A friend is blind. The iPhone+voiceover is his primary means of conducting business. We've often talked about UX. Here's what I've learned:
Voiceover is currently an extra layer over a visual interface. So, it amplifies the gesture cost of a visual+touch UI.
After writing a NLP interface for a productivity app, I learned that most of the verbal interaction took less time the visual alternative. It didn't matter if you were sighted or blind. Fitt's law meant that navigating a visual+touch UI was too slow.
So, I'm now working on a verbal+touch UI. In that regard, voiceover users are power users.

- wangii 10y agoInteresting. I have the same conclusion and working on my idea. Which app are you working on?
- mack73 10y agoThe achiles heel for voice-driven UI though is there is no silent mode. Don't you therefor have to create both a GUI and a VUI?
- wangii 10y agoI'm tired of graphics in small screen. I believe millions would agree with me. So no GUI is not a big deal.
- jevinskie 10y agoHmm... perhaps a braille terminal with two-four characters on the bottom of a wrist watch?

- musesum 10y agoYes, I noticed my friend using voiceover in situations that would normally warrant silent operation. White cane allows him some slack. Am attempting a universal product. So, a two part workaround: 1) use voiceover when headphones are connected 2) use tapic engine for clues about marked events This year, pervasive Bluetooth headsets make 1) a lot more viable. Because sighted users may use headsets a bit less, have also included graphic cues. "VUI" - first time I've heard of a VUI. Like it.
- musesum 10y agoI'm developing a productivity app on an Apple WatchOS3, using STT, TTS, and taptic engine. Turns out that applying the same limited interaction area on the iPhone eliminates the need for "reachability". How about you?
- wangii 10y agoWe developed Vorail for bind people. it turns out they really like it. I've finished a prototype on Android to examine the idea of "Sound Virtual Reality". Apart fro the fancy name, it plays multiple streams of audio on different direction (left, front, and right), and allows users to swipe on screens to "move" around.
