1. A computing system comprising:
- a touch screen;
one or more processing devices; and
one or more computer-readable storage media comprising computer-executable instructions that, when executed by the one or more processing devices, cause the one or more processing devices to;
provide a set of symbols for entry via the touch screen, the set of symbols including a first subset of symbols and a second subset of symbols, wherein the first subset of symbols is designated by contact of an index finger with the touch screen, the second subset of symbols is designated by contact of a middle finger and not the index finger with the touch screen, and the first subset of symbols does not share symbols with the second subset of symbols;
determine that multiple fingers come into contact with the touch screen simultaneously;
determine whether the multiple fingers that come into contact with the touch screen simultaneously include the index finger;
in a first instance when the multiple fingers that come into contact with the touch screen simultaneously include the index finger, select a first individual symbol from the first subset; and
in a second instance when the multiple fingers that come into contact with the touch screen simultaneously include the middle finger and do not include the index finger, select a second individual symbol from the second subset,wherein the second subset of symbols designated by contact of the middle finger lacks any symbol selectable by the middle finger and the index finger, andwherein the first subset of symbols includes different symbols selectable via;
the index finger alone;
the index finger and the middle finger without a ring finger and a little finger;
the index finger and the ring finger without the middle finger and the little finger;
the index finger and the little finger without the middle finger and the ring finger;
the index finger, the middle finger, and the ring finger without the little finger;
the index finger, the ring finger, and the little finger without the middle finger; and
the index finger, the middle finger, the ring finger, and the little finger.

Abstract
This document describes tools associated with symbol entry control functions. In some implementations, the tools identify a first finger that is in tactile contact with a touch screen. The first finger can select a subset of symbols from a plurality of symbols that can be entered via the touch screen. The tools can also identify whether one or more other fingers are in concurrent tactile contact with the first finger on the touch screen. The tools can select an individual symbol from the subset based on whether the one or more other fingers are in concurrent tactile contact with the first finger on the touch screen.

10. A method performed by a computing device, the method comprising:
-
identifying a finger that comes into contact with a touch screen of the computing device simultaneously with another finger, the finger being identified as either an index finger or a middle finger; when the finger is identified as the index finger, designating a first group of symbols that is associated with the index finger as a currently-designated group of symbols for entry, the first group including different first symbols selectable by; the index finger only; the index finger and the middle finger without a ring finger and a little finger; the index finger and the ring finger without the middle finger and the little finger; the index finger and the little finger without the middle finger and the ring finger; the index finger, the middle finger, and the ring finger without the little finger; the index finger, the ring finger, and the little finger without the middle finger; and the index finger, the middle finger, the ring finger, and the little finger; when the finger is identified as the middle finger, designating a second group of symbols that is associated with the middle finger as the currently-designated group of symbols for entry, the second group of symbols associated with the middle finger being different than the first group of symbols associated with the index finger, the second group including different second symbols selectable by the middle finger and the middle finger and the ring finger, the second group lacking a symbol selectable by the middle finger and the index finger; and based at least on another identity of the another finger that comes into contact with the touch screen simultaneously with the finger, selecting an individual symbol from the currently-designated group of symbols for entry to the computing device and displaying the individual symbol on the computing device. - View Dependent Claims (11, 12, 13)

14. A computing system comprising:
-
a touch screen; one or more processing devices; and one or more computer-readable storage media comprising computer-executable instructions that, when executed by the one or more processing devices, cause the one or more processing devices to; provide an index-finger selectable group of symbols including at least a first symbol selectable via an index finger alone, a second symbol selectable via the index finger and a middle finger without a ring finger and a little finger, and other symbols selectable via; the index finger and the ring finger without the middle finger and the little finger; the index finger and the little finger without the middle finger and the ring finger; the index finger, the middle finger, and the ring finger without the little finger; the index finger, the ring finger, and the little finger without the middle finger; and the index finger, the middle finger, the ring finger, and the little finger; provide a middle-finger selectable group of symbols including at least a third symbol selectable via the middle finger and a fourth symbol selectable via the middle finger and the ring finger, the middle-finger selectable group of symbols lacking any symbol selectable via the middle finger and the index finger; determine identities of different fingers contacting the touch screen simultaneously; when the identities of the different fingers contacting the touch screen simultaneously include the index finger, select different symbols from the index-finger selectable group for entry to the computing system; and when the identities of the different fingers contacting the touch screen simultaneously include the middle finger and not the index finger, select different other symbols from the middle-finger selectable group for entry to the computing system. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
