Sensory Stimulation Therapy Device Using LCD Sunglasses

A sensory stimulation therapy device using LCD sunglasses for preventing and treating neurological disorders involving impairment of functional connectivity of brain and provided with a structure enabling a subject of treatment to visually perceive a surrounding environment during treatment action, wherein

• the sensory stimulation therapy device comprises a visual stimulator, an auditory stimulator, and an audio-visual control device,
• the visual stimulator is LCD sunglasses that generate light stimulation by controlling transmittance of light incident from the surrounding environment transmitted through an LCD element by placing the LCD element as a lens of 2 eyes or wide 1 eye LCD sunglasses,
• the auditory stimulator is a sound-emitting device that generates sound stimulation on an audible frequency, and
• the audio-visual control device is control means that generates the light stimulation by supplying an applied voltage to the LCD element, generates the sound stimulation by supplying a drive signal to the sound-emitting device, and controls a phase difference Δθ from the light stimulation to the sound stimulation,
• sets, as a timing B representative of a phase of the light stimulation, an instant of zero-crossing as a fundamental frequency component of a waveform pattern of the transmittance repeatedly generated by the LCD element increases, and
• supplies the drive signal to the sound-emitting device at a timing C shifted from the timing B by the phase difference Δθ.
