What frustrates me most with computers are examples of poor usability. That is, they are simply difficult to use. The term “usability” has many similar definitions, but really when we are discussing an item’s usability, we are talking about how easily we can learn to use it effectively. Before computers, people could examine the usability of objects. I can imagine two people eating dinner; with one person struggling with their fork. This continues until the person says “You know, it’s much more effective if you use it the other way.” That’s maybe not the best example, after all most people even if they had never seen a fork before would figure out how to use it.Affordance
One reason why people can figure out a fork so easily is that the fork has reasonable good affordance. Simply, it looks like what it should do. It has a handle, is sized easily to fit in your hand, and one end looks good for poking with. Some objects are better than others. Something with wheels you figure you either: ride, push, or pull. It transports something; even if it just itself. 
Some things have poor affordance. If you see something (like the object to the right) and don’t have a clue as to what it does, it has poor (or little) affordance. By the way, it’s a hands-free faucet.
The Computer Connection
Computers brought a host of new usability problems (keyboards, mice, etc.) but where we still struggle is in software and web sites. Software and websites are often digital representations of the real world. So there might be a slider to change a setting, or a button to activate something. In our digital world it is important to have good affordance. A button should just scream that it is ready to be pushed. This is not always the case. Although software has gotten better, it seems as if some web-designers who are trying to be innovative are really destroying a websites usability by making it difficult to navigate.
Frustration Abounds A website that is difficult to navigate makes things painful. It frustrates the user as they try to seek out information. Try visiting the site: http://www.gaia-group.com and find the News and Publications section. This website is a nightmare all because the designer tried to do something different. Examples not as bad are websites with many levels of dropdown menus. In most cases these menus save space at the expense of ease of navigation. There are other sites that are just bizarre and difficult to navigate. I visited the site http://www.crumplerbags.com/ and all I can say is “I guess they sell bags?” I didn’t want to endure the psychotic interface any more than I had to in order to find out more. Cool is important, but usability comes first. What else has bad usability? The interface here to add images to this blog. It wasn’t worth the frustration of trying to place my images where I wanted….I gave up.
