Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for resolving erroneous movement signals and for providing navigation instructions. One of the methods includes receiving data from two or more sensors, synchronizing the received data, determining a first subset of the synchronized data from the camera for a particular period of time and a second subset of the synchronized data from the other sensor for the particular period of time, comparing the first subset with the second subset to determine whether the first subset and the second subset indicate an erroneous movement signal, based on determining that the first subset and the second subset indicate an erroneous movement signal, selecting data for one of the sensors based on a sensor priority scheme for the sensors, and resolving the erroneous movement signal based on the selected data for the one of the sensors.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing scanning options in user interfaces to facilitate the selection of input options in the provided user interface. In some implementations, a method may include displaying a first user interface including a first set of at least three scanning options. Also, the method may include receiving a selection of a first scanning option of the first set, and displaying a second user interface including a second set of scanning options based on the selection of the first scanning option. Further, the method may include receiving a selection of a first scanning option of the second set, and determining that the first scanning option of the second set defines a single input option that does not result in additional input options, and in response performing a command associated with the single input option.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a user device with a wearable device. One of the methods includes receiving, by a user device and from a wearable device, data sets that each represent a sequence of physical positions of the wearable device in response to movement of the wearable device, determining, for each data set, whether the data set indicates a predetermined sequence of positions of the wearable device, for only each data set determined to indicate a predetermined sequence of positions of the wearable device, determining a predetermined sequence of actions to perform on the user device that correspond with the predetermined sequence of positions, and for only each data set determined not to indicate a predetermined sequence of positions of the wearable device, not taking an action in response to the data set.
