Abstract
A apparatus for detecting electrooculograph (EOG) signals, comprising: a pair of temple pieces connected to a bridging structure; at least one electrode on each temple piece configured to contact the skin at the temple, and to receive an EOG signal from a proximate orbital socket; a reference electrode displaced from each temple; and a processor configured to process signals from the sensors to detect saccade movements of the eyes. A wavelet-based algorithm permits analysis and coding of the saccade movements.
Claims20
An apparatus for detecting electrooculograph (EOG) signals, comprising:
- a pair of temple pieces connected to a bridging structure;
- at least one electrode on each temple piece configured to contact the skin at the temple, and to receive an EOG signal from a proximate orbital socket;
- a reference electrode displaced from each temple;
- and
- a processor configured:
- to process signals from the at least one electrode on each temple piece and the reference electrode to detect saccade movements of the eyes;
- and
- characterize a sequence of states of the received EOG signal as a single user command selected from a wordbook of valid user commands.
A method for detecting electrooculograph (EOG) signals, comprising:
- providing a pair of temple pieces connected to a bridging structure to a human or animal, having at least one electrode on each temple piece configured to contact the skin at the temple, and to receive an EOG signal from a proximate orbital socket and a reference electrode displaced from each temple;
- processing electronic signals from the at least one electrode on each temple piece to detect saccade movements of the eyes;
- and
- characterizing a sequence of a plurality of amplitudes and signs of the EOG signal over a period of time as a single user command selected from a wordbook of valid user commands.
A method for detecting electrooculograph (EOG) signals from eyes of a human or animal, comprising:
- providing a pair of temple pieces connected to a bridging structure supported by a nose of the human or animal, having at least one electrode on each temple piece configured to contact the skin at the temple, substantially without contacting an infraorbital facial surface, and to receive an EOG signal from a proximate orbital socket and a reference electrode displaced from each temple;
- processing electronic signals from the at least one electrode on each temple piece and the reference electrode to characterize an amplitude and direction of saccadic movements of the eyes and fixation of the eyes;
- and
- interpreting sequences comprising a plurality of characterized amplitudes and directions of saccadic movements of the eyes and fixations of the eyes over a period of time as a single user command selected from a wordbook of valid user commands.
