Abstract

Disclosed is an apparatus for inducing various brain wave patterns through visual stimulation. The apparatus comprises a pair of spectacles or other viewing apparatus having a liquid crystal display embedded in each lens. By repetitively activating and deactivating the liquid crystals, shadows are generated which are perceived by the subject individual wearing the viewing apparatus. Responding to the frequency of shadow generation, the subject'"'"'s brain is thereby induced to generate sympathetic brain wave frequencies. The apparatus finds particular utility in the generation of alpha waves. Because learning is enhanced when the brain is in the alpha state, activities such as listening to tapes or lectures and the like can be carried out with greater facility. Shadow generation is accomplished through the use of a timing mechanism for each liquid crystal display and the frequency for each is adjustable over a wide range, permitting synchronous or asynchronous timing.

Claims

1. A shadow generating apparatus, comprising:

a viewing apparatus;

at least a lens fitted to said viewing apparatus, each said lens having disposed therein a liquid crystal display;

a timing mechanism connected to said liquid crystal; and

a power source for said timing mechanism;

wherein said timing mechanism intermittently activates and deactivates said liquid crystal.

2. A shadow generating apparatus according to claim 1, wherein said timing mechanism is adjustable, causing said liquid crystal to open and close at frequencies between 1 and 6 cycles per second.

3. A shadow generating apparatus according to claim 2, wherein said timing mechanism in each said crystal is adjustable.

4. A shadow generating apparatus according to claim 3, where timing mechanism is positioned on said viewing apparatus within a timing pack.

5. A shadow generating apparatus according to claim 4, wherein said shadow generating apparatus has two lenses each having a liquid crystal display and timing mechanism and wherein said displays can be operated asynchronously.

6. A shadow generating apparatus according to claim 5, wherein each said liquid crystal occupies from about 1 inch by 1 inch to about 4 inches by 4 inches of said lens.

7. A shadow generating apparatus according to claim 6, wherein said apparatus is worn by a human subject and said timing mechanisms are adjusted to activate said liquid crystals at a frequency of between 1 and 6 cycles per second, thereby inducing the brain of said subject to emit alpha waves.

8. A shadow generating apparatus according to claim 4, wherein said apparatus is used to induce delta and theta waves in a human subject.
