Abstract

An aspect provides a method, including: capturing, using a gesture input component of an information handling device, a user gesture input; processing, using a processor, the captured user gesture input to extract one or more features; comparing, using a processor, the one or more extracted features of the user gesture input to a predetermined gesture input; determining, using a processor, that a confidence level calculated based on the comparing exceeds a lower similarity threshold but does not exceed a higher similarity threshold; and performing an action selected from the group consisting of communicating with the user, and adjusting the gesture input component. Other aspects are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
capturing, using a gesture input component of an information handling device, a user gesture input within a field of view of the gesture input component;
comparing, using a processor, the user gesture input to a database comprising a plurality of predetermined gesture inputs;
identifying, using the processor, a lower similarity threshold associated with one of the plurality of predetermined gesture inputs and a higher similarity threshold associated with the one of the plurality of predetermined gesture input;
determining, based on the comparing, whether a confidence level calculated based on the comparing exceeds the lower similarity threshold or the higher similarity threshold, wherein the confidence level required to exceed the lower similarity threshold is dictated by a likelihood that the user gesture input is similar to a non-gesture input and wherein the confidence level required to exceed the higher similarity threshold is dictated by a performance cost of a system of the information handling device to undo an action resulting from user gesture input;
providing, responsive to determining that the confidence level exceeds the lower similarity threshold but not the higher similarity threshold, a tutorial comprising a modification suggestion for an aspect of the user gesture input to produce an intended predetermined gesture input; and
executing, responsive to determining that the confidence level exceeds the higher similarity threshold, a function corresponding to the user gesture input.

2. The method of claim 1 , wherein the comparing comprises comparing one or more extracted features of the user gesture input, wherein the one or more extracted features of the user gesture input are selected from the group consisting of shape of an object forming a user gesture; distance between an object forming the user gesture and the gesture input component; lighting condition of the captured user gesture input; and distractions included in the captured user gesture input.

3. The method of claim 1 , further comprising
automatically performing a predetermined action associated with the user gesture input if the user gesture input achieves the predetermined level of similarity with the predetermined gesture input.

4. The method of claim 1 , further comprising actively soliciting further user input responsive to the determining.

5. The method of claim 4 , wherein the actively soliciting comprises prompting a user to confirm a predetermined action.

6. The method of claim 1 , further comprising providing suggestive feedback to the user on how to properly perform the predetermined gesture input.

7. The method of claim 6 , wherein the suggestive feedback comprises information associated with one or more extracted features of previously captured gesture inputs that did not obtain the predetermined level of similarity with the predetermined gesture input.

8. An information handling device, comprising:
a gesture input component;
a processor operatively coupled to the gesture input component;
a memory device that stores instructions accessible to the processor, the instructions being executable by the processor to:
capture, using the gesture input component of an information handling device, a user gesture input within a field of view of the gesture input component;
compare the user gesture input to a database comprising a plurality of predetermined gesture inputs;
identify a lower similarity threshold associated with one of the plurality of predetermined gesture inputs and a higher similarity threshold associated with the one of the plurality of predetermined gesture input;
determine, based on the comparing, whether a confidence level calculated based on the comparing exceeds the lower similarity threshold or the higher similarity threshold wherein the confidence level required to exceed the lower similarity threshold is dictated by a likelihood that the user gesture input is similar to a non-gesture input and wherein the confidence level required to exceed the higher similarity threshold is dictated by a performance cost of a system of the information handling device to undo an action resulting from user gesture input;
provide, responsive to determining that the confidence level exceeds the lower similarity threshold but not the higher similarity threshold, a tutorial comprising a modification suggestion for an aspect of the user gesture input to produce an intended predetermined gesture input; and
execute responsive to determining that the confidence level exceeds the higher similarity threshold, a function corresponding to the user gesture input.

9. The information handling device of claim 8 , wherein the instructions executable by the processor to compare comprise instructions executable by the processor to compare one or more extracted features of the user gesture input, wherein the one or more extracted features of the user gesture input are selected from the group consisting of shape of an object forming a user gesture; distance between an object forming the user gesture and the gesture input component; lighting condition of the captured user gesture input; and distractions included in the captured user gesture input.

10. The information handling device of claim 8 , wherein the instructions are further executable by the processor to automatically perform a predetermined action associated with the user gesture input if the user gesture input achieves the predetermined level of similarity with the predetermined gesture input.

11. The information handling device of claim 8 , wherein the instructions are further executable by the processor to actively solicit further user input responsive to the determining.

12. The information handling device of claim 11 , wherein the instructions executable by the processor to actively solicit comprise instructions executable by the processor to prompta user to confirm a predetermined action.

13. The information handling device of claim 8 , wherein the instructions are further executable by the processor to provide suggestive feedback to the user on how to properly perform the predetermined gesture input.

14. The information handling device of claim 13 , wherein the suggestive feedback comprises information associated with one or more extracted features of previously captured gesture inputs that did not obtain the predetermined level of similarity with the predetermined gesture input.

15. A product, comprising:
a storage device having processor executable code stored therewith, the code comprising:
code that captures, using a gesture input component of an information handling device, a user gesture input within a field of view of the gesture input component;
code that compares, using a processor, the user gesture input to a database comprising a plurality of predetermined gesture inputs;
code that identifies, using the processor, a lower similarity threshold associated with one of the plurality of predetermined gesture inputs and a higher similarity threshold associated with the one of the plurality of predetermined gesture input;
code that determines, based on the comparing, whether a confidence level calculated based on the comparing exceeds the lower similarity threshold or the higher similarity threshold , wherein the confidence level required to exceed the lower similarity threshold is dictated by a likelihood that the user gesture input is similar to a non-gesture input and wherein the confidence level required to exceed the higher similarity threshold is dictated by a performance cost of a system of the information handling device
