Head-mounted displays for virtual environments facilitate an immersive experience that seems more real than an experience provided by a desk-top monitor [18]; however, the cost of head-mounted displays can prohibit their use. An empirical study was conducted investigating differences in spatial knowledge learned for a virtual environment presented in three(More)
Installing security-relevant software updates is one of the best computer protection mechanisms. However, users do not always choose to install updates. Through interviewing non-expert Windows users, we found that users frequently decide not to install future updates, regardless of whether they are important for security, after negative experiences with(More)
When security updates are not installed, or installed slowly, end users are at an increased risk for harm. To improve security, software designers have endeavored to remove the user from the software update loop. However, user involvement in software updates remains necessary; not all updates are wanted, and required reboots can negatively impact users. We(More)
Non-expert computer users regularly need to make security-relevant decisions; however, these decisions tend not to be particularly good or sophisticated. Nevertheless, their choices are not random. Where does the information come from that these non-experts base their decisions upon? We argue that much of this information comes from stories they hear from(More)
Users of social computing websites are both producers and consumers of the information found on the site. This creates a novel problem for web-based software applications: how can website designers induce users to produce information that is useful for others? We study this question by interviewing users of the social bookmarking website del.icio.us. We(More)
People are becoming increasingly reliant on online socio-technical systems that employ algorithmic curation to organize, select and present information. We wanted to understand how individuals make sense of the influence of algorithms, and how awareness of algorithmic curation may impact their interaction with these systems. We investigated user(More)
Video connections can establish a media space in which games may be played, just as people play games while collocated. Experiments with participants playing the game 'Mafia' indicate that people in a video condition have similar levels of satisfaction, fun, and frustration, to those that play while collocated. This finding holds for both those with prior(More)
From email to online banking, passwords are an essential component of modern internet use. Yet, users do not always have good password security practices, leaving their accounts vulnerable to attack. We conducted a study which combines self-report survey responses with measures of actual online behavior gathered from 134 participants over the course of six(More)
