and use databases effectively. <strong>The</strong> AIS system developed at TU Delft is an<br />
example. Testing shows that students use it more effectively than data in<br />
books.<br />
• A reasoning model for designers should be developed to help them go<br />
beyond code requirements. <strong>The</strong> codes and standards should only be guides.<br />
<strong>The</strong> reasoning model could help designers provide an authoritative rationale<br />
for departing from standards (e.g. equivalent facilitation).<br />
• Policy incentives could improve the utilization <strong>of</strong> knowledge. For example,<br />
government purchasing policies could encourage designers to use<br />
anthropometric/ergonomic tools as a means to accommodate a given<br />
percentage <strong>of</strong> the population.<br />
• <strong>The</strong>re needs to be more discussion on the most effective way to present and<br />
collect anthropometric data in a way that will be useful to designers. This is a<br />
major issue <strong>of</strong> concern among researchers. How can we increase demand for<br />
research products One possibility is to make using anthropometric interesting<br />
and entertaining.<br />
Another set <strong>of</strong> recommendations focused on improving data analysis in research to<br />
make use <strong>of</strong> results more effective:<br />
• Data analysis strategies are needed before large-scale surveys are<br />
implemented. Otherwise, the data may not be usable.<br />
• In analysis <strong>of</strong> data, we should not rely on the normal distribution model. We<br />
need to develop new strategies for analysis that take into consideration the<br />
great variation in the population <strong>of</strong> people with disabilities and the fact that<br />
there will be small numbers <strong>of</strong> people in each multidimensional sampling<br />
category.<br />
• Averages are meaningless in design for disabilities. Report findings in<br />
percentiles and also individual performance. This allows users <strong>of</strong> the data to<br />
determine who is being accommodated and, where the aggregated data is<br />
inadequate or not detailed enough, the individual data can be used in<br />
human modeling simulations <strong>of</strong> individuals performing specific tasks.<br />
• Cumulative normal distributions could be more effective than percentiles for<br />
code development because they identify clearly which part <strong>of</strong> the population<br />
is included; however, such an approach implies an assumption <strong>of</strong> normality,<br />
which might not be an accurate way to represent the range <strong>of</strong> body sizes<br />
and abilities <strong>of</strong> those who have disabilities.<br />
• Explore how static anthropometry could be used to predict baseline<br />
functional measures. This would help us adapt static data, which is easier to<br />
collect, for application to functional tasks.<br />
• Develop 3 -D equivalents <strong>of</strong> percentiles in order to make it easy to generate<br />
recommendations for 3 -D data.<br />
