Aren't physical buttons that you can feel with your touch safer than touch screens?

Aren't physical buttons that you can feel with your touch safer than touch screens?
- tdy721 6y agoNot if they weigh so much you don’t make 11.2km/s
- hanniabu 6y agoAlso there's the adaptability aspect. For manual controls you'd need a ton of physical controls and you need the astronauts to know them by heart. With a screen that has an adaptable interface it's much easier UX on the astronaut as the controls increase. Also I'm sure ground control can push an emergency update if need be where you wouldn't quite have that luxury with manual controls.
- meritganset 6y agoDo you even understand the statement you're making? By your account, the astronauts to knowing the controls of the spacecraft by heart is a negative. You honestly believe that a CHANGING INTERFACE is less of a cognitive load on an astronaut than a fixed, tactile one? You also then must believe that we're sending human being s into space without them knowing the controls of the vehicle by heart. Does your mental model of spaceflight coincide with what it's like to learn how the HVAC works a new car when you buy it from the dealership? Astonishing.
- meritganset 6y agoYou're right. If I remember correctly, we've never made it to space with physical controls. They probably weigh too much.
- elif 6y agoI don't think so. an interactive UI can have context-dependent actions, confirmation dialogs, disable access to buttons, etc. When what is happening is basically an artificial computer process with human overrides, It could be a little disingenous to have a physical switch. For instance: imagine there's some pump that the computer won't let you disable because disabling it would cause an explosion. You are in an emergency and flip a switch intending to disable it. You now don't know the internal state of the process... whether the switch flip did what you intended or not.

- rtkwe 6y agoThey have physical buttons for super critical stuff like aborts (the large handle between seats 2 and 3 in the center and deploying parachutes along the bottom below the touch screen. Touchscreens cuts down on the weight and space requirements a lot too and interfaces can adapt to include more or less information as the mission demands.
