Description

User input device
Description
The present invention relates to a user input device.
User input devices in the form of capacitive sensing devices (colloquially referred to as "touchpads") are known. Such devices are usually incorporated into displays of portable or handheld computing devices, such as portable digital assistants (PDAs), mobile communication device and game consoles. Thus, such devices tend to be somewhat complex.
EP 2 026 180 A describes a transparent, capacitive sensing system for providing input to electronic devices. The sensing system can be used to emulate physical buttons or slider switches that are either displayed on an active display device or printed on an underlying surface. The capacitive sensor can be used as an input device for a graphical user interface, especially if overlaid on top of an active display device like an LCD screen to sense finger position and contact area over the display.
Because the sensor is substantially transparent, the underlying surface can be viewed through the sensor.
Although the capacitive sensing system described in EP 2 026 180 A can be used as an input device, the capacitive sensor must be transparent. To achieve this, the conductive traces and conductive shields must be transparent which requires use of transparent conductive material, thin layers of conductive material and/or narrow traces. Thus, such a capacitive sensing system is more complex and/or more expensive to manufacture.
The present invention seeks to provide a user input device which is easier and/or cheaper to manufacture.
According to a first aspect of the present invention there is provided a user input device comprising at least one sheet including a sheet having a first face and a second, opposite face, capacitive sensing elements formed on the first face of the Case: 60293GB 1 sheet, an interface to the capacitive sensing elements for providing signals to a computing device and indicia printed on the second face of the sheet or on a visible face of an overlay sheet covering a face of the sheet, wherein the sheet, the overlay sheet and/or another sheet interposed between the sheet and the overlay sheet is (are) opaque.
Thus, transparent sheet need not be used and capacitive sensing elements need not be transparent. This can make the device cheaper and easier to make. Furthermore, the overlay can provide a protective barrier. Moreover, the appearance and feel of the overlay can be enhanced.
The capacitive sensing elements may comprise a plurality of conductive pads formed on the sheet and a plurality of conductive tracks formed on the sheet, each track having connected to a respective pad, wherein the interface includes a capacitive sensing module having as a first set of terminals connected to the tracks.
The plurality of conductive pads may comprise conductive ink. The plurality of conductive tracks may comprise conductive ink.
The interface may include a bus module. The bus module may be a universal serial bus module.
At least part of the interface, e.g. the capacitive sensing module, may be bonded to the sheet.
The overlay sheet may be attached to the sheet. The overlay sheet and the sheet may be laminated together.
The user input device may be a poster.
The sheet or at least portions of the sheet may be opaque. The overlay sheet or at least portions of the overlay sheet may be opaque.
The capacitive sensing sheet and the overlay sheet may be unitary, i.e. a single sheet can be used instead of separate overlay sheet and capacitive sensing sheet. For example, indicia can be printed on one side of a sheet and the capacitive sensing elements, e.g. tracks and optional pads, can be printed on the reverse side.
The sheet or overlay sheet may be coated with a layer which is opaque so as to make the sheet or overlay sheet opaque.
According to second aspect of the present invention there is provided a system comprising the user input device, the computing device connected to the user interface device and an output device configured to receive signals from the computing device. The output device may comprise a display.
According to a third aspect of the present invention there is provided method of fabricating a user input device comprising providing at least one sheet including a sheet having a first face and a second, opposite face, forming capacitive sensing elements on the first side of the sheet, printing indicia on the second face of the sheet or on a visible face of overlay sheet covering a face of the sheet, providing an interface to the capacitive sensing sheet for providing signals to a computing device and wherein the sheet, the overlay sheet and/or another sheet interposed between the sheet and the overlay sheet is (are) opaque.
The method may comprise attaching the overlay sheet to the capacitive sensing sheet.
Certain embodiments of the present invention win now be described, by way of example, with reference to the accompanying drawings in which: Figure 1 is a schematic view of a computer system including a user input device; Figure 2 is a schematic plan view of a capacitive sensing sheet and interface; and Figure 3 is a schematic plan view of the capacitive sensing sheet shown in Figure 2 and an overlay sheet.
Referring to Figure 1, a computer system I is shown comprising a user input device 2, a personal computer 3 and display 4. The user input device 2 is a peripheral device and is connected to the personal computer 3 by a bus 3. The personal computer 3 can be a laptop computer. In this and some other examples, the display 4 can take the form of a flat-panel display (e.g. plasma screen display or liquid crysta' dispthy. However, the dispthy 4 can be projector (e.g. liquid crysta' dispthy or digital light processing display). In this and some other examples, the bus 5 is a universal serial bus (USB).
The computer system 1 can be used as part of a display or stand, for example, at a trade show, exhibition or other type of event. The user input device 2 can be specially made for the event and can allow users, e.g. trade show delegates, customers, guests, etc, to interact with audio-visual content. For example, the user input device can be used to control a presentation on the display 4. The user interface 2 may take the form of a poster (e.g. mounted on a wall or other vertical or non-hori2ontal surface, or mounted or spread on a table top or other generally hori2ontal surface). The user interface 2 can be mounted behind a window or pane of glass, e.g. a shop window or information kiosk window. In some embodiments, the display 4 can be projector. Thus, the projector can project an image onto the user interface 2.
Referring also to Figures 2 and 3, the user input device 2 comprises a capacitive sensing sheet 6, an interface 7 to the capacitive sensing sheet 6 for providing signals to a computer 3 and an overlay sheet 8 supported by the capacitive sensing sheet 6 having indicia 9 printed thereon. The capacitive sensing sheet 6 and the overlay sheet 8 are laminated, for example bonded together using glue or tape. The sheets 6, 8 can be laminated between outer sheets 10.
The overlay sheet 8 can be opaque. The overlay sheet 8 is formed of an insulating (i.e. non-conductive) material. The overlay sheet 8 can be formed from paper, card, plastic or other flexible material. The indicia 9 may include text, icons, graphics and/or images. The indicia 9 can be printed. The indicia 9 can be opaque. The overlay sheet 8 can be embossed and/or the indicia 9 can take the form of raised print. For example, this can be used to improve the tactile feel of the user input device.
Referring in particular to Figure 2, the capacitive sensing sheet 6 comprises a sheet-like substrate 11 (simply referred to herein as a "sheet") having a face 12. The sheet 11 can be opaque. The sheet 11 is formed of an insubting (i.e. non-conductive) material. The sheet 11 can be formed from paper, card, plastic or other flexible material.
A plurality of conductive pads 13 and tracks 14 connected thereto are formed on the sheet It. In this and some other examples, the conductive pads 13 and tracks 14 comprise conductive ink and are printed using a printing process, e.g. inkjet printing, gravure etc., onto the sheet 11. The conductive ink can be, for example, carbon-based or metal based. However, the pads 13 and/or tracks 14 can comprise foil and may be formed by hot foil stamping. The conductive tracks 14 for sensing are typically less than 100 kQ.
The pads 13 provide capacitive sensing elements for sensing proximity of, for example, a user's finger. Although the user's finger need not come into contact with the device 1, let alone the pads 13, the device I can be referred to colloquially as a touch sensitive sheet or interactive sheet.
The pads 13 can have an area having an order of magnitude of 10 or 100 mm2, i.e. about the size of a finger print. The tracks 14 can have a width having an order of magnitude of 0.1 or 1 mm. In either case, the pads 13 and tracks 14 can be visible to the unaided eye.
A capacitive sensor may comprise a single pad, for example, if the system and the user (not shown) are well grounded. However, a capacitive sensor may comprise two pads, e.g. a sense pad and a ground pad. For example, the pads can take the form of interdigitated fingers, the form of a central pad and a ring or the form of a pad and a ground "area", e.g. in the form of pad or rail, which may be common to more than one sense pad. The grounding area is arranged so that the distance between the sense pad and the grounding area is larger than the distance between the user's finger and the sense pad, thereby helping to ensure that the path provided by user's finger is not dominated by the path to ground.
A single sheet may be used instead of the sensing sheet 6 and the overlay sheet 8.
For examp'e, indicia 9 may be printed on one face of a sheet and pads 13 and/or tracks 14 can be printed on the other side.
A capacitive sensor module 15 is used to detect user actuation. The module 15 comprises a capacitive touch microcontroller and suitable microcontrollers are available from Texas Instruments mc, Atmel Corporation, Microchip Technology Inc and other chip manufacturers. A set of terminals 16 provide electrical connections to the tracks 14. Conductive paste, tape or glue can be used to provide contacts or better/more reliable contacts between tracks 14 and terminals 16. The capacitive sensor module 15 can include a printed circuit board, a flex circuit or chip package. The microcontroller is mounted on the printed circuit board, a flex circuit or chip package.
The capacitive sensor module 15 is attached to a bus module 17 via flexible wires or other form of connection 18. The wires 18 may be formed in ribbon. The bus module 17 is separate so as to help reduce strain on the connector block 14, which might cause the sensor module 13 to become detached from the sheet 11.
The capacitive touch sensor module 13 and the bus module 17 can be integrated into a single unit or module. For example, the capacitive sensor module 15 may include a USB interface.
The sensor module 15 and/or the bus module 17 may be powered via the bus.
However, additionally or alternatively the sensor module 15 and/or the bus module 17 may have a local power source, e.g. a battery or solar cell. In some embodiments, the bus is provided via a wireless link instead of a wired link.
The sheet 11 may he cut so as to form a tab (not shown) projecting from the rest of the sheet 11, which may be rectangular. The bus module 17 and, optionally, the connector block 15, may be formed on the tab (not shown). Thus, the rest of the sheet 11 may be bonded or laminated to the overlay sheet 8 without the bus module 17.
Referring in particular to Figure 3, the overlay sheet 8 is attached to a reverse side of the sheet 11, for example, by glue or sandwiched between laminating sheets 10 (Figure 1). One of the sheets can be a window. The indicia 9 are printed on a face (or "side") 21 which face away from the capacitive sensing sheet 6, i.e. on top.
Thus, in use, the indicia 9 are not viewed through the capacitive sensing sheet 6.
Relevant indicia 9, 93, 94, 95 (e.g. those indicia which are intended to guide or show "active" regions which can be activated by the user) on the overlay sheet 8 can be aligned with the pads 13 on the sensing sheet 6. For example, the indicia may include "stop", "play", "pause", "fast-rewind" and "fast-forward" icons 9, 2, 93, 94, 9.
As shown in Figure 3, in some example, relevant indicia 9, 92, 93, 94, 9 need only be coarsely aligned with the pads 13.
The user input device 2 can be easily and cheaply manufactured. For example, the capacitive sensing sheet 6 can be printed without the need for special transparent inks or require especially narrow feature sizes. Capacitive sensing sheets 6, for example having several different arrangements of pads, can be made and the interface 7 attached and held in stock. The user input device 2 can be customised by simply printing the overlay sheet 8. Alternatively, the user input device 2 can be customised by printing on the reverse side of a capacitive sensing sheet 6. The interface 7 can he attached at this point. The capacitive sensing sheet 6, interface 7 and overlay sheet 8 can be easily assembled, e.g. laminated. In some cases, an end user can customise their own user input device.
lit \vill be appreciated that many modifications may be made to the embodiments hereinbefore described. For example, a sheet may be interposed between the capacitive sensing sheet and the overlay sheet. Other forms of bus can be used, e.g. other types of serial bus, e.g. RS-232, or a parallel bus.
The pads 13 can be omitted and the conductive tracks 14 may serve as capacitive sensing elements.
The capacitive sensing sheet can be configured to sense x-y position. Capacitive sensors can take the form of two sets of crossing conductive lines. For example, one set of conductive lines can be provided on one side of a sheet and another set of conductive lines can be provided on the reverse side of the sheet. Alternatively, the sets of conductive lines can be provided on the same side of the sheet, but separated by an insulating layer.
The capacitive sensors need not be buttons or switches, but can be sliders, rotors or other shapes.
The conductive tracks and/or pads may be printed on a sheet. A projector can project an image onto the sheet.
An overlay sheet can be added by the user to customise capacitive sensing sheet.
The capacitive sensing elements, e.g. pads and/or tracks, can be printed on the reverse of the graphics sheet and so only one sheet can be used. The capacitive touch sensors are read or sensed through the item being viewed.
In some examples, sheets may be coated so as to make them opaque.
