## Abstract

Fully stand alone and portable capacitive touch screen finger touch simulator clips onto for attachment member for attaching to any capacitive touch screen device, a touch screen engaging conductive material which is provided with an electronically controlled electrical charge through programmed solid state electronics with rechargeable on board battery and no external moving parts—which simulates finger touch.

## Claims

### Claim 1

An electronic device comprising: an integrated flexible sprung clip; one or more conductive contact pads; and an electronic circuit; wherein the flexible sprung clip is configured to hold the one or more conductive contact pads permanently against a capacitance touch screen, and the electronic device is arranged such that the electrical charge dissipation rate of the one or more conductive contact pads is controlled by the electronic circuit, to autonomously simulate human finger contact at, and thus human usage of the capacitance touch screen.

### Claim 2 (depends on 1)

The electronic device of claim 1, further comprising a conductive clip insert, electrically connected to the one or more conductive contact pads.

### Claim 3 (depends on 1)

The electronic device of claim 1, further comprising a timing circuit which controls the timing of the modification of the electrical charge dissipation rate at the one or more conductive contact pads.

### Claim 4 (depends on 3)

The electronic device of claim 3, wherein the timing circuit is controlled by a microprocessor, in response to an external input signal from at least one of a user-operable switch and a sensor.

### Claim 5 (depends on 1)

The electronic device of claim 1, further comprising a rechargeable internal battery.

### Claim 6 (depends on 1)

The electronic device of claim 1, further comprising one or more tapered ramps to allow attachment to the capacitance touch screen.

### Claim 7 (depends on 1)

The electronic device of claim 1, further comprising a control switch for activating and deactivating the device.

### Claim 8 (depends on 1)

The electronic device of claim 1, wherein the one or more conductive contact pads has a profiled and textured contact surface.

### Claim 9 (depends on 8)

The electronic device of claim 8, wherein the one or more conductive contact pads has a moulded profiled surface, including concentric rings to simulate a human finger.

### Claim 10

A method of simulating human finger contact on a capacitance touch screen, the method comprising the steps of: a) providing an electronic device comprising: an integrated flexible sprung clip, one or more conductive contact pads, and an electronic circuit; b) configuring the electronic device to change the electrical charge dissipation rate of the one or more conductive contact pads according to a predetermined sequence when activated; c) attaching the electronic device to the capacitance touch screen via the flexible sprung clip; and d) activating the electronic device.

### Claim 11 (depends on 10)

The method of claim 10, wherein the predetermined sequence is pseudorandom.
