It is estimated that nearly 17 million American are affected by ADHD. Several treatment methods have been used in the past. None of them, however, include the use of a mask that forces the user to concentrate his/her attention to a pre-defined area.

The Olsen invention is intended to help illiterates learn typing. (Why we need illiterate typists the patent doesn't explain.) It divides the keys of a typewriter keyboard into eight sectors, each including several individual keys. Each sector has a different colour. The would-be typist wears coloured rings on her fingers and watches a visual indicator, which shows a colour either with or without an arrow. Where there is no arrow, the typist presses her finger with the associated colour directly downwards. Where there is an arrow, the typist first moves the correct colour finger up, down or along one key in the direction of the arrow.

The invention relates to a humanoid interview robot used in the field of human resources (HR), which can conduct job interviews.

Communication with the candidate interviewed by the interview robot according to the invention is provided via camera (U1), microphone (U2), odor sensor (U3), speaker (U4) and touch sensors (U5). The camera (U1) is preferably mounted on the eye of the interview robot, microphone (U2) is mounted on the ears, odor sensor (U3) is mounted on its nose, speaker (U4) is mounted on its mouth, and touch sensors (U5) are mounted on its chin or synthetic skin. These elements enable the candidate to respond verbally or in writing to the questions asked to determine the utility functions for economic, social and environmental qualities by specifying his/her identity information.

Apart from their technical capabilities, U1, U2, U3, U4 and U5 elements are customized to collect all kinds of visual, auditory, tactile, etc. data about the candidate so as to include qualifications or competencies such as the candidate's appearance, his/her self-care treatment, stress status, etc. in the decision-making process.
