Abstract
Methods and apparatuses to detect configuration commands from waveforms received at a retina prosthesis device for calibrating the device are described. The device can comprise an array of pixel units to receive light to stimulate neuron cells to cause an effect of visual sensation from the light. The pixel units may have configurable parameters for the stimulation to the neuron cells. The configurable parameters may be updated according to the configuration commands detected without requiring micro processor and non-volatile memory in the device. The stimulation may be generated according to the updated configurable parameters to improve the effect of visual sensation from the light including compensation for the physiological and environmental variations and drifts.
