UBC Evaluation Report -- New Zealand (Expanded Sample)
1999-11-05

Data were collected from 56 surveys completed by braille users in New Zealand, 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 41 % labeling themselves technical users and the remaining 59% 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, 43%, labeled themselves readers. 37% transcribers, 16% teachers, and the remaining 4% labeled themselves proofreaders. The mean number of years the respondents had been using the braille code was 20 years. Additionally, the mean percentage of reading done in braille by respondents was 64%. Almost all of the respondents read braille by touch, with about 40% reading braille by sight. Approximately 23% of the respondents preferred to do all of their reading in braille, while from 10 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 there 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 the UBC features or strategies in question. Among non-technical users, some features received only marginal support, with those favoring the feature not constituting a majority, yet still outnumbering those opposed. These features are: provision of indicators for special type styles such as sans serif, with 48.5% favoring and 30.3% opposing, and dropping EBAE / British Braille contractions which violate UBC rules, with 42.5% favoring and 33.4% opposing. Responses from technical and nontechnical users were fairly similar. Using the chi-squared statistic to test significance, the two groups were found to have significant differences in their responses to only two items: 1) UBC has more symbols than UBAE / British Braille and therefore can more accurately reflect printed text, and 2) UBC Grade I indicators clearly show the boundaries of a Grade I passage in a Grade II text. In both of these instances technical users were significantly less likely to favor the examined strategy or feature. Chi-squared values indicate that we can be 95% confident that these differences in responses between the two groups are so great that they can not be attributable 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 all right 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 7% of respondents felt the new symbols should be struck form the UBC and among non-technical users on average 6.7% of respondents were opposed to the new symbols. Non-technical users were most opposed to the non-directional double quote with 18.2% answering the symbol should be struck from the record, while 21.7% of 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 8%, while the mean percentage of non-technical users in favor of the symbol in a different representation was 2.9%. Technical users were most in favor of changing the representation for the non-directional double quote and the plus sign, with 21.7% favoring a change in each symbol, while non-technical users most favored changing the italicized passage indicator, with 12.1 % favoring a change. 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 significant differences in responses between the two groups only with regards to the changed symbol for the inch sign. Non-technical users were more likely to favor the changed inch sign than technical users. Among those not favoring the symbol, the non-technical users were more likely to desire the changed symbol be removed from the UBC, while technical users were more likely to favor the changed symbol in an altered representation. Majorities of technical and non-technical users were in favor of all of the changed symbols. On the average 13% of technical users and 13.9% 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 garnered the most opposition from technical users with 30.4% opposing the symbol. 21.2% of non-technical users were opposed to the asterisk and the British pound sign. 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 no significant differences in responses between the two groups. However, unlike above, majorities of respondents were not in favor of the symbols examined. On the average technical users were only 33% in favor of the contraction symbol and 56% opposed. Non-technical users had similar results with the average percentage in favor of the contraction symbol 35.2% and the average percentage opposed 53.3%. Users opinions regarding the contracted form of "ble" when followed by a word form the only exception to this pattern with 52.2°îô of technical and 57.6% of non-technical favoring the contraction symbol and 30.4% of technical and 27.3% of non-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, 81 % of respondents were in favor of the new symbols, while 10% were opposed and 5% were in favor of a new symbol in an alternative representation. The symbols for degree sign and non-directional single quote had the weakest support with only 65.2% favoring each of the new symbols. Results of opinions regarding changed symbols were nearly identical to those regarding new symbols, with on the average 71 % approving, 11% opposing, and 5% favoring the changed symbol in a different representation. Summaries of these results may be found in Tables 5 and 6.
