Blind lead the way in brave new world of tactile technology

Disney’s research hub is developing electrostatic displays, like this jellyfish, that you can actually feel.

Imagine feeling a slimy jellyfish, a prickly cactus or map directions on your iPad mini Retina display, because that’s where tactile technology is headed. But you’ll need more than just an index finger to feel your way around.

New research at UC Berkeley has found that people are better and faster at navigating tactile technology when using both hands and several fingers. Moreover, blind people in the study outmaneuvered their sighted counterparts – especially when using both hands and several fingers – possibly because they’ve developed superior cognitive strategies for finding their way around.

Bottom line: Two hands are better than one in the brave new world of tactile or “haptic” technology, and the visually impaired can lead the way.

”Most sighted people will explore these types of displays with a single finger. But our research shows that this is a bad decision. No matter what the task, people perform better using multiple fingers and hands,” said Valerie Morash, a doctoral student in psychology at UC Berkeley, and lead author of the study just published in the online issue of the journal, Perception.

“We can learn from blind people how to effectively use multiple fingers, and then teach these strategies to sighted individuals who have recently lost vision or are using tactile displays in high-stakes applications like controlling surgical robots,” she added.
