Product comparison is a common process consumers perform
every day. However, current tools provide limited functions
and poor visual designs. We present ManyLists, a product
comparison tool that compares products’ features using
Spatial Layouts with Animated Transitions. In addition colorcoding
is used to highlight the best features among the products.
A usability study with fourteen participants provided
evidence that the visualization is easy to learn and the animated
transitions are helpful. Finally we propose three guidelines
for Spatial Layouts with Animated Transitions: break
multi-step processes into small comprehensible steps, show
animated transitions for each step, and use spatial layouts to
indicate relationships among features.
