CSUN 2014 talk by Professor Jonathan Hassell describing how Hassell Inclusion, Gamelab UK, and Reflex Arc are using Natural User Interface technologies like Microsoft Kinect to create a whole new generation of assistive technologies based around the movements, gestures and signs different groups of disabled people make.

Two projects are described:
Nepalese Necklace movement games for blind and partially-sighted children that encourage blind and partially-sighted children to engage more readily with their early mobility training through making the body- and spatial-awareness exercises they have to perform the controls for motivational 3D audio-games;

uKinect sign language eLearning games to help people who use sign language to more easily transition into employment by enabling them to learn workplace-specific sign vocabularies using instructive video and our innovative Kinect sign-language recognition system.

1Accessibility and innovation Without these innovators (and more) the lives of disabled people would be much impoverished

Jim Thatcher for the first Screen Reader Thanks to

Ray Kurzweil for the first commercial speech recognition (& much more)

Bill Kastner, WGBH and the BBC for the first closed captioning

Gregg Vanderheiden for starting the accessibility guidelines ball rolling

Tim Berners Lee for “the power of the web is in its universality…” (inspired by Mike Paciello)

The legislators behind Section 508 (USA) and Disability Discrimination Act Pt III (UK)

Rob Sinclair for making ATs easier to create with MSAA and UIA

Maguire & SOCOG for giving the world its first web accessibility test case

The WebAIM crew for getting the word out and stoking the discussion

Julie Howell and the PAS/78 authors for making accessibility more strategic

Shawn Lawton Henry for building a bridge between accessibility & usability

Mick Curran & James Teh for making screenreaders affordable with NVDA

Steve Jobs for making accessibility built in as standard in Apple products

Jennison Asuncion for GAAD And all those who funded their work, used what they created, shared the news… And … As mobile technology enables more people to be innovators

Why shouldn’t your face be here…?

None of those guys were available… so you’ve got me: Jonathan Hassell • >13 years experience in accessibility and inclusion • lead author of BS 8878 British Accessibility Standards • former Head of Usability & Accessibility, BBC • led work to embed accessibility across BBC web, mobile and IPTV production teams • won BIMA 2008 & Access-IT@Home awards for the accessibility features of BBC iPlayer • Product Manager of innovative products: • won IMS Global Learning Impact Award 2010 for MyDisplay • won „Best Usability & Accessibility‟ BIMA 2006 for My Web, My Way • 3 x Bafta-nominated for breakthrough rich-media eLearning projects for disabled children

2What is innovation?

Great innovations come from… User needs Technology possibilities Sustainable market/fundi ng Great innovations

3“Where do you get your ideas from…?” How to source ideas… From following market trends (e.g. everything goes social…) From listening to users‟ unmet needs and finding ways to meet them From encouraging your team to come up with ideas From following technology possibilities (Freeview => Youview) How inclusion helps ideation… From following market trends (e.g. everything goes social…) From listening to users‟ unmet needs and finding ways to meet them From encouraging your team to come up with ideas From following technology possibilities (Freeview => Youview) The problem of fixation… How people try to free themselves from it… ‘Draw an alien’ to free yourself from conventional thinking Why not find a challenge closer to home? Think about how a disabled person would use your product… The beauty of constraints…

© 2011 Centre for Business Innovation Ltd - 34 - Centre for Business Innovation “Connected Communities, helping you Do more with Less” Engineering Design Centre The potential of inclusive design: OXO Good Grips • Well-known pioneer of Inclusive Design in the USA • Sam Farber‟s wife, a keen cook, suffered from arthritis “Why do ordinary kitchen tools hurt your hands?” • First 15 products launched in 1990 • Sales growth over 35% per year from 1991 to 2002 • The line has now grown to over 500 products • Over 100 design awards received Look where asking the right question can get you… How focusing on users takes you beyond inclusion… From following market trends (e.g. everything goes social…) From listening to users‟ unmet needs and finding ways to meet them From encouraging your team to come up with ideas From following technology possibilities (Freeview => Youview) Audience research – focus groups, ethnographic studies etc.

Keep listening through iterative user-testing Do initial audience research User test to get better audience research Develop minimal, flexible next version If more improvement justified, cycle…

How mainstream products have arisen from innovative ‘beyond inclusion’ solutions 4Innovation through Natural User Interfaces

Example 1: uKinect Sign Recognition

Speech recognition is cool

Speech translation is cooler

The Funding Vision • Learners with disabilities may lack independence due to an inability to communicate by speech or due to lack of motor control • If signs and gestures can be easily learned, recognized and converted to digital data, a whole new world of opportunity opens up. TechDis, BIS, TSB SBRI „Making Waves‟ competition

The ideal

The “breakthrough” inspiration • device-to-translate-sign-language-into- speech and events/Fulbright/2012/may/ p

It takes time… – cf. Siri Speech recognition was able to understand digits in the 1950s… Siri‟s intelligence has been worked on for at least 10 years

The problem We had 6 months…

User-focused approach User needs Technology possibilities Sustainable funding/ma rket Great innovations

Our breakthrough technology enabler  The way ahead

The way ahead Looked for people who could benefit from each of our (baby) steps…

Why choose Makaton-users as our target audience? British Sign Language Makaton Thousands of signs (> 21,000) Hundreds of signs Individual sign vocab > 5,000 Individual sign vocab < 200 Long sequences of signs 1 or 2 sign sequences Sign quality fairly uniform Sign quality very variable, plus personal (idiosyncratic) signs Many competing teams innovating in this field Very few competing teams innovating in this field

User-Centred Approach Engagement through a character and humour… Inspiration: Talking Tom

Proof of concept solution Watch the video at:

Phase Two

Users and contexts of use Signing e-Learning game Users with comms difficulties through LDs, Autism, stroke Education Employment Independent Living Supporters of these users: colleagues, teachers, carers, parents

Product launching May-14

Hints of a new opportunity “Boris was so engaging that blind students were also asking to use it to learn to sign…”

Example 2: The Nepalese Necklace A Movement Game for Blind and VI Children

The Nepalese Necklace Original concept • The idea: • using audio-games & Microsoft Kinect‟s gesture recognition to encourage blind and partially-sighted children to engage more readily with their mobility training • The project: • an inexpensive, 3 month Proof of Concept to investigate the idea‟s potential in a concrete, testable way

The Nepalese Necklace UCD Approach • Initial user-research • found experts in the learning, and representatives of the learners • created a way of giving both an initial idea of what we were talking about, to get their attention and buy-in • asked questions to “get into their world” • then created what they needed/wanted • Iterative user-testing • we did this every couple of weeks • there‟s no substitute for it

The Nepalese Necklace Validation • Did final research to prove value • in all contexts of use (in homes as well as as schools) • over longer periods of testing, without expert presence (over at least a week, without you propping the PoC up) • observed and interviewed users & experts to understand how they behave and feel about the PoC • Got the results on video • nothing else quite proves your case

If you remember one thing…

Listening to your diverse audiences needs… identifies challenges… but innovation often follows a challenge
