Russ and I went over to the BayCHI event this evening, which included a presentation about running a usability study for mobile services. Here are the five distilled best practices that came out of the data Scott has been collecting:
- Use familiar names as labels for the options. Call the options “Ringtones” or “Downloads”. Using names like “T-Zones” or “Get It Now” just causes confustion.
- Allow purchase from the media list. When the users sees a list of wallpapers they have, there should be an option right there to fine more.
- Link to the download from the web site. People launch the browser to go looking for stuff to download, they should see the option right there. Example given was Verizon, there is no link to the Verizon store from the VZW website.
- Always start the browser on the same page. It seems like people might switch away from the browser and return to their task, but in reality this causes confusion for most users.
- Include previews. Of course people want to see what the image will look like and hear part of the ringtone before they purchase.
