Design Objective - Wireless shopping

Explore a product concept to take advantage of the convergence between wireless infrastructure growth and the growth of handheld computing.

Understand/Observe - Wireless shopping

• Identified the behaviors of traditional and online shopping

• Identified the advantages and constraints of handheld computers and wireless infrastructures

Visualize - Wireless shopping

• Worked through concepts using hand drawn paper prototypes

Evaluate/Refine - Wireless shopping

• Used discount usability and design walkthroughs to evaluate the design with classmates

• Conducted usability testing with participants using a PowerPoint simulation to identify issues

• Ran participants through scenarios and measured time to completion and number of errors

• Debriefed the participants with questionairres after the scenarios

• Refined the design based on feedback from testing

Wireless Online Shopping
UW Interface Design Course (2001)

Design Objective:
Explore a product concept to take advantage of the convergence between wireless infrastructure growth and the growth of handheld computing.

Design Solution:
A context-driven shopping interface for a handheld computer. The design takes analogies from traditional shopping and adapts them into the interface. Searching, product comparison, merchant comparison (price and distance), payment, pickup or delivery options, and regular product purchases are all integrated into the interface. Challenges that were identified are contextually searching merchants and products, a non-captive audience, currency, and navigation.

Result:
Completing a small-scale design of a handheld interface for the emerging technologies provides a sense of possible applications for the new shopping medium. The application design identifies possible advantages and disadvantages of wireless online shopping as well as future challenges and conceptual hurdles to product adoption.
