I am working on television EPGs. I was wondering about the maximum permissible delay between a user action and the feedback from Television.

Eg: User presses ChannelUP button on the remote control. TV responds to the action by changing channel. What should be the maximum allowed delay between this for a good user experience?

Jakob Nielsen talks about 3 response times -

I am not sure whether it is applicable for TV watching scenario too.

lease share your knowledge regarding this issue.

Thanks - Nikhil

Hi Nikhil,

while designing a new kind of remote for smart environments incl. TVs, Audio Systems, a dynamic LED Light installation and more, we had to consider the response time of the systems and the remote itself. In our tests/experiments (over 2000 participants) after the deployment of all the systems in a "Smart Home" context we mainly focused on gestures but basically made the same observations as stated by Nielson and the following reports regarding the response times:ยด

Though the last link from IBM is somewhat tied to productivity it shows how these tiny time spans add up (in different places) and thus negatively influence UX as a whole.

Yes sub-second (and even less than 0.6s) response is applicable for a TV/Media scenario.

Hope that helps.

Best Regards
