When looking at movies and games, jumpjets/jetpacks are often easy to control. In games its a matter of a keyboard press away and in movies it more or less does exactly what the person asks of it, often without an explanation of how or with the simple explanation of neural link.

I'm working on a story with a jumpjet. For ease of use this jumpjet stabilizes itself in an upright position and the owner only needs to focus on up, down, left, right, forwards backwards, if possible this is analogue so you can go diagonal at any angle of these options. The problem is: when these jetpacks are necessary elaborate electrical systems dont work. Ignoring the difficulty of stabilizing the jumpjet the actual controls are now a lot more difficult. I cant use the magic neural link and say "it just works". I need a solid control mechanism.

Small edit: I'll be using a game/movie jumpjet rather than the miniature vehicles we have in real life.

A compounding problem is that this jumpjet needs to be operated while the hands are occupied (say carrying a child or handling tools or weapons, ignoring again the difficulty if stabilization or fuel usage when thrusters at your chest are mostly blocked). So you cant use two joysticks (which would not be elaborate enough and still work). This leaves me wondering: what kind of system could I use to control this jumpjet?

The best answer would require the least thought of the user, while hindering the user as little as possible while controlling his/her jumpjet.
