Detecting hovering keypresses based on user behavior
Systems and methods for dynamically predicting keypresses on a hovering keyboard based on user behavior are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: configure a travel distance for hovering events detectable by a keyboard coupled to the IHS, and modify the travel distance in response to a user's behavior.
1. An Information Handling System (IHS), comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to:
configure a travel distance for hovering events detectable by a keyboard coupled to the IHS, wherein the travel distance is the distance a user's finger moves between an initial position of the user's finger and a position above the keyboard that triggers the detectable event; and
modify the travel distance into a modified travel distance in response to a behavior of the user.
2. The IHS of claim 1 , wherein the travel distance is 2 mm.
3. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to identify the user's behavior using a machine learning algorithm.
4. The IHS of claim 3 , wherein the program instructions, upon execution, further cause the IHS to classify the user into one of a plurality of different classes, and to modify the travel distance according to the classification.
5. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to modify the travel distance, at least in part, in response to execution of a selected application.
6. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to:
detect a first hovering event in response to a user's finger moving by at least the travel distance; and
after a modification of the travel distance, detect a second hovering event in response to the user's finger moving by at least the modified travel distance.
7. The IHS of claim 6 , wherein the modified travel distance is smaller than the travel distance.
8. The IHS of claim 6 , wherein the modified travel distance is greater than the travel distance.
9. The IHS of claim 1 , wherein the user's behavior comprises a number of hovering events detected within a selected time interval.
10. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to illuminate a region of the keyboard corresponding to a detected hovering event.
11. The IHS of claim 10 , wherein the program instructions, upon execution, further cause the IHS to illuminate the region of the keyboard with a color corresponding to the modified travel distance.
12. A method, comprising:
setting a minimum height and a minimum travel distance for hovering events detectable by a hovering keyboard, wherein the travel distance is the distance between an initial position of a user's finger and the minimum height;
detecting a first hovering event in response to a user's finger crossing the minimum height and exceeding the minimum travel distance;
based on a behavior of the user, modifying the minimum travel distance to a modified travel distance; and
detecting a second hovering event in response to the user's finger movement exceeding the modified travel distance.
13. The method of claim 12 , wherein the user's behavior comprises a minimum number of hovering events detected within a selected time interval.
14. The method of claim 13 , wherein the modified minimum travel distance is shorter than the minimum travel distance.
15. The method of claim 13 , further comprising:
illuminating a region of the keyboard corresponding to a hovering event with a first color or intensity corresponding to the minimum height.
16. A hardware memory device having program instructions stored thereon that, upon execution by a processor of an Information Handling System (IHS), cause the IHS to:
configure a travel distance for hovering events detectable by a keyboard coupled to the IHS, wherein the travel distance is the distance of a user's finger movement between an initial position of the user's finger and a position above the keyboard that triggers the detectable event; and
modify the travel distance in response to the user's behavior.
17. The hardware memory device of claim 16 , wherein the user's behavior comprises a number of hovering events detected within a selected time interval.
18. The hardware memory device of claim 17 , wherein the modified travel distance is smaller than the travel distance in response to the number of hovering events being greater than a threshold.
19. The hardware memory device of claim 17 , wherein the modified travel distance is greater than the travel distance in response to the number of hovering events being smaller than a threshold.
20. The hardware memory device of claim 16 , wherein the program instructions, upon execution, further cause the IHS to illuminate a region of the keyboard corresponding to a detected hovering event with a parameter corresponding to the modified travel distance, and wherein the parameter is at least one of: color or intensity.
