Écrire. Près d'un million de dollars pour améliorer techniquement Wikipédia - Histoires numériques. Five Usability Challenges of Web-Based Applications. By Jared M. Spool Originally published: Dec 04, 2007 Back in 2006, networking site Facebook.com introduced a new feature the designers thought users would love. Instead of forcing users to check up on every friend’s Facebook pages constantly to see any change in the friend’s status, they created a “mini feed” which instantly displayed all changes on their own Facebook page. The designers thought users would embrace the new feature, seeing it as a real strength of the site. Instead, users rejected the mini feed. (It’s interesting to note Facebook users found out about the petition by seeing other people sign it in their own mini feed display. Having 10% of your users reject and protest a new feature within 24 hours is an issue unique to web-based applications.
Web-based applications present usability challenges we don’t often see in other types of designs. Usability Challenge #1: Scalability A contributor to Facebook’s mini-feed debacle was the scale of their design. Usability.gov. L'expérience utilisateur chez Google - UX User Experience. The Battle Between Usability and User-Experience - Baekdal.com. The main reasons why it is so hard to create usable products is that there is a conflict between a high-usability level and great user-experience.
You might think this as strange, but there is a important difference between the two. Usability Usability is about the "ability to use" something. The aim for a usable product is to make it easy to use. A product has a high level of usability when: It requires less mental effort to usethe frequency of mistakes using it is less, or when the mistakes are less disastrousit is more powerful, where "more powerful" means that it can be used to do more or do it fasterit is more learnable, that is, when a person can figure it out quicker (source: Rensselaer Polytechnic Institute) Making usable products is thus fairly simple. User-Experience User-experience is not like usability - it is about feelings.
