A lire absolument, when to use drag & drop (some informal research results) - issu de tests utilisateurs - pour tout ceux qui utilisent ce mode de manipulation des objets dans des interfaces web.

Based on the results of this testing, the logical findings seem to be that drag and drop is ideal for manipulating the position of objects on a stage, but that when “selecting” objects, simply using click to select is preferable. Even considering that we may be wishing to create an interface that is fun and creative (which was why the full drag and drop approach was originally considered), the inefficiency of this method detracts from the user performing their task. Selecting the objects was considered a preliminary task, and the “fun” part started when users got to manipulating the content.
