Abstract
A method, device, and program product are provided for no-look entry of digits in a multi-touch device. A multi-touch screen of the multi-touch device senses an initializing combination of at least one touch. A no-look digit entry application assigns a binary value to each touched location. The multi-touch screen detects at least one combination of at least one touch of the touch screen. The no-look digit entry application determines the locations touched and enters digit inputs corresponding to the sum of the binary values assigned to the locations for each detected combination of touches.
Claims20
A method for no-look entry of digits in a multi-touch device, comprising:
- sensing an initializing combination of at least one touch on a touch screen;
- creating a target location at a location of each touch of the initializing combination, wherein each target location lacks a corresponding on-screen indicator;
- assigning a binary value to each target location;
- detecting at least one combination of at least one no-look touch of the touch screen;
- determining the target locations touched;
- and
- entering a predetermined digit input corresponding to the sum of binary values assigned to the target locations for each detected combination of no-look touches.
A multi-touch device configured for no-look entry of digits, comprising:
- a multi-touch screen;
- a processor operably connected with the multi-touch screen;
- and
- a memory operably connected with the processor and having encoded thereon a no-look digit entry application executable by the processor to:
- sense an initializing combination of touches on a touch screen at a plurality of locations to create one or more target locations that lack a corresponding on-screen indicator;
- assign a binary value to each touched location according to a predetermined pattern;
- detect combinations of no-look touches of the touch screen;
- determine the locations touched;
- and
- enter predetermined digit inputs corresponding to the binary values assigned to the locations for each detected combination of no-look touches.
A program product, comprising a non-transitory computer readable storage medium having encoded thereon a computer executable program of instructions, comprising:
- program instructions for sensing an initializing combination of at least one touch on a touch screen to create one or more target locations that lack a corresponding on-screen indicator;
- program instructions for assigning a binary value to each touched location;
- program instructions for detecting at least one combination of at least one no-look touch of the touch screen;
- program instructions for determining the locations touched;
- and
- program instructions for entering predetermined digit inputs corresponding to the sum of the binary values assigned to the locations for each detected combination of no-look touches.
