Building a tabletop podium with a friendly user-interface for presenters

Industrial Design Fundamentals

Type:

Team Work

My Role:

User Research, Prototyping, User Test

THE CHALLENGE

To empower presenters by simplifying setup and presentation in unfamiliar spaces

THE OUTCOME

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.

USE CASES

Non-Video Conference Only Classes

Video Conference Classes

Seminars & Presentations

Work and Study Space

Orientation

Conferences

Workshops

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.
 

IDEATION

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

PROTOTYPING 

First Iteration Prototypes

Podium

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

tabletop podium

___

Users are doing

the task to find

out any issue of

the interface

USER TEST

UI

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

Podium

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

full-scale podium 

prototype with an

origami base
