (ie, the first light emitter) is adapted to project key values (eg, alpha-numeric values) on at least one of the key elements 101 of the keyboard 197. The light projector 192 may provide the key values of all the key elements 101 of the keyboard 197, for example, by projecting the key values on the key elements.

In an embodiment, the key value generation unit 196 may comprise a mobile communication device, such as a cellular phone, wherein the emitter included in the mobile communication device comprises a dynamic RGB color image projector.

In an embodiment, the key value generation unit 196 may include a processing unit 1001. The processing unit 1001 may be communicatively coupled to the short range wireless transmitter / receiver 194 via wires. Thus, the processing unit 1001 can receive data regarding whether the key element has been pressed.

Additionally or instead, processing unit 1001 may be communicatively coupled to light emitter 192 via a wire, thereby determining which sign should be indicated on which key element 101 by light emitter 192. . The processing unit 1001 may provide a plurality of control signals to the light emitter 192 to control the key value transmitted to each key element 101.

The key value generation unit 196 thereby controls the alphanumeric values displayed on each key element 101, and the processing unit 1001 determines which alphanumeric values are associated with which key element 101. FIG. Can continue to be detected. This allows the processing unit 1001 to continue to detect the alphanumeric value displayed by the key element 101 in addition to the key element being pressed.

The distance between the mutually opposing inner surfaces of the fixture 205 may correspond to the size of the reflector 102 in each dimension of the plane bearing the reflector 102. Fixture 205 may be made of, or include, a hard plastic or rubber material, for example, to provide a securing platform on which key element 101 may be placed.

In an embodiment, the fixture 205 may conduct current. For example, hard plastics or rubbers may be doped with metal powders such as iron or the like. Additionally or instead, the fixture 205 may contain wires that provide an electrically closed loop.

The keyboard includes a detection unit 111, which may be a PCB as disclosed above. In addition or instead, the detection unit 111 is deposited on the detection unit 111 comprising a field corresponding to the stator 205 of each key element 101, and is made of plastic or rubber. It may be a capacitive detection unit comprising an opening 299 defined by the same electrical insulating layer 206. Thereby, when the key element 101 is pressed, the capacitance detecting unit 111 can detect the press by a change in the electric field corresponding to the opening 299 of each pressed key element 101.

As such, the keyboard of FIG. 4 can be used in conjunction with capacitive detection of whether a key element has been pressed. This may be an alternative to PCB detection or an additional key element press detection method.

FIG. 6A illustrates a system 600 that includes a mobile communication device 601, such as a cellular phone, that includes a light emitter 602. System 600 includes a device 197 (second device) that includes a plurality of diffuse reflectors 101.

Device 197 (second device) includes a processor and may include a docking bay 603 for a mobile communication device 601, such as a cellular phone, a portable digital terminal, or the like. Docking bay 603 may be in the plane of device 197 and / or may be included within device 197.

In an embodiment, the device 197 comprises a keyboard as described in connection with a) of FIG. 1 to include a diffuse reflective layer of the key element 101. The keyboard 197 includes a docking bay 603 in which the mobile communication device 601 may be disposed. Docking bay 603 may include a socket such as USB or a small USB socket to enable communication coupling with mobile communication device 601 disposed in corresponding docking bay 603.

In an embodiment, the device 197 includes a flat surface that can reflect incident light. The flat surface may be a plastic or metal plate comprising a diffuse reflective surface. The detection unit may be included in the flat surface to detect which portion of the flat surface the user is touching.

In an embodiment, the detection unit comprises an IR light source that provides an IR plane above and parallel to the flat plane (eg, during use of the keyboard). The IR plane may be 1 mm above the flat plane. When the user touches a portion of the flat surface, the IR light is reflected from the IR plane, and a portion of the reflected IR light is collected by the CMOS or CCD detector. Based on the detected light, the position of the portion of the flat surface touched by the hand can be determined by the processing unit.

In an embodiment, the detection unit comprises two metallic and electrically conductive layers separated by narrow gaps and disposed on the flat surface. When an object, such as a finger, pushes down a point on a flat surface, two metallic layers are connected to each other at that point, and the conductive layer then acts as a pair of voltage dividers to which the outputs are connected. This results in a change in the current registered as a contact event and sent to the controller for processing.

In an embodiment, the detection unit comprises a surface acoustic wave generator SAW disposed in connection with the flat surface such that the ultrasonic waves pass on the flat surface. When an object, such as a hand, touches the flat surface, part of the SAW is absorbed. The change of the ultrasonic wave enables the position registration of the touch event and the information may be transmitted to the processing controller.

In an embodiment, the detection unit comprises an insulator, such as glass, coated with a transparent conductor such as indium tin oxide (ITO) and disposed on a flat surface. Since the human body is a conductor, the finger touching the flat surface causes distortion of the electrostatic field of the finger, which is measurable as a change in capacitance. Other techniques can be used to determine the location of the touch. The location can be transferred to a processing unit adapted to calculate the point at which the user's touch is located on the flat surface.

When placed in the docking bay 603 as shown in FIG. 6B, the mobile communication device 601 can be communicatively coupled to the device 197 via a socket. This allows the mobile communication device 601 to be communicatively coupled to the PCB of the keyboard via the data bus and / or to the IR detector of the flat surface via the data bus. Therefore, it may be determined by the mobile communication device 601 which key element 101 of the keyboard is pressed or which part of the flat surface is touched.

The light projector 602 of the mobile communication device 601 may also illuminate the reflective layer 102 and thus specify the value of the key element 101 of the keyboard 197 or the value of one or more portions of the flat surface. The floodlight 602 may thus be a value of the key element 101 of the keyboard 197, for example a letter-numerical value, or a value of a portion of the flat surface, for example a letter-numeric value or a value of a gaming piece or a gaming board. Etc. can be provided.

The mobile communication device 601 may further detect which key element or which portion of the flat surface is provided with a value. This can be accomplished via a docking bay 603 that can be communicatively coupled to the PCB 115 of the keyboard or to the IR detector of the flat surface. When connected to the docking bay 603, the mobile communication means 601 may be communicatively coupled to the PCB 115 or to the IR detector through the docking bay 603. The mobile communication means 601 also controls the light emitter included in the mobile communication means 601. In an embodiment, the mobile means 601 may be communicatively coupled directly to the PCB 115 or the IR detector via a data bus. Communication coupling can be established using Bluetooth or a data cable or the like.

Thus, the mobile communication device 601 controls the light emitter 602 and detects the touched value of the key element 101 or part of the flat surface (i.e., at least at least, through communication coupling with the PCB 115 or IR detector). By processing the detection of the corresponding value), the processing unit 1001 of FIG. Thus, the mobile communication device can control which value is associated with which key element 101 or which portion of the flat surface. The mobile communication device 601 also detects which key element 101 / part of the flat surface the user 103 presses, and thus detects a value corresponding to the key element 101 / part of the flat surface when pressed. This can be done via a communication link with the PCB 115 or IR detector via the data bus.

This allows the mobile means 601 to provide the processing power of the system 600 together with the value of the key element 101 of the keyboard 197 or the value of the portion of the flat surface.

In an embodiment, the keyboard 197 or flat surface may comprise a power source such as a battery pack. This allows the mobile communication device 601 to be recharged upon placement in the docking bay 603 when the light emitter 602 can provide the value of the key element 101 or portion of the flat surface.

In an embodiment, the first mobile communication device 601 disposed in the docking bay of the first flat surface device 197 is connected to the second flat surface device 197 via a communication link such as Bluetooth, LAN, WAN, or cable. And is communicatively coupled to a second mobile communication device 601 disposed in the docking bay. In this embodiment, the pico projector of each communication device comprises a common gaming surface (such as a chessboard), a first gaming piece set associated with the first mobile communication device and a second gaming piece set associated with the second mobile communication device. It can be adapted to project. Thus, the user of the first mobile communication device and the user of the second mobile communication device can play a game against each other without necessarily being in close proximity to each other. The first and second mobile communication devices can exchange information about the position or other parameter of the gaming piece via the communication link.
