2 ©2009 IBM Corporation 2 Agenda  Motivation -Present status of the studies for people with Learning Disabilities (LDs) * -IBM Easy Web Browsing TM (EWB) as a baseline tool  Improvement of “EWB for LDs”  Pilot study -Detail of the study -Results of the interviews  Conclusion  Q&A *As you know, the meaning of LD include not only dyslexia disabilities but math, nonverbal LD and so on. Our team will deal with the problems of LD in the future, though now we treat only the problem of dyslexia. IBM, Easy Web Browsing are trademarks of International Business Machines Corporation in the United States, other countries, or both.

LD: Difficulties in information processing => A potential area where IT could be used Highly affected population LD users have many difficulties in various cognitive areas Governmental policy for developmental disorders in Japan Recent progress in brain science Current Status Little research into the efficacy or sufficiency of existing IT Challenge Identify the potentials of assistive technology (AT) Find out which AT is valuable for them Find out the hidden needs for LDs thorough their opinions => How about enhancements to our existing software for LD users?

4 ©2009 IBM Corporation 4 Easy Web Browsing – a baseline tool What is Easy Web Browsing TM (EWB)? An assistive technology which provides user-friendly operations and accessibility features that enable a variety of end-users to easily access websites. There are various barriers. Difficult to read small font Difficult to read bad color combinations Difficult to read long articles Read aloud at the location pointed at with the mouse Customize the background and text colors Enlarge the indicated text Target Users: senior, Novice IT users, users who have limited vision …

6 ©2009 IBM Corporation 6 Pilot study Pilot study for LD users AimsTo learn what functions are valid To verify the efficacy of this approach Assistive Technology Enhanced EWB for LDs. Enhancements depend on the reading model and the opinions of the LD users. Participants1 st test: 10 people, 2 nd test: 9 people (mostly same users) The study participants were all adults and all Japanese. (Using page is written in Japanese.) Most have LDs, and some have also ADHD. CooperatorsNPO EDGE (Prominent Japanese organization supporting people with LDs) ScheduleAug to Dec. 2008

(*1) Ranking score = [number of top 1] x 8 + [number of top 2] x 4 + [number of top 3] x 2 Each participants were asked to select top 3 functions which they wanted most. RankFunction Do you need it ?

9 ©2009 IBM Corporation 9 1: Read Out Loud Function Summary of the participants’ comment By far the most needed When chosen, this function is almost always selected as the “Best” function. Two main comments for reading out loud - To understand content with a voice because of difficulty in reading characters - To compare the characters on the PC with a voice sound (to learn the words) They have additional requirements. One strong opinion is…. ID Do you need it? AOccasionally BYes C DOccasionally ENo FYes G HOccasionally IYes J 1 Read Out Loud 2 Colored Overlay 3 Line Height

10 ©2009 IBM Corporation 10 A candidate of effective display method - KARAOKE There was a small school near the river. Summary of the participants’ comments Karaoke-like indicator is liked by most users Two main comments on karaoke feature: - Makes it easier to follow the characters with their eyes (similar to tracing a line with their fingers) - Easier to understand the meaning of the sentences. (Easier to combine the words and corresponding sounds.) ID Display method AKaraoke B C D E No need to read aloud F(Other) GKaraoke I J 1 Read Out Loud 2 Colored Overlay 3 Line Height

11 ©2009 IBM Corporation 11 2: Colored Overlay The Stardust spacecraft is on a mission to collect interstellar dust and samples from comets. Summary of the participants’ comment One of the most preferred functions It was significantly more effective than interviewees expectations Two main comments are: 1) Stabilizes how the characters look – irritation decreased with lower contrast 2) Makes words clearer - characters are crisper and sharper and seem to float *Participants A&C choose 2 colors: 1 - Japanese 2 – English IDDo you need it?color A Yes 1:yellow 2:light blue BNo COccasionally1:red 2:light blue D Yes yellow EOccasionallyyellow F Yes yellow G Yes yellow I Yes yellow JOccasionallyyellow 1 Read Out Loud 2 Colored Overlay 3 Line Height

12 ©2009 IBM Corporation 12 3: Line Height Summary of the participants’ comment Easier to follow the sentences with their eyes Reduces confusion with neighboring lines Easier to grasp the shapes of words Easier to see stable word shapes We did not enhance this parameter, but are just reporting selected comments.

The reading out loud function seems to have a positive influence on visual processing and word recognition. Visible? Meaning?

17 ©2009 IBM Corporation 17 Conclusion We improved some of the functions in IBM Easy Web Browsing (EWB), which was developed for people with limited vision and senior citizens, to help LD users. We evaluated the efficacy of the functions. Our conclusions: - ATs are certainly helpful, though their needs vary widely. - The top 3 functions were: 1: Reading out loud, 2: Colored overlays (yellow), and 3: Line height - Their reading speed was better with the ATs The users wanted more flexible customizations and combinations of the ATs.

18 ©2009 IBM Corporation 18 Conclusion To next stage… Why are certain ATs effective? How are brains working? ⁃ The functions still need improvements. ⁃ We want a highly customizable UI programming framework. ⁃ User modeling would support fast and easy individual adaptations.

19 ©2009 IBM Corporation 19 The Most Impressive Comment The ease of access level for Web browsing is directly connected to the quality of life. Therefore this factor influences one's thinking of whether to become pessimistic or optimistic for the inevitable stage of aging. Mail from 6 Sep. 2008

21 ©2009 IBM Corporation 21 Thank You Very Much! contact: 20, Mar, 15:30- 17:00, demonstration of EWB for LD at #270

22 ©2009 IBM Corporation 22 Other functions ruler Underline. It helps to follow the line with their eyes. Magnifi -cation Line space is wider with magnification, but the recognition of the characters becomes difficult. Furigana (Japanese Only) Furigana will help to read however improvements are needed for allocation and coloration. Word separating (Japanese Only) Word separating allows easy word recognition by separating Japanese characters.
