Technology for People with Vision Impairments Canadian Interdisciplinary Vision Rehabilitation Conference – Seminar 3 Julia Foster and Mark Nicol Introductions Mark Nicol, Adaptive Technology Specialist, CNIB ([email protected]; 250-519- 1110) ◦ CNIB, Vancouver Island District ◦ Low Vision Specialist in training ◦ Has had low vision since birth - Congenital Stationary Night Blindness Julia Foster, Occupational Therapist, Inclusive Design Research Centre, OCAD University ([email protected]; 416-977-6000 x3967) ◦ Vision Technology Service (ADP High Tech) ◦ Employment Accommodations Service ◦ SNOW Resource ◦ Co-Chair, Canadian Association of Occupational Therapists (CAOT) Occupational Therapy and Low Vision Rehabilitation Network (OTLVRN) Objectives ◦Identify technologies available for individuals with low vision by applying to client cases (e.g. built-in, third-party, and stand alone devices) ◦Discuss ineffective and effective strategies ◦Hands-on option: try out examples of built-in accessibility settings ◦Q&A: Discuss questions from the audience Find a phone! Feel free to follow along with the demonstrations by doing the same on your own devices ◦ Android users – see if you can find similar features in your phone (likely under Settings > Accessibility) BUT for the speech portions, please either just watch / listen OR use an earbud Human Activity Assistive Technology Model Start with the PERSON doing an ACTIVITY in a CONTEXT, then figure out the best TECHNOLOGY ◦ I.e. fit the tech to the person, not the person to the tech Goal: enabling participation ◦ I.e. more than targeting a simple activity (e.g. reading) ◦ (i.e. how does that activity fit into the day to day life; e.g. tech to support managing a calendar might help a person manage their healthcare appointments or a student manage their assignment due dates) (recreated from Cook & Miller Polgar, 2008) Case 1: Margaret Jenkins ◦78 Year old widow ◦Has ARMD, reads 6M print comfortably without magnifier ◦Son is very supportive but has limited time to devote Case 1: Margaret Jenkins – Technology and Goals Issues/goals Technology ◦ Continue using email, use ◦ Has older Windows PC that is social media, video chat not working for her visually ◦ Discussed pros/cons re: iPad and ◦ Read any necessary hard copy desktop – client chose iPad print - mail, magazines, etc. ◦ Has relied on her son to address issues in the home, ◦ Find cooking ingredients has cut back on use of technology because of vision loss Tablet accessibility features for Margaret ◦ Example: iPad Pro 12.9” Recommended ◦ Pinch zoom where available ◦ Use iOS Zoom for global, variable strength magnification ◦ Turn on bold font, increase contrast, darker colours ◦ Declutter home screen ◦ Plain black home screen ◦ Siri for easy tasks such as timers and alarms ◦ Dictation in place of typing for longer passages ◦ Safari Reader to simplify compatible web pages ◦ VoiceOver Screen Reader to listen to long articles instead of reading visually CCTVs with OCR for Margaret ◦ Example: Optelec Clearview C with Speech (OCR) ◦ Can be used to magnify print, images, 3 dimensional objects such as pill containers. ◦ Provides high contrast settings to increase contrast where it is poor, i.e., news print ◦ Has a full page OCR mode for listening to text Labeling devices for Margaret ◦ Example: PenFriend Audio Labeller ◦ Comes with stickers that can be stuck to magnets, bag clips ◦ Magnets can be attached to cans, bag clips to dry goods ◦ Stickers correspond to audio labels stored in PenFriend ◦ When PenFriend is pointed at the sticker on the magnet attached to a tomatoes, PenFriend will announce “Diced tomatoes” ◦ Food directions can be dictated on to labels “Cook for 40 minutes in oven at 350 degrees celsius” Other potential devices ◦Bank Note Reader ◦Hand magnifier ◦Hand held video magnifier ◦Any others? Case 2: Layla Kouri – Overview ◦ 36 year old lawyer ◦ Supportive manager but competitive workplace ◦ Moderate technology skills ◦ Health history: retinitis pigmentosa with central vision loss; attention deficit hyperactivity disorder (ADHD) Case 2: Layla Kouri – Technology & Goals Technology Issues/goals Work Technology ◦ Read documents when not at ◦ Windows laptop her desk (e.g. handouts in ◦ Magnification software meetings, etc.) ◦ Scanning & reading software ◦ Decrease fatigue and increased ◦ Blackberry efficiency when reading Home Technology ◦ Delay disclosure of her vision ◦ Mac computer and an iPhone loss Smartphone accessibility features for Layla ◦ Read(er) mode – simple article view ◦ VoiceOver – with and without speech ◦ With speech (for vision) ◦ Without speech (for focus) ◦ Headset – for speech ◦ Visual enhancements (minimize changes because not wanting to disclose) ◦ Zoom ◦ Magnifier (like camera but with contrast and colours, Y/B) ◦ Text replacement and word prediction ◦ Siri potentially with scripts to learn commands ◦ Organizational apps OCR Apps for Layla ◦ Low vision specific (i.e. with speech) versus basic OCR ◦ OCR = optical character recognition converts images of typed text into electronic text ◦ Various costs ◦ Some integrated with other products (e.g. Office Lens) ◦ Some integrated with file sharing platforms (e.g. Google Drive, Dropbox) Software features for Layla General and built-in ◦ Keyboard shortcuts! Organization and simplification (e.g. read mode) ◦ Efficiency strategies (e.g. abbreviation expansion a.k.a. auto-correct) ◦ Built-in accessibility for Windows / Microsoft Office (e.g. strategy for Outlook) Magnification software / apps ◦ Focus enhancement + keyboard shortcuts ◦ Visual enhancements Speech ◦ Build in speech step by step – know how to quickly turn on and off ◦ Headset Additional devices/strategies ◦ OCR software + scanner ◦ Electronic documentation ◦ Others? Roadblocks to using technology ◦ Cost of adaptations ◦ Lack of support in learning process ◦ Degenerative conditions require re- adaptation ◦ Breaking old habits (e.g. mouse use) ◦ General web accessibility ◦ Switching learning modes (e.g. visual versus auditory learners) ◦ Stigma/workplace ◦ General discomfort/fear of ◦ New learning to use visual troubleshooting / making changes to environments non-visually technology (“don’t want to break ◦ Case management/enterprise anything”) software Client strategies we’ve seen ◦ Use of hand magnifiers on computer, tablet or smartphone screens ◦ Pushing of computer screen resolution and DPI settings to increase font sizes ◦ Memorization of location and labels of icons, buttons and other controls in apps, programs and operating systems ◦ Hunt and peck typing ◦ Poor posture to get close to desktop or laptop screens ◦ Move pointer into a corner of the screen / shake pointer to find it ◦ Avoiding technology - adopting non-technical means of accomplishing tasks or sometimes just going without Client strategies we’ve seen Memorization of location and labels of icons, Pushing of computer screen resolution and buttons and other controls in apps, programs DPI settings to increase font sizes and operating systems Client strategies we’ve seen Use of hand magnifiers on computer, tablet Move pointer into a corner of the screen / or smartphone screens shake pointer to find it Client strategies we’ve seen – Leaning In Client strategies we’ve seen – no tech! Common Recommendations ◦ Touch typing ◦ Use text-to-speech for long reading ◦ Dictation (note: potential for voice tasks to reduce eye fatigue strain if pre-existing vocal cord ◦ Build skills slowly (e.g. a little bit of issues/overuse) speech at a time) to get buy in ◦ Learning keyboard shortcuts ◦ Focus on client-chosen goals regardless of level of vision loss ◦ Monitor arm ◦ Exploring built-in features independently ◦ Ergonomics/posture ◦ Teaching problem solving ◦ Break down tasks to identify ◦ Control lighting to reduce glare on strategies screens ◦ Others?
