10. Why is accessibility important?
We need to cater to their needs because,
- Narratives are much different from ours
- Different perspectives, diversity and thought
processes
As a content provider,
- Get increased audience & adoption
- Demonstrate social responsibility
- Satisfy existing and future legal requirements

engineers
fit in?

12. What is BCI?
12
➔ A Brain Computer Interface (BCI) is an interface in which a
person uses his/her brain to control the machine, this machine
can be a computer, wheelchair, robot, assistive or an alternative
communication device
➔ BCIs strive to decode brain signals into control commands for
severely handicapped people with no means of muscular control

14. Brain waves
14
Delta waves (0.1 - 4 Hz) : sleep and empathy
Theta waves(4 - 8 Hz) : Daydreaming, meditation,
creative ideas
Alpha waves(8 - 12Hz) : Alertness with eyes
closed, relaxed positive feelings
Beta waves(12 - 30 Hz) : Alertness with eyes
open
Gamma waves( >30 Hz) : Cognitive and motor
functions
