Abstract

Data for detected events and predicted events, associated with a user device, are stored. The detected events may be associated with inputs received via the user device, and the predicted events may represent predicted future inputs to the user device. The predicted events may be evaluated to identify an erroneous predicted event, such as a predicted event that differs significantly from a corresponding detected event or a predicted associated with a time period when no corresponding detected event occurs. The erroneous predicted events and set of other prior predicted events are selected to be discarded. For example, the selected set of prior predicted events to discard may be associated with a period of time corresponding to the erroneous predicted event. Instructions may be sent to applications executed by the user device to disregard the selected predicted events.

Claims20

Dependent claims

A device comprising:

a memory configured to store:
data corresponding to a first detected event associated with a first input received by a user device and data corresponding to a second detected event associated with a second input received by the user device, and
data associated with a plurality of predicted events that are generated based on the first detected event and that predict inputs received by the user device, wherein each predicted event is associated with a corresponding prediction time;
and
a processor configured to:
determine whether the second detected event that corresponds to one of the predicted events occurs during the prediction time of the one of the predicted events,
determine that the one of the predicted events is invalid based on a determination that the second detected event and the corresponding one of the predicted events differ by a predetermined threshold,
select predicted events from the plurality of predicted events based on determining that the one of the predicted events is invalid, wherein the selected predicted events are associated with the prediction times that occur before the prediction time of the one of the predicted events, and
cause the selected predicted events to be discarded.

A method comprising:

determining, by a processor, whether a second detected event that corresponds to one of a plurality of predicted events occurs during a prediction time of the one of the plurality of predicted events, wherein the plurality of predicted events are generated based on a first detected events and predict input received b a user device, and wherein each predicted event is associated with a corresponding prediction time;
determining, by a processor, that one of the plurality of predicted events is invalid based on a determination that the second detected event and the corresponding one of the predicted events differ by a predetermined threshold;
selecting, by the processor, predicted events from the plurality of predicted events based on determining that the one of the predicted events is invalid, wherein the selected predicted events are associated with the prediction times that occur before the prediction time of the one of the predicted events;
and
causing, by the processor, the selected predicted events to be discarded.

2 more elements

A non-transitory computer-readable medium to store instructions comprising:

one or more instructions that, when executed by a processor, cause the processor to:
determine whether a second detected event that corresponds to one of a plurality of predicted events occurs during a prediction time of the one of the plurality of predicted events, wherein the plurality of predicted events are enerated based on a first detected event and predict input received b a user device, and wherein each predicted event is associated with a corresonding prediction time
determine that one of the plurality of predicted events is invalid based on a determination that the second detected event and the corresponding one of the predicted events differ by a predetermined threshold;
select predicted events from the plurality of predicted events based on determining that the one of the predicted events is invalid, wherein the selected predicted events are associated with the prediction times that occur before the prediction time of the one of the predicted events;
and
cause the selected predicted events to be discarded.
