The dyslexia and manual dexterity samples were small n 3 and were not a fully representative sample eg across age and conclusions based on this sample size should be treated with caution Nevertheless they were included to give the research the opportunity to identify major differences or similarities with the blind and partially sighted sample For instance aspects of the design eg scrolling text may cause similar accessibility issues for people with dyslexia Similarly button size shape spacing and press mechanism may affect usability for people with manual dexterity problems as well as for blind and partially sighted people Furthermore DAB radio design features that may cause accessibility difficulties for blind and partially sighted people might also affect usability in a sighted control sample limiting their use of DAB radio functions To ensure that a variety of DAB radio use experiences were identified a range of blind and partially sighted participants with different levels of sight loss were recruited These included participants with congenital and with acquired sight loss All participants from each sub sample were recruited to meet different age band targets see Table 3 1 22 3 Methodology Table 3 1 DAB radio consumer research sampling Sub sample 18 30 years 31 64 years 65 74 Blind partially sighted moderate Blind partially sighted severe A 3 1 2 1 Blind or partially sighted participants Twenty

Bruce McKennell and Walker 1991 Douglas et al 2006 reported that over 90 per cent of blind and partially sighted participants in their Network 1000 research on the opinions and circumstances of visually impaired people in Britain regularly listened to the radio and music Almost half of these participants mentioned without prompting that they regularly listen to radio the remainder mentioned radio on prompting In the same study a high but slightly lower percentage of participants reported regularly watching television 87 per cent As the Network 1000 research reported for participants with sight problems the most popular at home leisure activity was listening to the radio or to music 91 per cent followed by listening to watching television or videos DVDs 87 per cent and reading listening to Talking Books 77 per cent This finding was similar across the wide age range sampled in the Network 1000 study and the popularity of radio was not related to degree of sight loss In their study Bruce McKennell and Walker 1991 reported that over 80 per cent of blind and partially sighted people own and listen to radio and that a further 10 per cent own a radio but do not listen to it In this study they observed an age trend in 15 1 Radio and bind and partially sighted people background that older participants aged 75 were more likely than younger participants to report not owning or listening to the radio 1 2 Ran

28. needs of blind and partially sighted people from digital radio Interestingly some of the interviewees reported that prior to being invited to take part in the interview for the RNIB project they had not thought about whether their products were particularly inaccessible to blind and partially sighted people This finding was supported by an observation that none of the project interviewees companies had conducted their own research on the needs from digital radio equipment of blind and partially sighted consumers Indeed for the majority of participants companies insight on their customers was derived mainly from returns of completed product registration cards The insight provided by such mechanisms tends to be limited It is important to note that this low reporting by participant companies that they conduct user research was observed both in relation to the mainstream non disabled market and to the older and disabled market generally it was not only in relation to blind and partially sighted consumers 10 3 4 Concerns about return on investment Consistent with the findings from interviews with a wider cross section of industry conducted and reported for Ofcom s ACOD to be published in Q4 2008 commercial considerations were those most often raised by industry interviewees Interviewees from the digital radio industry all raised concerns that orienting their organisations to address the needs of blind and partially sighted peopl
29. partially sighted interviewees and respondents to the Short Preference Survey tended to own more radios analogue or digital than did any of the sighted samples Most blind and partially sighted participants across the interviews owned more than one radio and some owned many more indicating potentially larger market sizes than might be assumed solely on the basis of prevalence data for sight loss This observation was supported by data from the Short Preference Survey 87 per cent of the blind and partially sighted sample owned three or more radios DAB or analogue compared with 48 per cent of the nationally representative sample see Figure 5 1 Results table AB5 1 in Appendix B Where specified by respondents to the Short Preference Survey blind and partially sighted respondents owning more than five radios reported owning 7 n 1 9 n 2 10 n 1 12 n 1 15 n 1 more than 20 n 1 and more than 30 n 1 Figure 5 1 How many radios analogue or digital do you have Percentage of sample 100 90 80 70 60 50 40 30 20 j e E m e g 0 EN 5 or more don t know ices of a E nationally representative sample n 225 E blind and partially sighted sample n 100 46 5 Setting the scene The interviewees also revealed that many of their radios were never moved from a particular room and radios were often matched to room d cor have a radio in the living
30. participants who were using a DAB radio without voice output reported needing help from someone else This contrasted significantly with the much lower figure of 39 per cent of the nationally representative sample reporting needing help For subsequent use of DAB radio blind and partially sighted participants using a DAB radio without voice output were again significantly more likely than the nationally representative sample to report needing help 69 per cent versus 17 per cent However a much lower figure namely 48 per cent of blind and partially sighted participants reporting on radios with voice output needed help from someone else at first use and 26 per cent needed help for subsequent use Voice output provided a level playing field as these figures were not significantly different to those for the nationally representative sample However the numbers needing help were significantly higher for those blind and partially sighted participants reporting on use of a DAB radio without voice output Executive summary Comparison of survey responses from blind and partially sighted consumers describing their use of DAB radios with and without voice output clearly demonstrates the high value of voice output for blind and partially sighted consumers More blind and partially sighted users of digital radio with voice output report being able to use their radios independently than do blind and partially sighted users of digital radio without voice o
31. sighted people s interest in advanced functions of DAB radio 7 2 1 Advanced features were not spontaneously associated with DAB radio The majority of participants from the blind and partially sighted sample did not spontaneously cite advanced features such as recording pausing and EPG as being associated with digital radio without the interviewer first suggesting them In most 78 7 Advanced functions cases participants were unaware that DAB radio afforded these extra features When participants were asked about their perceptions and expectations of what digital radio means they typically cited extra stations better quality reception novel stations not available on analogue and ease of use no fiddly tuning 7 2 2 Mixed reaction to advanced features of DAB radio For many people radio is radio unprompted their needs from DAB radio were equivalent to what they have learned to expect from analogue radio to listen to high quality interesting and entertaining programming When advanced features were described to participants reactions varied am not interested in functions like EPC or recording don t think would use them If want to listen to something on radio would listen directly from it understand the recording facility for TV but not very much for radio Pausing or rewinding are not features would use blind and partially sighted mild sight loss male 65 74 years 7 2 2 1 Low

41. B digital radio The project was initiated in recognition that the consumer digital radio equipment market is fast developing and that monitoring the accessibility of digital radio products currently used by blind and partially sighted people might help guide design for easier to use products in the future The key objective of the research project was to gain an in depth understanding of the needs of blind and partially sighted people for consumer digital radio equipment and to establish how these needs differ from those of sighted radio listeners An understanding of these needs is a precursor to improving the accessibility and usability of consumer digital radio equipment A second objective of the research was to understand the extent to which the consumer electronics industry is able and likely to meet these needs The scope of this research is limited to considerations relating to table top and portable digital radio equipment However it has wider relevance because basic user actions are by definition broadly similar for different types of standalone digital radio receiver equipment These actions include switching the device on and off selecting station and changing volume For this reason the equipment needs identified through the current research are applicable to interface design for other stand alone equipment that can receive multi channel digital radio such as stand alone internet radios and radios that belong to the wider digital radi
