UBC Evaluation Report -- Canada
1999-2-15

Data were collected from 40 surveys completed by braille users in Canada, regarding the individuals' use of braille, their opinions regarding suggested changes and additions to the braille code, and opinions regarding the symbols to be changed or added. Data were analyzed with the intention of both identifying trends in opinions regarding various changes in the braille code, and the specific characteristics of the braille users holding these opinions.

The opening portion of the survey asks respondents to describe their braille usage. Respondents identified themselves as either technical or non-technical users of the braille code, with 60% labeling themselves technical users and the remaining 40% non-technical users. Surveys for technical and non-technical users vary slightly, with technical users being asked to complete an additional section regarding symbols for use in the technical code. Respondents also characterized their primary interactions with the braille code as either reading, proofreading, teaching or transcribing. The largest percentage, 50%, labeled themselves transcribers, 27.5% readers, 22.5% teachers, and no one labeled themselves a proofreader. The mean number of years the respondents had been using the braille code was 23. Additionally, the mean percentage of reading done in braille by respondents was 49%. Almost all of the respondents read braille by touch, with about 35% reading braille by sight. Approximately 15% of the respondents preferred to do all of their reading in braille, while from 30 to 50 per cent preferred to read recreational, technical, reference materials, or notes and labels in braille.

Data for technical and non-technical users were analyzed separately to facilitate making comparisons between the two groups. Several statistical techniques were applied. Frequencies of responses to survey items were calculated and the chi-squared statistic was utilized to test for significant differences in responses between the groups. OLS regression coefficients were not calculated, as their were an insufficient number of respondents in each group to produce reliable regression results.

The first 19 items on the survey consist of a series of questions in which the respondent is asked to rate on a scale of one to five, UBC features, such as capitalized passage indicators, or strategies, such as having a unified code for all reading matter. Question 20, regarding quotation mark symbols in UBC, is identical in format but was administered only to technical users. A score of one indicates the respondent felt the feature was completely unacceptable, while a score of two indicates the feature was judged simply unnecessary. A score of three indicates the respondent was neutral toward the feature. A score of four indicates the respondent felt the feature was a good idea, and a score of five indicated the respondent felt the feature was absolutely essential. A majority of respondents favored all of the UBC features or strategies in question, with one exception. Technical users were only 33.3% in favor and 41.7% opposed to the provision of six different quotation marks in the UBC. Additionally, among technical users 21% were opposed to indicators for special type styles such as sans serif type, as well as changing UBC symbols to more accurately reflect printed text. Among non-technical users, 31% were opposed to indicators for special type styles such as sans serif type, as well as following the contracted form of "to" with an intervening space despite the presence of an ambiguous cell. Responses from technical and non-technical users were fairly similar. Using the chi-squared statistic to test significance, the two groups were found to have significant differences in their responses only to the item regarding following the contracted form of "to" with an intervening space. In this instance, non-technical users were significantly less likely to favor the feature. Chi-squared values indicate that we can be 95% confident that these differences in responses between technical and non-technical users are so great that they can not be attributed to random chance or error. A summary of results of questions one through twenty may be found in Table 1.

Item 21 asks respondents to rate new and previously changed UBC symbols, and EBAE or British braille contractions not allowed in UBC, choosing from the following response categories: 1) symbol is acceptable, 2) symbol should be struck from the UBC code, and 3) symbol is alright but the wrong characters have been chosen for its representation. As above, responses from technical and non-technical users were parallel. Responses from technical and non-technical users were not significantly different on any of the items. Among technical users a majority approved of all of the new symbols. Majorities of non-technical users were also in favor of the new symbols. Among technical users on average 6.9% of respondents felt the new symbols should be struck form the UBC, and among non-technical users on average 4.2% of respondents were opposed to the new symbols. Technical users were most opposed to the non-directional double quote with 29.2% answering the symbol should be struck from the record, while 12.5% of non-technical users were opposed to the same symbol. The mean percentage of technical users who were in favor of the new symbols, but in a different representation was 6.5%, while the mean percentage of non-technical users in favor of the symbol in a different representation was 6.6%. However, 25% of both technical and non-technical users favored the times sign when indicated in print by an "x" in a changed representation. A summary of these results may be found in Table 2.

Respondents chose from the same answer categories to rate previously changed symbols. Responses from technical and non-technical users were again parallel, with no significant differences in responses between the two groups. Majorities of technical and non-technical users were in favor of all of the changed symbols. On the average 12.8% of technical users and 12.9% of non-technical users were opposed to any one symbol, feeling the symbols under examination should be struck from the code. The right directional double quote symbol garnered the most opposition from technical users with 29.2% opposing the symbol. 25% of non-technical users were opposed to the right directional double quote and the right directional single quote. A summary of these results may be found in Table 3.

The last section of question 21 asks respondents to use the same answer categories to rate symbols for EBAE and British braille contractions not allowed in UBC. Results for technical and non-technical users were very similar with only one significant difference in response between the two groups. Non-technical users were significantly more likely to oppose the contracted form of "ble" when followed by a word than technical users. Unlike above, majorities of respondents were not in favor of the symbols examined. On the average technical users were only 23% in favor of the contraction symbol and 66% opposed. Non-technical users had similar results with the average percentage in favor of the contraction symbol only 15% and the average percentage opposed 61%. Technical users opinions regarding the contracted form of "ble" when followed by a word form the only exception to this pattern with 67% favoring the contraction symbol, and 12.5% of technical users opposing. Table 4 provides a summary of these results.

Question 22 asked users to rate new and previously changed symbols for use in the technical code. While identical in format to question 21, question 22 was administered only to technical users. Majorities of technical users were in favor of all of the new symbols examined. On the average, 75% of respondents were in favor of the new symbols, while 7% were opposed and 6% were in favor of a new symbol in an alternative representation. The symbols for the end sans serif passage indicator had the weakest support with only 52% favoring the new symbol, and 32% opposing the new symbol. Results of opinions regarding changed symbols were nearly identical to those regarding new symbols, with on the average 81% approving, 5% opposing, and 2% favoring the changed symbol in a different representation. Summaries of these results may be found in Tables 5 and 6.
