Every year, the Iowa State University's HCI Program sponsors a design challenge for World Usability day.
"As the global economy is facing difficult times financially, we think the promotion of more usable financial systems could assist in creating better decision-making models." (http://www.worldusabilityday.org/)
Pitch a product, service or website that will improve the usability of the world's financial systems. Focus on how your solution solves a specific problem for your target audience and how it will impact society at large.
You may work individually or in teams (up to 5 students) to create a 3-minute pitch video, showcasing your problem, solution and mockups.
Note: The purpose of this challenge is not to create a fully realized solution, but to come up with a user-centered concept that you can communicate through mockups or sketches.
