Electronics manufacturers still don’t seem understand how to design easy-to-use controls for their devices. This is particularly true for the thousands of TV/cable box combinations that exist in our homes. While we wait patiently for some specialty company to meet this need, check out this arts-and-crafts modification I found online:
What I don’t understand is why companies don’t simplify their remotes and move to a screen-based menu system. The iPod gets away with only a few buttons and a very basic hierarchy of choices. Seems like a good business niche to me. Of course, you-know-who has already entered the arena with their Apple TV:
This is pretty basic design — almost like it is a working prototype of the cardboard cutout version above. I like this approach because shifts burden of design away from the physical object to the software under the hood. Anybody else?
As I was flipping through the stations on the TV the other day, I became particularly aware of the slight delay between the time I pressed the button on the remote and the actual change of the channel. This is one of those minor annoyances that shouldn’t bother anyone but it just seems weird that all the amazing technological advances in television (high-definition picture, thousands of channels to choose from) should come at the cost of the “crispness” in performance that I remember from the old analog broadcasts.
The lack of responsiveness really becomes noticeable during casual browsing. The two- or three-second pause between channel clicks appears to be much longer than the amount of time the average human needs to evaluate the onscreen content. This sets you up for a lot of waiting and really has a negative impact on the user’s experience. If you have cable, you can use the guide feature, of course, but it just doesn’t provide the same satisfaction as a good, old-fashioned, rapid-fire channel surf.
In a recent article, Jacob Nielsen revisited the topic of website response times and noted that delays of even a few seconds can contribute to an unpleasant user experience. He highlights three basic response speeds and how they relate to the human attention span:
- 0.1 seconds provides a user with the feeling of an instantaneous response — a level of responsiveness that is essential to supporting the feeling of direct manipulation.
- 1 second keeps the user’s flow of thought seamless and still allows them to feel in control. This degree of responsiveness is needed for good navigation.
- 10 seconds keeps the user’s attention but they are starting to feel that they are at the mercy of the computer and wish it was faster. After 10 seconds, their mind starts to wander.
These limits would apply equally well to an established technology like television.
