How does the Joystick Pad works?

Hello,
I'm a software engineer and working on a way to select and move objects in a 2D environment on a Touchscreen with very high accuracy.

In "Star Trek Voyager - Technical Guide Version 1.0" by Rick Sternback and Michael Okuda, page 16 (see 1) I came across the "Joystick Pad" that is used to navigate and possibily launch torpedos/fire phasers on board Voyager and the Enterprise in Star Trek Nemesis (see 2, time stamp 1:01 and following).

See 3 for a redrawn version of the control.

I am wondering how this (fictional) user interface control is supposed to work. I understand the horizontal and vertical scrollbars are used to do x and y translation (see 4, page 38). What functionality do the other buttons serve?

  1. What is the logic behind the control?
  2. Is there any reason why in the Nemesis scene Worf activates the left side of the control and suddenly the right side changes color to gray?
  3. Are there any thoughts behind lcars color coding in the show other than switching to red for a code red?
I would appreciate any response.

Best Regards,
Andreas
