Techniques are described for automatically assessing and using a user's handwritten input on a computing device to modify further user interactions, such as to dynamically adapt additional information that is presented to reflect an automatically assessed knowledge level of the user for a given subject area, and/or to dynamically adapt a user interface on the computing device to reflect an automatically assessed amount of energy expenditure of the user in producing the handwritten input. The techniques may include assessing the total energy expenditure of a user in producing handwritten input, by measuring and evaluating metadata about the handwritten input such as multiple stroke-level signal features, and combining them to determine an assessed total energy expenditure of a user, and may further include automatically assessing a knowledge level of the user for a subject area of the handwritten input based on the assessed total energy expenditure of the user. |

1. A computer-implemented method comprising:
presenting, to a user of a configured computing device and on a display screen of the configured computing device, initial information that includes one or more questions related to a specified subject area; receiving, by the configured computing device, responses to the one or more questions that are handwritten by the user on a touch-sensitive input area of the configured computing device; determining, by the configured computing device, multiple stroke signal features of the handwritten responses that include stroke pressure and stroke distance; determining, by the configured computing device and based at least in part on the determined multiple stroke signal features, a total amount of energy expended by the user in creating the handwritten responses; assessing, by the configured computing device and based at least in part on the determined total amount of energy expended, one of multiple levels of knowledge of the user for the specified subject area, wherein the assessing is performed without using information about accuracy of the handwritten responses and is based at least in part on a comparison to other amounts of energy expended by a plurality of other users in providing other handwritten responses to the one or more questions; determining, by the configured computing device and based at least in part on the assessed level of knowledge of the user for the specified subject area, to alter additional information presented to the user for the specified subject area; and presenting, by the configured computing device and to the user on the display screen, the altered additional information related to the specified subject area. |
