Abstract

The present disclosure provides for an ambiguous keyboard comprising at least two switches for performing keyboard actions, at least one of the two switches being a swipe-switch. The swipe switch can alter at least one characteristic selected from a group including: a) a function of at least one switch of the at least two switches of the ambiguous keyboard; and b) a mode of a second swipe-switch of the ambiguous keyboard.

Claims

1. An apparatus comprising

i) a gesture recognizer capable of determining from a given actual gesture by a user which of a plurality of switches said user intended to activate and then activating said determined switch,

ii) a symbol-input switch for inputting symbols, said symbol-input switch activated by taps,

iii) a swipe-switch, said swipe-switch corresponding to an ideal form fixed in location, such that said gesture recognizer can determine whether said user intended to activate said swipe switch by quantitatively comparing said actual gesture to said corresponding ideal form in its said fixed location.

2. The apparatus of claim 1 comprising a symbol-input swipe-switch which inputs a symbol when activated.

3. The apparatus of claim 1 further comprising a regular array of symbol-input switches, said plurality of symbol-input switches comprising a plurality of modal switches, and further comprising a modal swipe-switch operating such that when said modal swipe-switch is activated just before or during activation of each said modal switch, said each modal switch changes mode, in that said each modal switch inputs a first said symbol when activated just after or during said activation of said modal swipe-switch and a second symbol when said swipe-switch is inactive or other said gestures have occurred and been recognized by said gesture recognizer since the last said activation of said modal swipe-switch.

4. The apparatus of claim 3 further comprising linear swipe-switches each activated when an associated linear swipe gesture is recognized by said gesture recognizer, and further comprising a hold area, said hold order beyond said regular array of symbol-input switches but adjoining it, in the direction of said linear swipes, said hold area operating to continue the activity of said linear swipe-switches when a said linear swipe is continued in a continuous motion into said hold area and held in said hold area, whereby said hold area performs a hold action for a said linear swipe-switch, said swipe recognizer together with said hold area forming a swipe-switch-hold control.

5. The apparatus of claim 1, comprising at least two swipe-switch each of which performs a first function when said gesture recognizer recognizes said at least two swipe-switches as being intended by said user to be activated individually, and said at least two swipe-switches collectively perform a second function when said gesture recognizer recognizes that said user intended to activate said at least two swipe-switches in conjunction.

6. The apparatus of claim 1 wherein said gestures recognizable by said gesture recognizer include at least one of:

a vertical linear swipe, a horizontal linear swipe;

an open arc;

a path curved on itself;

a zig-zag curve;

a pull apart swipe; and

a two-thumb swipe wherein thumbs move along parallel lines in opposite directions.

7. The apparatus of claim 6, wherein a said gesture recognizable by said gesture recognizer is a said horizontal linear swipe along a single row of said regular array of symbol-input switches.

8. The apparatus of claim 1, further comprising two distinct said swipe-switches, said two swipe-switches forming an array, in that each of said two distinct swipe switches is activated by a distinct said gesture, said distinct gestures of the same form but distinguished by their spatial location.

9. The apparatus of claim 3, further comprising at least one of:

a swipe-switch activated in response to a linear gesture between two rows of said switches in said regular array and switches, a swipe-switch activated in response to a linear said gesture between two columns of said regular array of switches.

10. The apparatus of claim 3, wherein said regular array of switches comprising a plurality of said switches which input letters, said letters assigned to said switches following the within-row left-to-right order and letter-to-row assignments of a standard typewriter layout for a given natural language.

11. The apparatus of claim 10, where said standard typewriter layout is the Qwerty layout and said given natural language is English.

12. The apparatus of claim 1, wherein said swipe-switch is a lockable and holdable meta-key.

13. The apparatus of claim 12 wherein said lockable and holdable meta-key is at least one selected from a group comprising:

a) an end of set (EOS) lock; and

b) an EOS hold.

14. A keyboard comprising:

i) keys for inputting symbols,

ii) an activation mechanism sensitive to actual swipes by a user;

iii) a keyboard coupled to said activation mechanism;

iv) a plurality of ideal paths for swipes fixed in location and shape, said plurality localized at least partly within said keyboard, where said activation mechanism compares each of said actual swipes by a user to each of said ideal paths fixed in location and shape and then activates a switch corresponding to that said ideal path fixed in location and shape which best matches said actual swipe, implementing a swipe-switch.

15. The keyboard of claim 14, where said plurality of ideal paths fixed in location and shape includes at least two distinct said ideal paths fixed in location and shape which are linear paths substantially parallel to each other, and physically separated from each other sufficiently that said user can linearly swipe across said keyboard such as to perform said actual swipe such that either one or the other of said two distinct substantially parallel fixed ideal paths are matched to said actual swipe by said activation mechanism.

16. The keyboard of claim 14 where a plurality of said ideal paths fixed in location and shape are visually represented to guide said user to perform said actual swipe so as to cause said activation mechanism to likely match an intended one of said ideal paths fixed in location and shape.

17. The keyboard of claim 14, where at least one of said keys for inputting symbols inputs a first symbol when tapped alone, and inputs a second symbol when said at least one swipe-switch is activated just before or during a tap on said at least one key for inputting symbols.

18. The keyboard of claim 14 further comprising a hold area, said hold order beyond said keyboard but adjoining it, such that any said ideal path fixed in location and shape which continues into said hold area is such that when it is matched to a said actual swipe which continues to be held in said hold area, then any action performed by said swipe-switch implemented by said ideal path is continued as long as said actual swipe is held in said hold area, said activation mechanism together with said hold area forming a swipe-switch-hold control.

19. The keyboard of claim 14 where at least one of said ideal paths fixed in location and shape is along one row or column of said keyboard.

20. A keyboard, comprising:

four quadrants each representing a key, with a first assignment of letters to each of said quadrants, said letters to be input when each of said quadrants is tapped, said first assignment of letters equal to a first assignment of letters to four keys of a standard telephone keypad, and wherein said four quadrants may also be tapped in pairs, each said pair inputting letters when tapped, and such that a second assignment of letters is made to each of said pairs, said second assignment of letters being equal to a second assignment of letters to a second set of keys of a standard telephone keypad, whereby a standard telephone keypad with letters assigned to up to 10 keys can be emulated with said four quadrants.
