When it comes to decide what camera to buy, or any other complex product, within hundreds of other choices, users could use comparison tools to make their decisions. Infographics seem a great way to do that and I am studying their role in creating better user experiences when purchasing online. Do you know of any existing successful website that helps users with infographics to make a decision online?
You can find the product compare feature commonly in ecommerce shops that sell products like computers and phones, where features tend to be a major selling point.
If you consider bar graphs to be infographics then this would be an example.
Infographics aren't a great mechanism for this. They don't allow for easy comparison of complex products. Here are some designs that are good for this:
FitBit's Find Your Fit for wearable devices
- Sorts devices by behavior-centric categories: Everyday, Active, and Performance
- Allows selection of devices in order to compare
- Enables effective comparison through visuals
- Comparison interaction model for devices within lifestyle isn't terribly clear (clicking a device shows its capabilities)
- Photos distract from the comparison
- Different comparison organization for lifestyle and device comparisons (highlighted horizontal list and categories grid with checkboxes, respectively)
Google Compare for credit cards
- Clear explanations of comparison criteria that users may not understand (Intro purchase APR, Regular APR, and Recommended credit score)
- Enables users to quickly scan option set by effectively combining text and imagery
- Detail views are visible with list view
- Granular filtering is more difficult than necessary due to the use of radio buttons rather than checkboxes
Hopefully this is helpful. If not, can you provide a more details as to what you're comparing and a rationale as to why you want to use an infographic? Happy to update my answer.
