This paper presents a diary study of rendezvousing as performed by university students. The study suggests that endezvousing frequently does not occur exactly as planned, but this is not necessarily problematic. It also reveals that 'problem' rendezvous were attributed more frequently to modes of travel, over-running of previous activities and lack of(More)
Process models of information seeking are widely held in the Human-Computer Interaction research community. This paper reports a project which applied such models to the design of an intranet resource for the re-use of multimedia training material in the motor industry. The models were found to help identify inherent limitations of an initial prototype, and(More)
This case study explores the effects of written online content on user engagement, and describes the challenges of conducting experiments on live web sites. It compares two versions of a website about bicycle maintenance and repair. One version complied with the guidelines for written online content in "Letting Go of the Words" (Redish, 2007), the other(More)
One strategy for increasing the usefulness, ease of use and satisfaction of wireless navigation and related services is to tailor a package of services to meet the requirements of particular user groups. This paper reports a diary study, which compared the rendezvousing performance and behaviour of two age groups 18-30s and 31-45s. The age groups differed(More)
This paper reports a field evaluation of the mobile phone as a ‘package’ of device and services. The evaluation compares 44 university students’ usage and user experience of communication before and during rendezvous. During a rendezvous, students rated many aspects of the experience of phone use less favourably than before a rendezvous. This impairment of(More)
This paper reports a diary study of rendezvousing as performed by university students. The study compares students’ performance when meeting at familiar and unfamiliar rendezvous points. It reports various findings that help to set goals for the development of personal navigation and related services at appropriate levels. For example, when meeting at novel(More)
This paper reports on a diary study of rendezvousing as performed by university students. The study compares students’ experience of communication before and during rendezvous. During rendezvous, students rated several aspects of the experience of communication lower than before rendezvous. This impairment of experience is attributed to the cumulative(More)
Introduction: As reliance on small unmanned aerial systems (UASs) expands, and sensors requiring higher-bandwidth downlinks are developed, the need for secure high-data-rate communications increases. Laser communication (lasercom), also known as free-space optical (FSO) communication, is inherently low-probability-of-interception and detection (LPI/ LPD).(More)
