You can perform simple machine operations without directly touching buttons and the like!
When handling food and other items while wearing gloves, there are times when you need to operate machinery. I think it’s a hassle to take off the gloves just to press a button. In such cases, why not try using holographic images to perform simple machine operations? You can just touch the air while still wearing your gloves, so hygiene is not an issue!
