The dead lock

Do you think usability and user experience are the same?

Its true that usability or 'ease of use' leads to good user experience but just that doesn't cut it. To achieve good user experience there is still more work left.

Door knobThe door knob shown here is super usable and also follows the first rule of heuristics - visibility of system status. You press a button and the door is locked. To open the door you don't even have to "unlock" it. Just turn the knob and it automatically unlocks and opens the door.

Whats the problem now?

It doesn't "really" make me feel secure. It actually makes me feel stupid and thats bad.

After locking a door by whatever mechanism I usually recheck it by trying to open it again, just to be sure. I'll only be satisfied if the door refuses to open. This lock doesn't allow me to do that. If I try to recheck, the door opens. Once my dad was trying to lock his hotel room door with a similar door knob from inside and he kept on opening it again and again and started complaining that it was not working. In the end I had to give him an assurance that once the button is pushed, no one can open it from outside. He was half convinced even then.

User experience is a combination of many design aspects like info architecture, user interaction, usability and visual design. The right balance of all the them is what creates a good user experience.

Thank you umesh.. Its a good post and I think it wouldve been great if you gave some more examples that re-iterate your thought abt user experience being a balance between many aspects of design :)

@design Retard You dont have to look anywhere else. The iphone is a good example of the marriage of all design aspects http://www.usabilitypost.com/2009/11/03/3-things-phone-manufacturers-should-get-right-to-beat-the-iphone/

I had also written about this shower which looked stunning but was really low in user experience http://whitespace.umeshgopinath.com/2008/04/shower-of-blessings.html

Can you think of a product which looked great but was tough to use

I always test this be keeping the door opened :). I will keep the door opened and lock the knob inside.Then try to open it from outside to make sure that lock works as designed

This is the stupidest of all door locks. I used to live in an apartment where the main door had one of these. I used to get locked out so many times, and only way in was to jump balconies. It was not fun to perform spider man stunts at 4th floor.
