Bring back the buttons!  HALOS tactile icon stickers help you LOCATE and IDENTIFY every button on your touch surface home appliance.  Tangible Surface Research, LLC will create a custom set of tactile icon stickers for your touch surface appliance.  The stickers are clear so they won't interfere with a sighted person's use of the touchpad controls. And unlike other appliance overlays you don't need to know how to read Braille to use them. Instead of raised dots, these overlays use different shapes to signify what each control does. For example, a raised right-facing triangle shape identifies the Start button on your dishwasher,  a popped kernel shape represents the popcorn button on a microwave 

The custom tactile icon set is part of the Home Appliance Labeling and Overlay System (HALOS) product line. Tangible Surface Research, LLC  also sells individual stick-on shapes that cover specific controls for some appliances.
