2-dimensional movement control is an interesting issue in Brain-Computer Interface. In this paper, we present a motor imagery based 2-D cursor control paradigm. To move the cursor to a random position, two-class motor imagery is simultaneously combined to output 2-D command, which directly points to target position. A center-out experiment (8 targets) is set to verify the proposed paradigm. The results of the online experiment (three subjects participated) validate the proposed strategy very well.

UI MeSH Term Description Entries
D009043 Motor Activity Body movements of a human or an animal as a behavioral phenomenon. Activities, Motor,Activity, Motor,Motor Activities
D009068 Movement The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior. Movements
D011336 Probability The study of chance processes or the relative frequency characterizing a chance process. Probabilities
D003198 Computer Simulation Computer-based representation of physical systems and phenomena such as chemical processes.

D019018 Imagery, Psychotherapy The use of mental images produced by the imagination as a form of psychotherapy. It can be classified by the modality of its content: visual, verbal, auditory, olfactory, tactile, gustatory, or kinesthetic. Common themes derive from nature imagery (e.g., forests and mountains), water imagery (e.g., brooks and oceans), travel imagery, etc. Imagery is used in the treatment of mental disorders and in helping patients cope with other diseases. Imagery often forms a part of HYPNOSIS, of AUTOGENIC TRAINING, of RELAXATION TECHNIQUES, and of BEHAVIOR THERAPY.
