Patent ID: 7645226

Claim:
A method of inducing a relaxation state in a user, the method comprising: receiving a first input from a first color control, wherein the first color control provides user selection of the pulse width of a first rectangular wave; receiving a second input from a second color control, wherein the second color control provides user selection of the pulse width of a second rectangular wave; receiving a second input from a brightness control, wherein the brightness control provides user variation of the repetition rate of the first rectangular wave thereby forming a first amplitude modulated signal and provides user variation of the repetition rate of the second rectangular wave thereby forming a second amplitude modulated signal; emitting a first light beam from a first light source toward a first eye of a user, the first light beam having a first color and generated from the first amplitude modulated signal; emitting, simultaneous with the first light beam, a second light beam from a first light source toward the first eye of the user, the second light beam having a second color and generated from the second amplitude modulated signal, wherein the second color is different from the first color; and providing a first combined color perceived by the first eye of the user from the first light beam and the second light beam wherein the first color control and the second color control provide user control of the first combined color, and the brightness control provides user control of the brightness of the first combined color.
