Scoring predictions based on prediction length and typing speed
View Patent ↗A method that includes receiving an input, determining, by the processor, a likelihood that a predicted string associated with the received input matches an intended input string, where the determination is a function of at least one of a length of the predicted string and a typing speed associated with the received input, and displaying the predicted string.
1. An input method for a communication device having a hardware processor, the method comprising:
receiving, through a virtual keyboard displayed on a touchscreen of the communication device, an input string;
determining a typing speed associated with the received input;
generating, by the hardware processor, predicted strings stored in a dictionary memory of the communication device, where contextual data is sued when generating the predicted string;
assigning, by the hardware processor, a higher likelihood to longer predicted strings associated with the received input matches an intended input string when a typing speed associated with the received input increases;
assigning, to the predicted string, a score associated with the determined likelihood, wherein the score is independent of the length of the predicted string if the typing speed is below a predetermined speed threshold;
determining whether to display the predicted string based at least on the score;
displaying, on virtual keyboard of the communication device, one or more predicted strings at or near the input string and based on the determined likelihoods of the predicted strings; and
determining, by the hardware processor, whether one of the predicting strings matched the intended input string based on user input or omission of user input within a predetermined period of time.
2. The method of claim 1 , further comprising decreasing the score if the difference between the length of the predicted string and the length of the input is smaller than a length threshold.
3. The method of claim 1 , wherein the length threshold is a function of a reaction time.
4. The method of claim 1 , wherein the length threshold is a function of the typing speed.
5. The method of claim 1 , wherein the length threshold is in direct relationship with the typing speed.
6. The method of claim 1 , further comprising measuring the typing speed by calculating an average typing speed across a predetermined number of input characters.
7. An electronic device comprising a display and a hardware processor, the hardware processor configured to perform:
receiving, through a virtual keyboard displayed on a touchscreen of the communication device, an input string;

assigning, by the hardware processor, a higher likelihood to longer predicted strings associated with the received input matches an intended input string when a typing speed associated with the received input increases;
assigning, to the predicted string, a score associated with the determined likelihood, wherein the score is independent of the length of the predicted string if the typing speed is below a predetermined speed threshold;
determining whether to display the predicted string based at least on the score;
displaying, on virtual keyboard of the communication device, one or more predicted strings at or near the input string and based on the determined likelihoods of the predicted strings; and
determining, by the hardware processor, whether one of the predicting strings matched the intended input string based on user input or omission of user input within a predetermined period of time.
