Smart clothing controls devices via finger movements – no touching required | The wearer could perform tasks such as turning on appliances, answering phone calls, or operating smart TVs, all just by moving their index finger in the air space above the material.
We've already heard about touch-sensitive clothing that could be used to control devices via touchscreen-like finger taps and swipes on the fabric. The tech sounds impressive, but it does have some limitations. That's where a new "touchless" finger-gesture-detecting fabric comes in.
Well, the general idea is that if the technology were integrated into part of a garment, the wearer could perform tasks such as turning on appliances, answering phone calls, or operating smart TVs, all just by moving their index finger in the air space above the material. By comparing the extent to which the field simultaneously affects the resistance of each sensor, a linked microprocessor is able to determine the real-time three-dimensional position of the finger in the space above the sleeve. By contrast, capacitive textile sensors that actually have to be touched tend to be much more fragile plus they're typically less flexible, making the augmented "smart" clothing more uncomfortable to wear.
