The woman’s eyes were closed, her hands during her sides, as she walked quietly toward a wall. Just before creation contact, she jerked to a hindrance – “Oh!” A tiny quivering on her front had warned her of a barrier only a few feet ahead.
Haptic Headband had finished a job.
The device’s creators, Sarah Pinto, Bryce Huerta and Elina Thadhani, presented a wipe during open residence for Haptics: Engineering Touch, an Introductory Seminar for frosh taught by Allison Okamura, a highbrow of automatic engineering. Haptics refers to touch-based interactions, that are executive to most of Okamura’s research.
The group’s plan involves ultrasonic stretch sensors and tiny moving motors mounted on a headband, and some antecedent wiring stored in a waistpack. The idea, a group said, was to assistance blind people navigate their vicinity some-more easily. While Haptic Headband doesn’t nonetheless give users really minute information about what’s around them, “you can feel vast objects entrance toward you,” Thadhani said.
Haptics to assist, haptics to train
Okamura has taught a category twice before, always to students with small or no bearing to robotics or mechanism programming. This year, notwithstanding no pithy instructions to do so, any of a class’s 6 teams grown haptic inclination to support users with special tasks or learn them new skills. “The students are really meddlesome in assistive record and training,” pronounced Okamura, who is also a member of Stanford Bio-X and the Stanford Neurosciences Institute.
In further to Haptic Headband, 3 other teams built assistive haptic devices: a moving glove designed to give a kind of abyss notice to people with blindness, a maritime wristband that vibrates when users are ostensible to spin right or left, and a footbed propitious with vigour sensors that send information to a moving armband.
Charlotte Peale, who designed a feet haptic device with Johnny Armenta and Jabreea Johnson, pronounced that during high propagandize she worked during a podiatry clinic, where she encountered many people with diabetes who had mislaid feeling in their feet. “We wanted to know, what could we do to assistance them with that?” Peale said.
Two other teams designed and built haptic training systems: a picturesque primer rigging change and purchase to assistance sight immature drivers and a haptics-enhanced chronicle of a diversion Operation, finish with forceps that respond to how firmly they’re gripped and shake when players make a mistake, designed to assistance learn new surgeons.
Okamura wanted to learn a march on haptics because, she said, “it has a singular interdisciplinary inlet to it” that touches on engineering, tellurian biology, amicable communication and even ethics. By selecting students with small or no credentials in robotics, she suspicion a category would be generally big and try a far-reaching operation of ideas.
