I’m planning to build a smart ring that can detect our body’s motions and brain signals. The device will primarily address a common problem—feeling sleepy during important meetings, lectures, or events. The ring will monitor inactivity in hand gestures over a prolonged period or use other sensors to detect signs of drowsiness. When it senses that the user is feeling sleepy, the ring will deliver a small, harmless electrical impulse to stimulate the part of the brain responsible for alertness, helping the user stay awake and attentive. What do you guys think of this idea?
