To empower presenters by simplifying setup and presentation in unfamiliar spaces
Designed a user friendly interface for AV system and a simple wireless tabletop podium
Have you ever been confronted with nearly insurmountable audiovisual (AV) compatibility issues as a presenter?
If issues are not solved, many precious hours will be lost, as well as the loss of audience attention and presenter integrity. It is integral to keep this process a smooth one to mitigate these negative effects.

Work and Study Space
We interviewed people from different backgrounds, and also observed presenters who are setting the AV system before and after class. There are lots of pain points when users are using the system. So we drew the pain points into user journey map to show the areas of opportunity revolving around the physical setup and technical aspects of the presentation process.
User Journey Map → Brainstorm → Refine Pain Points to Four Areas → Solutions
Too Many Wires: Wireless Connect
Screen: Embed with Pull Out Option
Podium Size: Largest Laptop Size
Lack of Support: More Intuitive UI
First Iteration Prototypes
The initial podium prototype was built with modularity in mind. Two teammates and I made the prototype through the use of foam-core and velcro to test three features:
screen location, podium dimensions, and angles.
We designed three
sizes and one fixed
height for the

Usability and A/B testing were conducted to allow the team to find additional functional and perception-based improves on the system.
Usability Testing - Users were either allowed to complete a task of their own wanting or giving a task to complete.
A/B Testing - A/B Testing was conducted to determine which screen layouts were preferable and more intuitive.
Needs a phone icon to know when multiroom calling is on or off
Screen Location Test Result
Most prefer to raise screen or integrate screen into lectern top
Some prefer to have screen on right side of lectern base
6 inch length 8-12 inch width is optimal size ranges
Podium Dimension Test Result
Prefer adjustable height
No consensus on top size
Extra spaces is needed
Angle Test Result
Result depends on user’s height
Most prefer no angle
Slight angle (<30 degrees), as long as their laptop won’t be sliding from the table
I and one team
member made the
prototype with an
