Journal ArticleDOI

The influence of design aesthetics in usability testing: effects on user performance and perceived usability.

TL;DR: The results showed that participants using the highly appealing phone rated their appliance as being more usable than participants operating the unappealing model, and the visual appearance of the phone had a positive effect on performance, leading to reduced task completion times for the attractive model.
Journal ArticleDOI

The influence of prototype fidelity and aesthetics of design in usability tests: effects on user behaviour, subjective evaluation and emotion.

TL;DR: The results suggested that task completion time may be overestimated when a computer prototype is being used and users appeared to compensate for deficiencies in aesthetic design by overrating the aesthetic qualities of reduced fidelity prototypes.
Journal ArticleDOI

The influence of age in usability testing.

TL;DR: Age-related differences in the importance of speed and accuracy in task completion point to the need to consider more strongly the factor user age in usability research and practice.
Journal ArticleDOI

The Influence of Product Aesthetics and Usability over the Course of Time: A Longitudinal Field Experiment

TL;DR: It is indicated that product aesthetics influences perceived usability considerably in one-off usability tests but this influence wanes over time, and it is therefore advisable to adopt a longitudinal multiple-session approach to reduce the possibly undesirable influence of aesthetics on usability ratings.
Journal ArticleDOI

Designing automation for complex work environments under different levels of stress.

TL;DR: It emerged that adaptable automation provided advantages over low and intermediate static automation, with regard to mental workload, effort expenditure and diagnostic performance, and a wider range of operational scenarios reflecting adverse as well as ideal working conditions needs to be considered.
