Frequently Asked Questions

  1. What is EMG/EEG and how do they work? Electromyography is controlling electrical activity in skeletal muscles. Through electroencephalography, we track the brain’s electrical activity through brain wave patterns. Using small metal disks that measure potentials across the scalp, we are able to get a reading of the brain’s signals.
  2. How are you utilizing EMG and EEG for this project? For the EEG, merely thinking of anything will produce brainwaves and these are then measured by the EEG and then translated to move the pong paddle. On the EMG side, flexing the bicep of an arm will provoke electrical activity and this muscle response is then taken in by the EMG controlling the other paddle of pong.
  3. Are girls or guys generally better at this?According to studies, generally girls would produce higher frequencies for delta, theta, alpha 2 and beta waves. Therefore on the EEG side, females would have more accurate readings for the Emotiv EPOC device to interpret. No statistical difference has been shown between female and male EMG results.
  4. What are the actual uses of the EMG and the EEG? EMG’s are used to detect possible muscular imbalances and abnormalities. EEG’s are similar to EMG’s however they are used to detect abnormalities pertaining to the brain.
  5. Would the EMG paddle be easier to use if you are more muscular? There is a relationship between muscular strength and the ability for the EMG to receive the signals from flexing.
