QUESTION $3[50$ Points$]$: Podiums are essential in lecture halls because they are comfortable

and provide a formal setting for the teaching process $($or during conferences and other formal

events$).$ However, their size is often fixed or standardized, leading to a lack of accommodation for

the diverse physical status of individuals. Therefore, this one$-$size$-$fits$-$all approach to podium

design often fails to meet the needs of certain users, particularly individuals with disabilities. As a

result, people using these standard$-$height podiums for speeches may experience discomfort, such

as neck and back pain, which can also detract from their concentration and effectiveness while

addressing the audience. Therefore, a study was conducted to determine the most effective

factor$($s$)$ in designing a podium that would yield the highest satisfaction score. The one$-$size$-$fitsall

approach does not suit the varying body sizes of the population, potentially hindering

effectiveness. To address this, the study will identify the most important adjustable features to

design an ergonomic, automated podium to cater to a broader range of body sizes and achieve

higher user satisfaction. To accomplish this objective, having reliable and accurate anthropometric

data becomes essential and helps establish the range of adjustability based on collected data.

Critical measurements for this study include the elbow height while sitting or standing, and surface

inclination $($a total of three factors$).$ These three factors $($and their combinations$)$ were used in an
