The Anti-Mac User Interface (Don Gentner and Jakob Nielsen)

To realize the full benefits from the Anti-Mac approach, we argue, it will not be sufficient to retrofit its features one at a time to systems that basically follow current user interface architectures. We believe an integrated design that builds a new user interface from the bottom up will be more coherent and will have a better potential for increasing user productivity by at least an order of magnitude. A full Anti-Mac system will likely have to be based on deep object structures in an architecture that supports network-distributed objects and detailed attributes that are sufficiently

Layered Interaction Analysis of Direct Manipulation (Jakob Nielsen)

As a matter of fact, errors frequently do occur when using direct manipulation systems but in many cases the error messages are pretty poor, maybe because the designers have believed the “no errors” claim. As an example, users of the Macintosh Finder file system interface very often get the error message “An Application could not be found for this Document.” This error message succeeds in breaking almost all the standard principles for message design (Shneiderman 1982b): It uses computer-oriented terminology rather than user-oriented terminology, it is general rather than specific, and it is

Assessing the Usability of a User Interface Standard

After a small section giving recommendations for the process of constructing usable interfaces, the standard defines requirements for menu and command oriented systems. It defines standard function key assignments (F1=help, etc.) and a standard terminology (for example, “personal code” is to be used instead of terms like “userid”). The standard then describes methods to ensure that the user can control and customize the system (e.g., it must be possible to turn audible beeps off). A large part of the standard is devoted to a definition of proper screen design and layout, including the way
