This document describes tools for inputting data into a computer via the movement of features of a user as detected by a webcam or other input device. This is accomplished by a user moving his or her features in view of a webcam. The webcam or other input device then detects the presence and motion of the feature s and converts these motions into input signals to execute predetermined input instructions. However, inputting information in a computer can be tedious and, for some, even painful.
Specifically, some computer users experience painful medical issues from the repetitive action of typing on a keyboard. In other cases it may be impossible to input data via a keyboard. For instance, a person who lacks full use of his or her hands may face significant obstacles inputting data via a keyboard. Thus, there is a need to input data via other means. This document describes tools for allowing a user to input data into a computer via movement of the user. For instance, the user may input data by moving his or her features e.
The webcam or other input device then detects presence and motion of the user and converts this detected movement into input signals to execute predetermined input instructions. In some instances, the tools accomplish these tasks without any remote control or sensing device attached to the user. These tools thus provide a novel method to write text characters, draw, control games, or otherwise perform actions that can supplement or replace inputs made via the traditional keyboard and mouse.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The detailed description is described with reference to accompanying figures. In the figures, the left-most digit s of a reference number identifies the figure in which the reference number first appears.
The use of the same reference numbers in different figures indicates similar or identical items. While these figures depict creation of a text character, it is to be appreciated that the described techniques may apply equally to any other type of user input, as described throughout.
