It’s important to become aware that appliances now have one of two types of control panel. If possible test any appliance before you buy it because most manufacturers and dealers don’t know how this difference impacts visually impaired users.
Resistive touch flat panel controls are the familiar ones. A resistive touch panel means that the surface resists and you have to press on the right spot to activate the control. Exploring the surface with fingers doesn’t change anything.
The newer capacitive touch controls do not require you to use any pressure to activate the control. A capacitive touch panel senses your finger through electrical differences, and activates wherever your finger touches. No pressure is required! Perhaps you have met this on up-down callbuttons for elevators.
This may work fine for most people but what if you are marking a flat surface control panel with bump dots? You slide your fingers around the touch pad to locate the bumps and each time you touch a cap acitive control you set off a new command. I accidentally put my oven into self-clean mode and the door locked!
People have tried various solutions to use bump markings on capacitive panels: One solution is to cut out a cardboard template so the holes in the template allow only the bump dots to be touched. This makes it less likely that controls will be activated while you explore the panel. My partial solution is to place a couple of bump dots next to the capacitive control panel where the touch setting I want is near the edge. I can find the bump and usually move beyond it to activate the right control. But not all controls are near the edge of the panel!
