ALS is a progressive and incurable disease that gradually restricts physical functions while preserving consciousness, thought processes, and auditory functions. This study proposes a BMI-controlled augmented body system as a means for individuals with ALS to externally express their emotions and intentions despite severe physical limitations. Specifically, we co-designed and implemented a BMI-operated robotic arm with an ALS patient, using auditory stimuli to acquire brain potentials, enabling robotic arm control even in the late stages of the ALS. As a result, the user successfully manipulated the robotic arm at his intended timing, facilitating non-verbal communication such as clapping gestures and waving. This paper presents the system, insights gained from its implementation, and discusses future challenges and considerations.
