There are three extra facilities in the PROFESSIONAL version, each of which improves accuracy :
 Build
your own User Groups |
|
You can define the users of your design, by combining up to eight of the supplied populations and gender or age groups. You set the proportions, and save them with a suitable name, such as 'people who buy high-end cameras' or according to whatever you are designing.
|
 |
Then PeopleSize always calculates accurate percentiles of that group. This is particularly useful for addressing the issue of who will be using your design - it's unlikely to be 'everyone' or an 'average person', there will nearly always be a bias towards certain ages, gender and income. |
 |
| Fit
the percentage of People that you intend |
|
| PeopleSize Pro has a 'Monte Carlo Modelling' engine, which calculates the proportion of users who will fit a design in several different dimensions at once - because people's proportions vary, every extra dimension that you specify increases the proportion of 'excluded' users. For example, 95th percentile finger breadth excludes 5% of users, then 95th finger length excludes some extra people and so on. In a worst case scenario with 5 different dimensions not much related to each other, setting 5th-to-95th dimensions actually fits only 77% of people altogether. This is a widespread but often unrecognised problem, causing designs to be unwittingly under-specified. |
 |
| Because some dimensions are closely related and tend
to be big or small in the same person, while others vary more, the
calculation is so complicated that only a Monte Carlo Modelling engine
can do it, which is why the problem has been largely ignored
up to now. However it can make a very big difference to how well
a design works in the real world.. You can run the engine in either direction, so if you want a 5th-95th percentile design PeopleSize will tell you the individual Dimension percentiles needed to achieve that, and offer to set them for you. |
|
| Calculate
Connected Dimensions |
|
| This answers the question "AMONG people
who are a certain percentile in Dimension A, what are
(say) the 10th and 90th percentiles in Dimension B?" In this example dialog, it would help to decide about under-desk thigh clearance for worst-case users - those with low seated elbow height who adjust their chair high to have their forearms at desk height. Notice that because elbow height and thigh depth are only loosely related, there is a wide range of thigh depths to be accommodated.
|
 |
| This would guide you towards a desk with a very thin top/frame - gving you a product advantage if you are designing it, or a more comfortable and attentive class, if you are buying them. | |
These are the features in BOTH versions:
| Functionality |
| Output Measurements in mm or inches for the percentile values that you set |
| Calculate Percentile values for Measurements that you have taken |
