Somia - dream without end

Description

A language learning app that helps user learn vocabulary during their sleep. Require sleep tracker gadget.

Origin of the name

The name came from latin word 'somnia', removing the character n to express dream without n (end).

As a name, Somia is believed to makes the owner a quick thinker, both philosophical and creative.

Color Scheme

The application use 2 main color: Black as the background, and Blue as the highlight.

In a dream, Black symbolizes the unknown, the unconscious while Blue represents truth, wisdom, eternity, devotion.

Black and Blue also have the same initial B. It's cooler that way!

The Inspiration

The sleeping child outplays the adult's capacity to convert implicit into explicit knowledge. Researches showed that as a child, we learn things subconsciously even during sleep.

A good night's sleep triggers changes in the brain that help to improve memory. ref

Study Shows How Sleep Improves Memory shows that A good night's sleep triggers changes in the brain that help to improve memory, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).

Rule: From a famous experiment in subconscious learning. Only play audio of foreign words you’ve already heard, and set the audio to run for the first two to three hours of sleep. When you wake, give yourself a quiz to test your recall.

The design

  • Sleep tracking – detect sleeping status
  • Music therapy – good for sleep music
  • Vocabulary audio – reinforce knowledge • Quiz – check progress
  • Quiz – check progress
  • Audio sync with brain wave (theta wave)
  • There are 3s gap between sounds
  • App check continuously for 10 min stable period

Sleep Tracking Technology

We track the user's sleep status by 3 steps:

  1. User body/muscle movements are recorded via accelerometer sensor of smartphone/smart-wearable.
  2. Data are sampled down using the mean of maximum and minimum points and recorded as discrete time series.
  3. Statistically analyzed in comparison with provided collected samples to decide if user is sleeping.

The samples are collected during the Edtech Hackathon 2016.

Final notes

We have some origami flowers at our table available for giving away~

The researchers added a techie dimension by conducting electroencephalographic (EEG) recordings of the sleeping participants’ brains to track neural electrical activity during the learning period. They found that learning the foreign words overlapped with the appearance of theta brain waves, an intriguing result since theta is the brain wave state often associated with heightened learning while awake

Frequency range, Name, Usually associated with:

Higher than 40 Hz, Gamma waves, Higher mental activity, including perception, problem solving, fear, and consciousness

13–39 Hz, Beta waves, Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia

7–13 Hz, Alpha waves, Relaxation (while awake), pre-sleep and pre-wake drowsiness, REM sleep, Dreams

8–12 Hz, Mu waves Mu rhythm, Sensorimotor rhythm

4–7 Hz, Theta waves, Deep meditation/relaxation, NREM sleep

Lower than 4 Hz, Delta waves, Deep dreamless sleep, loss of body awareness

This binaural beats session will stimulate the Delta Wave frequency spectrum.
