Algoriddim, the developers behind the djay line of apps, have opened up a bit about what makes accessibility so important to them. The group's most recent app, djay Pro, recently received an Apple Design Award for, among other things, its usability for visually impaired people.
With VoiceOver enabled, tripleclicking the Home button allows users to tap any button or slider in djay Pro to hear a description of what it does, its state, and how to operate it. For example, tapping the tempo slider will tell by what percentage a song's tempo has been changed, the BPM display will read out its number of beats per minute, and djay Pro will even tell users the key of a song as in "B flat minor". This process allows visually impaired users both navigate and explore the user interface while ensuring they are always hitting the intended button. By double tapping the individual control the user can then perform the original action.
But companies are making accessibility strides in other areas as well, empowering those with disabilities in new and creative ways. Convo, for instance, is a company that has built a video relay system (VRS) for hearing-impaired users, has helped completely change how a deaf-owned and operated business works for the better, not just with dedicated hardware, but software for iPhones, iPads, and Macs.
