The sense of taste allows you to feel the fresh blood surging to your mouth after being injured, creating a stronger sense of life and death crisis, stimulating the brain to secrete more hormones...
The sense of touch can perceive the flow of air, the aggression of the body, the texture feedback of melee weapons hitting the enemy...
These are additional information that vision and hearing cannot provide.
Touch is particularly important.
Let me give you the simplest example.
At the Third Level, Ren Zhong picked up an apple using the exoskeleton gloves.
He didn't have an accurate force feedback on his hand and could only leave the force control to the armored assistant brain.
The assistant brain must first identify the type of the target object, then combine it with his operational intention, conduct some calculations, and finally give an accurate enough output power, deciding whether the apple is crushed or gently held in hand.
