The ISO 9241-9 standard for computer pointing devices proposes an evaluation of performance and comfort [4]. This paper is the first eye tracking evaluation conforming to ISO 9241-9. We evaluated three techniques and compared them with a standard mouse. The evaluation used throughput (in bits/s) as a measurement of user performance in a multi-directional point-select task. The "Eye Tracking Lon...

Kommt intuitive Benutzbarkeit als übergeordnetes Usability-Ziel infrage? Wenn ja, unter welchen Bedingungen? Wie wird geprüft, ob das Ziel erreicht wurde? Nach einer Klärung des Konzepts wird die Frage bearbeitet, inwiefern sich intuitive Benutzbarkeit mit dem UsabilityQualitätsmodell der ISO 9241-Serie vereinbaren lässt. Abschließend werden Implikationen der vorgestellten Überlegungen für den ...

The design and synthesis of porous tungsten oxide (WO3) are challenging issues. tunability oxide's structures properties allows researchers to gain more understanding how different methods, precursors, additives affect its morphology. Read about these topics in the Minireview by P. Bastakoti et al. on page 9241 ff.
