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.

Claims

1. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, 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, wherein the one or more interactions include a touch gesture performed on a touch screen;

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;

determining a probability that the inferred interaction is an interaction intended by the user;

in response to determining that the probability is above a pre-determined threshold, presenting the inferred interaction via the user interface;

determining whether a confirmation has been received for the inferred interaction by identifying the inferred interaction via the user interface, presenting an interface element via the user interface, the interface element prompting the user for the confirmation of the inferred interaction, and receiving an interaction via the interface element;

in response to determining that the confirmation has been received for the inferred interaction, determining that the confirmation is a positive confirmation;

in response to determining that the confirmation is a positive confirmation, performing 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.
