Video.Google's Strange Scrollbar Behavior

While on a front-end web contract with a search engine, the UX Designer showed me something strange he came across that he felt broke the UX for Google Videos. I have to say, I totally agree with him.


User Interfaces have standard elements. Some times these visually reflect UI elements of the Operating System, sometimes they reflect UI elements of the User-Agent (browser). When you utilize standard elements, your users will expect them to behave in the learned behavior. When they behave otherwise, you break the user-experience. For less tech savvy users, you may stop them coming back to your service period.

Now the case of the Video.Google Search Scrollbar is not too bad. It does not break the UI, but it does degrade the UX.

Recreate the experience:
  • Go to http://video.google.com
  • Search for a video
  • Click on a video to play it
  • Use the window scroll bar on the right
