Smartphones are such a big part of our daily lives that we pretty much take them for granted. But spare a thought for those who have a disability that makes using a smartphone next to impossible.
This is starting to change thanks to a Wellington start-up staffed entirely by blind people whose aim is to make sure that smartphones are no longer a mission impossible for sight impaired, or blind users.
Using a smartphone when blind or vision impaired can be pretty tricky. For a start there's no bumps or other physical cues to indicate the whereabouts of a button on a smartphone touch screen, which severely limits a smartphone's usefulness to people reliant on touch and sound rather than sight.
Yet there are still many vision impaired or blind people using smartphones. This is largely thanks to screen reading apps such as VoiceOver in iOS, and Talkback in Android.
This hasn't escaped the attention of Appcessible.net founder, Jonathan Mosen, a blind iPhone user who wants to help app developers gain easier access to mobile assistive technologies when creating apps.
"There's apps that cater specifically to the needs of blind people, such as money readers and apps that describe a picture you've taken. But the vast majority of apps we use are designed for a general audience."
