The experimentation results demonstrate the effectiveness of both SCLO and authoring tool from a pedagogical and usability point of view.
While integration on the user interface level is desirable both from a software engineering as well as from a usability point of view, most current approaches require detailed knowledge of the integrated applications and make the implementation of a common interaction that involves different applications a difficult issue.
From a usability point of view, I just simply don't care about the excuses.
With a terabyte hard drive, broadband connection, and probably about fifty cables snaking out the back, integrating the services is possible, but may be challenging from a usability point of view.
On the other hand, from the usability point of view, the external sensors are out of scope for daily life routines and other systems are overheated by data without reasonable user conclusions or influence.
Cupertino has been roundly mocked for sticking out while the rest of the digital world is shedding pixels and going flat (there's a great dissection of both sides of the flat vs skeuo debate here) but from a usability point of view, flat design can create confusion about which portions of the website or interface are designed to be clicked on, for instance.
In the first version of artifact, a grammar - incorporating personas and Nielsen's heuristics - should be adopted to write the US, where the traditional grammar was modified, by replacing, by replacing (1)
Casual camera users typically prefer the compact size and easy usability of point-and-shoot digital cameras, which have automatic focus and flash options.
Every 10-point increase in the automation score was associated with a usability score 3.8 points higher.
While many of these assays have the advantage of improved sensitivity, such as the ALISSA technique capable of detection of attomolar concentrations, the technology often relies on complex sample processing steps and long incubation times that do not meet usability requirements for point-of-care or point-of-incident diagnostic applications.
