We examine a method of decision judgment using Event-Related Potential P300 in Communication Aid (CA) for those who have motor neuron disease, ALS (Amyotrophic Lateral Sclerosis). Taking a practical situation into consideration, we try to extract the signal about P300 under not a shield but a usual room and by a single trial. We propose to evaluate the exact decision of the user who may hope something for someone. Introducing an improved Oddball Paradigm and appropriate moving averaging, we can realize the extraction of the wave of P300 under a usual room and by a single trial. Applying a modeled wave form with quantitative conditions used in clinical diagnosis, we can obtain successful results with a higher ratio in judgment about users' decision.
