Recipe Demo

Hi!

I thought I'd share a little demo I put together using our hand tracking system. One of the advantages of using a touchless interface is it keeps your hands clean from dirty equipment and vice versa. For example, a surgeon who has scrubbed in does not want to handle unsterile equipment such as a computer. Conversely the surgeon does not want to contaminate equipment with the byproducts of surgery. Rather than constantly breaking scrubs or dictating instructions to another person, the surgeon could manipulate images and patient data through a touchless interface. Or imagine someone in waste management who needs to operate a computer or someone in the food industry using a shared computer touched by countless individuals. A touchless interface would keep the equipment and the user's hands clean.

Okay, so maybe you're not a surgeon and you don't work in the dirty jobs industry. But, have you ever cooked while following a recipe on a computer? You probably didn't want to get your food-covered hands all over your nice devices. I've cobbled together a simple demo that allows a budding pastry chef to mark off the steps in a recipe for chocolate chip cookies.

The gestures are simple. The Swipe and Lock gesture crosses off items on the list - with the right hand, the user can perform a pinch in the air and drag to the right to begin crossing off a step in the recipe. Then, rotating the hand clockwise roughly 90 degrees confirms the cross-off. A pinch and drag to the left undos the cross-off. A pinch and drag up or down traverses the steps. The user can also view the ingredients list by using the left hand to perform a double-pinch (like a double-click) and dragging to the right to reveal the second panel.

Check it out:


Following a recipe is a cute example, but there are other applications for checklists such as in a laboratory setting where a scientist might want to cross off steps in a procedure that requires aseptic techniques. Or in the operating room, the doctor might use a checklist as a cognitive aid while performing a procedure.
