Patent number: 10551915Abstract: According to the invention, a method for entering text into a computing device using gaze input from a user is disclosed. The method may include causing a display device to display a visual representation of a plurality of letters. The method may also include receiving gaze information identifying a movement of the user's gaze on the visual representation. The method may further include recording an observation sequence of one or more observation events that occur during the movement of the user's gaze on the visual representation. The method may additionally include providing the observation sequence to a decoder module. The decoder module may determine at least one word from the observation sequence representing an estimate of an intended text of the user.Type: GrantFiled: August 22, 2018Date of Patent: February 4, 2020Assignee: Tobii ABInventors: Per Ola Kristensson, Keith Vertanen, Morten Mjelde

Publication number: 20160062649Abstract: A system, method and computer-readable medium that previews words and commands recognized by a continuous stroke recognizer based on input into a virtual keyboard layout is presented. The system and method allows a user to see the word that will be recognized or output before the user commits the continuous stroke input to the system. Further, after recognition and output, the system presents the recognized output word and the closest word candidates in a correction display integrated with the virtual keyboard layout. Among other things, the user is provided with options to change the current output word by selecting another word candidate on the correction display, and to delete the current output word by selecting the representation of the current output word on the correction display.Type: ApplicationFiled: September 3, 2015Publication date: March 3, 2016Inventor: Per Ola Kristensson

Patent number: 9256580Abstract: A word pattern recognition system improves text input entered via a shorthand-on-keyboard interface. A core lexicon comprises commonly used words in a language; an extended lexicon comprises words not included in the core lexicon. The system only directly outputs words from the core lexicon. Candidate words from the extended lexicon can be outputted and simultaneously admitted to the core lexicon upon user selection. A concatenation module enables a user to input parts of a long word separately. A compound word module combines two common shorter words whose concatenation forms a long word.Type: GrantFiled: March 12, 2014Date of Patent: February 9, 2016Assignee: Nuance Communications, Inc.Inventors: Per-Ola Kristensson, Shumin Zhai
