\abstract{This case study intends to examine the feasibility of constructing a \textit{universal} computer workstation, that is suitable for use by individuals of many different body compositions, those factors being; Seated Eye height, Seated Elbow Height, Lap Height, and Popliteal Height. These measurements, better known as  \textit{anthropometric measurements} when inputted into a mathematical statement to then produce a given set of dimensions which, in a mathematical sense would provide the means for a statistically correct workstation. This workstation would thus, work for all individuals that were measured and included in the parsed data.

\section{Background}
\begin{flushleft}
The individuals measured will be labeled our population; they represent the employees who use workstations; their heights vary greatly. Seated height varies between 43ins and 50ins, seated elbow height varies between 24ins and 30ins, lap height varies between 21ins and 27ins, lastly, the popliteal height varies between 15ins and 20ins. Our next measurements are of two existing workstations; a total of 4 measurements had to be taken to ensure everything is accurate. Theses measurements that must be taken are the distance from the top of the monitor to the floor, distance from the keyboard to the floor, distance from the bottom of the desk to the floor, and distance from the floor to where you sit. The measurements are as follows: (INSERT DESK MEASUREMENTS HERE). In order to construct a universal workstation four criteria must be met: seat pan height should be less or equal to the popliteal height, the top of the monitor should be at or below the seated eye height, the keyboard height should be approximately the same height as the elbow height, the desk height should be higher than the lap height. The main goal is to create a universal desk that will accommodate various individuals; the second goal is it must be economical

\section{Analysis}

From the data gathered of the two workstations it may be concluded that neither of them should be used to be reproduced. Some of the areas fit the criteria for instance the Lap height can be shown to be beneficial but when it comes to the average keyboard height it is eliminated across the board for all people. All calculations and comparisons can be shown in the following graph located below:

Developing a solution to this problem is by focusing on the major setbacks of the workstations. Developing a solution to this problem is by focusing on the major setbacks of the workstations which include seated eye height, seated pan height, and the average elbow height. Using these outputs a more desired workstation may be constructed for the customers. Possible solutions for a better designed station would be one that has a lower desk height for the keyboard to sit lower as well to even out with the average elbow height. A lower desk height would also resolve the problem of the eye height being too high up compared to where the top of the monitor sits at for both stations. As for the seat height it seems that having a one dimensional non movemental chair will really be a problem for the fact that the population whom was measured has such varying popliteal height. Staying with the adjustable designed chair that workstation number one offered reigns supreme for the most possible beneficiaries.

\section{Design}
Following up on the design of the desk it was carefully thought through a number of calculations and penalty pieces set into place. First, for using the adjustable chair for the workstation it comes out to be useful for everyone except only person \#6 out of the population. That is benefiting 96\% of the population for the seated pan height While on the other hand chair supremo could cover 100\% of the population depending on a ranging format per inch.
Moving onto the desk design it came down to two solutions thus involved the adjustable desk and desk supremo. The adjustable desk has a height of 25” to 27”. This covers all the lap heights but the only problem is after calculating the monitor height (17.5”) and desk width (2”) it ends up not including three people for seated eye level height which are persons \#4, \#6, and \#25. This isn't entirely bad for the fact that is still good for 88\% of the clientele. As for the the Desk supremo its capabilities can vary depending on any given range. The range we would need though would be 23” to 27”. This is because 23” would cover everyone’s seated eye level height and still be able to be just enough for everyone’s lap height as well. So the outcome would be 100\%. Looking back at the average elbow height it was shown that it was 28.02”, now when configuring that to either of these desks it 100\% applicable for all customers. Due to in part the desk being 2” and the keyboard height sits 1.5” above the table. With the adjustable table it would work for the fact that it goes down to 25” being in the given approximately range of the elbow height. As for the Desk supremo no worries are given at all because it is equipped with an adjustable keyboard shelf.
Now directing to the costs, a chart was designed to show the benefit-cost for both below including the adjustable chair. Take into note that of the three people that it didn't work for the adjustable desk one of them also did not work in with the adjustable chair. This means they are only calculated once for total cost per workstation design. Also they will still have to be included into the Desk supremo/adjustable chair design.
