Abstract

A system and method are described for locking a touch sensitive screen input component of a device. The system and method receives input from an input component, adds the received input to a input sequence, and checks the input sequence against a key sequence. If the input sequence matches the key sequence, the system and method toggle the locked state of device input components.

Claims

1. A system for locking device input, the system comprising:

a plurality of device input components comprising;

a touch screen input component; and

a key input component comprising a plurality of input keys; and

an input locking sub system for selectively locking at least the touch sensitive screen input component when a first input sequence is received from the plurality of keys that matches a specific key sequence, and for selectively unlocking locked input components, including the touch sensitive screen input, when a second input sequence is received from the plurality of keys that matches the specific key sequence.

2. The system as claimed in claim 1, wherein the plurality of device input components further comprise at least one additional input device.

3. The system as claimed in claim 2, wherein one of the at least one additional input devices is a trigger activated input device selected from the group comprising:

a barcode reader;

an image capture device; and

an RFID tag reader.

4. The system as claimed in claim 2, wherein the additional input device is not locked by the input locking sub system.

5. The system as claimed in claim 1, wherein the input locking sub system is part of an operating system (OS) of the device, the OS having an input sub system, the input locking sub system passes received inputs from unlocked input components.

6. The system as claimed in claim 1, the system further comprising:

a plurality of input locking sub system settings, the settings for controlling the behaviour of the input locking sub system; and

a input locking sub system settings applications for allowing the input locking sub system settings to be modified.

7. The system as claimed in claim 6, wherein the key sequence is specified as one of the plurality of input locking sub system settings.

8. The system as claimed in claim 1, wherein the specific key sequence is a sequence of between 2 and 3 keys received from the key input component.

9. A method for locking input of a device, the device input comprising a touch sensitive screen input component and a key input component, the method comprising:

receiving an input from the key input component;

adding the received input to an input sequence;

checking the input sequence against a specific key sequence; and

toggling the locked state of at least the touch sensitive screen input component when the input sequence matches the specific key sequence.

10. The method as claimed in claim 9, further comprising:

toggling the locked state of the key input component.

11. The method as claimed in claim 10, further comprising:

passing the received input to an operating system(OS) of the device if the input component of the received input is not locked.

12. The method as claimed in claim 11, further comprising:

toggling the locked state of individual input components based on input locking sub system settings;

13. The method as claimed in claim 12, further comprising:

modifying the locking sub system settings with a locking sub system settings application.

14. A computer-readable medium storing instructions or statements for use in the execution in a computer of a method of locking input of a device, the device input comprising a touch sensitive screen input component and a key input component, the method comprising:

receiving an input from the key input component;

adding the received input to an input sequence;

checking the input sequence against a specific key sequence; and

toggling the locked state of at least the touch sensitive screen input component when the input sequence matches the specific key sequence.

15. The computer-readable medium as claimed in claim 14, wherein the method further comprises:

toggling the locked state of the key input component.

16. The computer-readable medium as claimed in claim 15, wherein the method further comprises:

passing the received input to an operating system (OS) of the device if the input component of the received input is not locked.

17. The computer-readable medium as claimed in claim 16, wherein the method further comprises:

toggling the locked state of individual input components based on input locking sub system settings;

18. The computer-readable medium as claimed in claim 17, wherein the method further comprises:

modifying the locking sub system settings with a locking sub system settings application.

19. A propagated signal carrier carrying signals containing computer-executable instructions that can be read and executed by a computer, the computer-executable instructions being used to execute a method of locking input of a device, the device input comprising a touch sensitive screen input component and a key input component, the method comprising:

receiving an input from the key input component;

adding the received input to an input sequence;

checking the input sequence against a specific key sequence; and

toggling the locked state of at least the touch sensitive screen input component when the input sequence matches the specific key sequence.

20. The propagated signal carrier carrying signals as claimed in claim 19, wherein the method further comprises:

toggling the locked state of the key input component.

21. The propagated signal carrier carrying signals as claimed in claim 20, wherein the method further comprises:

passing the received input to an operating system (OS) of the device if the input component of the received input is not locked.

22. The propagated signal carrier carrying signals as claimed in claim 21, wherein the method further comprises:

toggling the locked state of individual input components based on input locking sub system settings;

23. The propagated signal carrier carrying signals as claimed in claim 22, wherein the method further comprises:

modifying the locking sub system settings with a locking sub system settings application.
