US Patent 10007335 User interface selection based on user context

Technologies are generally described to provide alternate user interfaces based on user context. In some examples, a user interface system may measure a user characteristic associated with a particular user interface type. The user interface system may then determine whether the measured user characteristic is suitable for use as a user interface input, for example by comparison with a baseline user characteristic. Upon determination that the measured user characteristic is suitable, the user interface system may use the measured user characteristic for user interface purposes. On the other hand, upon determination that the measured user characteristic is not suitable, the user interface system may use a different user interface type to attempt to receive user inputs.
