Browsing by offerings on Airbnb means clicking on rows of photos to review options from impending hosts. This kind of table-based navigation is increasingly executive to a digital lives – yet it can be vapid or unfit for people who are blind or have low prophesy to navigate these complicated webpages regulating normal shade readers.
A new proceed grown by engineers during a University of Washington and Carnegie Mellon University uses a keyboard as a two-dimensional approach to entrance tables, maps and nested lists. Results to be presented during the CHI 2018 conference in Montreal find this apparatus lets blind and low-vision users navigate these kinds of sites most some-more successfully than shade readers alone.
“We’re not perplexing to reinstate shade readers, or a things that they do unequivocally well,” pronounced comparison author Jennifer Mankoff, a highbrow in a UW’s Paul G. Allen School of Computer Science. “But tables are one place that it’s probable to do better. This investigate demonstrates that we can use a keyboard to pierce tangible, structured information back, and a advantages are enormous.”
The new tool, Spatial Recognition Interaction Techniques, or SPRITEs, maps opposite collection of a keyboard to areas or functions on a screen. A investigate hearing asked 10 people, 8 of whom were blind and dual with low vision, to finish a array of tasks regulating their favorite shade reader technology, and afterwards regulating that record and SPRITEs. After a 15-minute tutorial, 3 times as many participants were means to finish spatial web-browsing tasks within a given time extent regulating SPRITEs, even yet all were gifted with shade readers.
The apparatus has users press keys to prompt a shade reader to pierce to certain collection of a website. For instance, series keys, along a tip of a keyboard, map to menu buttons. Double-clicking on a series opens that menu item’s submenu, and afterwards a tip quarrel of letters lets a user name any object in a submenu. For tables and maps, a keys on a outward corner of a keyboard act like coordinates that let a user navigate to opposite areas of a two-dimensional feature.
Tapping a series pivotal competence open an idol for any Airbnb menu option, for example. Then drumming a minute “u” could review out a entrance that says possibly this horde will accept pets.
“Rather than carrying to crop linearly by all a options, a apparatus lets people learn a structure of a site and afterwards go right there,” Mankoff said. “You can learn that partial of a keyboard we need to burst right down and check, say, possibly dogs are allowed.”
Most of a exam participants couldn’t finish a charge such as find an object in a submenu or find specific information in a list regulating their favorite shade reader, yet could finish it regulating SPRITEs.
“A lot some-more people were means to know a structure of a webpage if we gave them a pleasing feedback,” pronounced co-author Rushil Khurana, a doctoral tyro during Carnegie Mellon University who conducted a tests in Pittsburgh. “We’re not perplexing to reinstate a shade reader, we’re perplexing to work in and with it.”
For candid text-based tasks such as anticipating a given territory header, counting headings in a page or anticipating a specific word, participants were means to finish them successfully regulating possibly tool.
SPRITEs is one of a apartment of collection that Mankoff’s organisation is building to assistance visually marred users navigate equipment on a two-dimensional screen. An ethnographic study in 2016 led by doctoral tyro Mark Baldwin and expertise member Gillian Hayes, both during a University of California, Irvine, celebrated about a dozen students over 4 months while they schooled to use permitted computing tools, in sequence to find areas for alleviation in shade reading technology.
Now that a group has grown and tested SPRITEs, it skeleton to make a complement some-more strong for any website and afterwards supplement it to WebAnywhere, a free, online shade reader developed during a UW. Adding SPRITEs would let users navigate with their keyboard while regulating a WebAnywhere plugin to review information displayed on a webpage. The group also skeleton to rise a identical technique that would enlarge screen-reading record on mobile devices.
“We wish to muster something that will make a disproportion in people’s lives,” Mankoff said.
