Video help

One effective way to teach a new user about a UI is to make a video tutorial, with a real live person to introduce the purpose of the UI and take the user through the steps involved in using it. Playback of the video could be played during an installation “wizard”, or triggered from a “help” button embedded in the UI itself, or offered as an option at the edge of the screen if the user seems to be hesitating with the next step of an interaction.

The new HbbTV standard for hybrid TV devices makes the task of including video help in applications about as easy as it’s possible to be – by virtue of its support for streaming video over a standard HTTP connection. Perhaps the hardest part will be producing the video in the first place – in a way that looks professional anyway.

What do you think – will video help become a common feature of HbbTV applications?
