Human brain consists of left brain and right brain. The function of left brain is different from the right brain. The left brain controls apparent consciousness while the right brain control subconscious. Findings from research of brain development shows that the right brain is the "treasure house" of children's intelligence. From current tfinding we can also learn that the right brain possesses 5 major functions described below.

• Preserving zone for sagacity inherited from our ancestors
• Stimulating zone for unconsciousness thinking
• Working zone for highly efficient metabolism
• Controlling zone for deliberate complex
• Exploring zone for creativeness

The soul of creation lies in the right brain because the right brain is many times more powerful thant the left one. The right brain is highly efficient in information processing thus possesses excellent creative capability.

The period around 6 years old is the most critical period for brain education. During this period, thinking focused on the archicortex will be turned into subconscious intuitive memory focused on the neocortex. Then intuitive memory will be turned into reasoning memory and intuitive thinking will be substituted by reasoning thinking. Chilhood is the period for intelligence development and with appropriate training, children will possess great creativeness, dedication to work and good interpersonal skill when they grow up.

In addition, studies show that when a person is focused on a task whether studying, working or performing, strong a (alpha) wave are sent off by the brain. As soon as the pre-condition for the a wave is created,  people can overcome difficulties and double their learning capability

Since 1930, the scientists have been applying the brain wave theory to study the influences of light wage and sound wave of different frequency on the activity of the human brain. Applied to medical treatment, these researches  have lead to the development of numerous devices used to diagnose and treat malajusted brain. With the use of microcomputer technology, these devices are now a lot less expensive. In Korea, it has become a kind of learning assistant known in every household.

The potential development device has six major functions:

• Develop potential of the right brain, stimulate creativeness
• Relaxing, remove strain, anxiety, stabilize mood and regulate the body and the mind
• Strenghten concentration and memory, improve efficiency in learning and working
• Remove nervousness prior to examination or competition, improve performance
• Ease the symptom of insomnia, improve quality of sleep
• Stimulate vitality, hearthen the spirit, regulate the body and mind to peak state

• Press Music key to select background music.
• Press Audio key to increase or decrease the volume of the frequency sound.
• Press Background Volume keys to increase or decrease the volume of background music. Left key will increase while the right key will decrease the volume.
• Press Visual Acuity keys to increase or decrease the intensity of the light in the spectacles. Left key will increase while the right key will decrease the intensity.
• Close your eyes and relax to adjust your body and mind.

• If batteries are running out, the device will stop working and beep.

• To eager to see results, making you feel nervous and achieving negative result.
• Failure to use the device consistently, hoping to get it done once and for ever. Don't expect any miracles after one or two uses.
• Wrong use of the programs, achieving no result at all.
• To seek for immediate result by using too strong volume and brightness intensity.
• Eyes are not closed while putting on spectacles
• No deep breath prior to use.
