![]() ![]() In both cases, the haptic signals were transmitted via little air pockets on the textile that would inflate to signal a change in direction. The Rice researchers tested out their design in both a wristband and in a long sleeve shirt. “With this work, we were able to create a wearable haptic textile device and reduce much of the bulk that other devices may require because we could embed programming into the fabric itself,” Preston says. Such circuits can be integrated directly into wearable textiles, making the haptic solution less bulky and also more intuitive for the user. To avoid these common pitfalls, Preston and colleagues turned to a technology they call “fluidic programming,” basically fluidic circuits, which use pressure and flow instead of voltage and currents. Four spatiotemporal cues from two sleeves, with each cue actuated by one pressure input. ![]() Two sets of three cells, each, programmed to deliver spatiotemporal cues in opposite directions, were integrated into a sleeve for the forearm. Generally, they’ve relied on external valves and hardware to generate haptic cues, says Barclay Jumet, a Ph.D. Instead of making users watch or listen to directions, the team designed a wearable device that utilizes pneumatic technology to generate small taps on the inside of a wearer’s wrist to silently guide them to their destination.ĭaniel Preston, the assistant professor of mechanical engineering at Rice who led the research, says that part of the reason why haptic devices like this aren’t more widely used is because the technology is typically costly and bulky. And for the more than 2 billion people with partial or total vision or hearing loss, these navigation systems can be nearly useless.Ī team of researchers from Rice University, in Houston, has designed a solution to cut through that noise. Trying to listen to your GPS dictate directions while navigating a busy city or while taking an important work call can be a sensory nightmare.
