Circular Keyboard
At least one embodiment takes the form of a computing device comprising a processor and a data storage comprising instructions that, if executed by the processor, cause the computing device to present a transition region and one or more input regions. Each input region comprises a respective symbol. The computing device further detects a movement through the transition region (i) originating from a first input region and (ii) exceeding a threshold movement. The computing device then receives an indication comprising the first-input-region symbol.
1 . A method carried out by a computing device, the method comprising:
determining a plurality of digrams, wherein a given digram comprises two successive symbols in a plurality of symbols corresponding to a particular language;
for each of one or more of the plurality of digrams, determining a respective frequency at which the given digram occurs in the particular language;
determining an arrangement of the plurality of symbols within a plurality of input regions, wherein each of the symbols from the plurality of digrams is assigned to one of the input regions, and wherein the arrangement is such that a distance between the input regions corresponding to the symbols from a given digram positively correlates with the frequency at which the given digram occurs;
presenting a transition region and the plurality of input regions;
detecting a movement through the transition region (i) originating from a first input region and (ii) exceeding a threshold movement;
receiving an indication comprising the first-input-region symbol; and
presenting a confirmation associated with the indication.
2 . The method of claim 1 , wherein the plurality of input regions comprises respective letter regions, and wherein the respective symbol of each of the letter regions comprises a letter.
3 . The method of claim 1 , wherein the movement is a gaze-target movement.
4 . The method of claim 1 , wherein the transition region is circular.
5 . The method of claim 1 , wherein at least one of the plurality of input regions adjoins the transition region.
6 . The method of claim 5 , wherein every input region adjoins the transition region.
7 . The method of claim 1 , wherein the symbol comprises a letter.
8 . The method of claim 1 , wherein the threshold movement is a distance.
9 . The method of claim 1 , wherein the threshold movement is a displacement.
10 . The method of claim 1 , wherein the threshold movement is a velocity.
11 . The method of claim 1 , wherein the threshold movement is a movement within a selection region.
12 . The method of claim 1 , wherein presenting the confirmation associated with the indication comprises presenting the confirmation associated with the indication within the transition region.
13 . The method of claim 1 , further comprising executing a command associated with the indication.
14 . A computing device comprising:
a processor;
data storage; and
instructions stored on the data storage that are executable by the processor to cause the computing device to:
determine a plurality of digrams, wherein a given digram comprises two successive symbols in a plurality of symbols corresponding to a particular language;
for each of one or more of the plurality of digrams, determine a respective frequency at which the given digram occurs in the particular language;
determine an arrangement of the plurality of symbols within a plurality of input regions, wherein each of the symbols from the plurality of digrams is assigned to one of the input regions, and wherein the arrangement is such that a distance between the input regions corresponding to the symbols from a given digram positively correlates with the frequency at which the given digram occurs;
present a transition region and the plurality of input regions;
detect a movement through the transition region (i) originating from a first input region and (ii) exceeding a threshold movement;
receive an indication comprising the first-input-region symbol; and
present a confirmation associated with the indication.
15 . The computing device of claim 14 , wherein the plurality of input regions comprises respective letter regions, and wherein the respective symbol of each of the letter regions comprises a letter.
16 . The computing device of claim 14 , wherein the movement is a gaze-target movement.
17 . The computing device of claim 14 , wherein the transition region is circular.
18 . The computing device of claim 14 , wherein at least one of the plurality of input regions adjoins the transition region.
19 . The computing device of claim 18 , wherein every input region adjoins the transition region.
20 . The computing device of claim 14 , wherein the symbol comprises a letter.
21 . A non-transitory computer-readable medium having instructions stored thereon that are executable by a computing device to cause the computing device to:
determine a plurality of digrams, wherein a given digram comprises two successive symbols in a plurality of symbols corresponding to a particular language;
for each of one or more of the plurality of digrams, determine a respective frequency at which the given digram occurs in the particular language;
determine an arrangement of the plurality of symbols within a plurality of input regions, wherein each of the symbols from the plurality of digrams is assigned to one of the input regions, and wherein the arrangement is such that a distance between the input regions corresponding to the symbols from a given digram positively correlates with the frequency at which the given digram occurs;
present a transition region and the plurality of input regions;
detect a movement through the transition region (i) originating from a first input region and (ii) exceeding a threshold movement;
receive an indication comprising the first-input-region symbol; and
present a confirmation associated with the indication.
22 . The computer-readable medium of claim 21 , wherein the plurality of input regions comprises respective letter regions, and wherein the respective symbol of each of the letter regions comprises a letter.
23 . The computer-readable medium of claim 21 , wherein the movement is a gaze-target movement.
24 . The computer-readable medium of claim 21 , wherein the transition region is circular.
25 . The computer-readable medium of claim 21 , wherein at least one of the plurality of input regions adjoins the transition region.
26 . The computer-readable medium of claim 21 , wherein every input region adjoins the transition region.
27 . The computer-readable medium of claim 21 , wherein the symbol comprises a letter.
