Abstract

Detecting user input based on multiple gestures is provided. One or more interactions are received from a user via a user interface. An inferred interaction is determined based, at least in part, on a geometric operation, wherein the geometric operation is based on the one or more interactions. The inferred interaction is presented via the user interface. Whether a confirmation has been received for the inferred interaction is determined.

First claim

What is claimed is:

1. A method comprising:
receiving, by one or more processors of a set of processor(s), one or more interactions from a user via a user interface;
determining, by one or more processors of the set of processor(s), an inferred interaction based, at least in part, on a geometric average of coordinate dimensions of the one or more interactions, one or more weights based on a closeness of the coordinate dimensions to an edge of the user interface, and statistical information corresponding to the user interface;
presenting, by one or more processors of the set of processor(s), the inferred interaction via the user interface;
determining, by one or more processors of the set of processor(s), whether a confirmation has been received for the inferred interaction;
receiving, by one or more processors of the set of processor(s), one or more additional interactions from the user via the user interface; and
updating, by one or more processors of the set of processor(s), the inferred interaction based on a geometric average of the coordinate dimensions of the one or more interactions and coordinate dimensions of the one or more additional interactions, one or more weights based on a closeness of the coordinate dimensions of the one or more additional interactions to an edge of the user interface, and additional statistical information corresponding to the user interface.

2. The method of claim 1 , further comprising:
in response to determining that the confirmation has been received for the inferred interaction, determining that the confirmation is a positive confirmation; and
in response to determining that the confirmation is a positive confirmation, performing, by one or more processors of the set of processor(s), the inferred interaction.

3. The method of claim 1 , wherein presenting the inferred interaction comprises:
determining, by one or more processors of the set of processor(s), a probability that the inferred interaction is an interaction intended by the user; and
in response to determining, by one or more processors of the set of processor(s), that the probability is above a pre-determined threshold, presenting, by one or more processors of the set of processor(s), the inferred interaction via the user interface.

4. The method of claim 1 , wherein determining whether the confirmation has been received for the inferred interaction is based, at least in part, on receiving, by one or more processors of the set of processor(s), no interactions via the user interface for a pre-determined time period.

5. The method of claim 1 , wherein determining whether the confirmation has been received for the inferred interaction includes:
identifying, by one or more processors of the set of processor(s), the inferred interaction via the user interface;
presenting, by one or more processors of the set of processor(s), an interface element via the user interface, the interface element prompting the user for the confirmation of the inferred interaction; and
receiving, by one or more processors of the set of processor(s), an interaction via the interface element.

6. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
receiving one or more interactions from a user via a user interface;
determining an inferred interaction based, at least in part, on a geometric average of coordinate dimensions of the one or more interactions, one or more weights based on a closeness of the coordinate dimensions to an edge of the user interface, and statistical information corresponding to the user interface;
presenting the inferred interaction via the user interface;
determining whether a confirmation has been received for the inferred interaction;
receiving one or more additional interactions from the user via the user interface; and
updating the inferred interaction based on a geometric average of the coordinate dimensions of the one or more interactions and coordinate dimensions of the one or more additional interactions, one or more weights based on a closeness of the coordinate dimensions of the one or more additional interactions to an edge of the user interface, and additional statistical information corresponding to the user interface.

7. The computer program product of claim 6 , wherein the method further comprises:
in response to determining that the confirmation has been received for the inferred interaction, determining that the confirmation is a positive confirmation; and
in response to determining that the confirmation is a positive confirmation, performing the inferred interaction.

8. The computer program product of claim 6 , wherein the method further comprises:
determining a probability that the inferred interaction is an interaction intended by the user; and
in response to determining that the probability is above a pre-determined threshold, presenting the inferred interaction via the user interface.

9. The computer program product of claim 6 , wherein determining whether the confirmation has been received for the inferred interaction is based, at least in part, on receiving no interactions via the user interface for a pre-determined time period.

10. A computer system comprising:
a memory; and
a processor in communication with the memory, wherein the computer system is configured to perform a method, the method comprising:
receiving one or more interactions from a user via a user interface;
determining an inferred interaction based, at least in part, on a geometric average of coordinate dimensions of the one or more interactions, one or more weights based on a closeness of the coordinate dimensions to an edge of the user interface, and statistical information corresponding to the user interface;
presenting the inferred interaction via the user interface;
determining whether a confirmation has been received for the inferred interaction;
receiving one or more additional interactions from the user via the user interface; and
updating the inferred interaction based on a geometric average of the coordinate dimensions of the one or more interactions and coordinate dimensions of the one or more additional interactions, one or more weights based on a closeness of the coordinate dimensions of the one or more additional interactions to an edge of the user interface, and additional statistical information corresponding to the user interface.

11. The computer system of claim 10 , wherein the method further comprises:
in response to determining that the confirmation has been received for the inferred interaction, determining that the confirmation is a positive confirmation; and
in response to determining that the confirmation is a positive confirmation, performing the inferred interaction.

12. The computer system of claim 10 , wherein the method further comprises:
determining a probability that the inferred interaction is an interaction intended by the user; and
in response to determining that the probability is above a pre-determined threshold, presenting the inferred interaction via the user interface.

13. The computer system of claim 10 , wherein determining whether the confirmation has been received for the inferred interaction is based, at least in part, on receiving no interactions via the user interface for a pre-determined time period.
