Create a demo of facial gesture control using rule-based logic

[gutzcha]

Demonstrate the feasibility of the project using rule-based logic.
Implement the following functionalities

Zoom in/out:

• when the left eye is closed for more than 1 second, enter zoom mode
• while the left eye is closed, opening the mouth triggers zoom in
• opening the left eye for less than 2 seconds enables you to close your mouth without zooming out, but does not exit Zoom mood
• closing the left eye again re-tethers mouth to zoom
• opening the left eye and keeping it open for 2 seconds exists Zoom mode.

Scroll up/down:

• frowning (lowering eyebrows) for more than 1-second enters the scroll-down mode
• fast eyebrows downward movement scrolls down
• extended frowning down for more than 1-second disconnects between brow movement and scrolling down.
• the same for scrolling up, but lifting eyebrows instead of lowering

• Zoom mode implementation
• Scroll mode implementation
• Create a demo video
