People in complex scenarios face the challenge of understanding the purpose and effect of other human and computational behaviour on their own goals through intent recognition. They are left asking what caused person or system ‘x’ to do that? The necessity to provide this support human-computer interaction has increased alongside the deployment of autonomous systems that are to some degree unsu...

Calcium is essential for both neurotransmitter release and muscle contraction. Given these important physiological processes, it seems reasonable to assume that hypocalcemia may lead to reduced neuromuscular excitability. Counterintuitively, however, clinical observation has frequently documented hypocalcemia’s role in induction of seizures and general excitability processes such as tetany, Chv...

Wearable fitness trackers have gained a new level of popularity due to their ambient data gathering and analysis. This has signalled a trend toward self-efficacy and increased motivation among users of these devices. For consumers looking to improve their health, fitness trackers offer a way to more readily gain motivation via the personal data-based insights the devices offer. However, the use...

The users of mobile devices increasingly use networked services to address their information needs. Questions asked by mobile users are strongly influenced by contextual factors such as location, conversation and activity. We report on a diary study performed to better understand mobile information needs. Participants’ diary entries are used as a basis for discussing the geographical and situat...

This paper describes an explorative user study of how two different user groups experience current, as well as envisioned new mobile navigation systems. Two groups have been the primary target in this study; a group of elderly people and a group of relatively young university students that were visually impaired. The study consisted of three parts: a focus group/test, a diary study and a design...

JANUARY 2003 AMERICAN METEOROLOGICAL SOCIETY | A s early colonialists crossed the Atlantic Ocean from Europe to North America, they carried preconceived notions on the variation of climate with latitude. Perhaps not surprisingly, they expected to encounter the same climatic conditions at the same latitudes in the New World as they had experienced in the Old World (Kupperman 1982). While the Gul...

HCI research into usability and security over 10 years has repeatedly found that users are unable to cope when faced with unusable password policies. Yet to show the full impact of these policies, it is necessary to consider the context of use within the organisation. Password requirements which users cannot meet have a cost in terms of impact on users’ primary task and, hence, loss of producti...

Information sharing has undeniably become ubiquitous in the Internet age. The global village created on the Internet provides people with instant access to information and news on events occurring in a remote area, including access to video content on websites such as YouTube. Thus, the Internet has helped us overcome barriers to information. However, we cannot conceive an event happening in a ...

This study examined the effects of young athletes’ perceptions of support from coaches and parents on their need satisfaction, motivation, and well-being. Using the framework of selfdetermination theory (Ryan & Deci, 2000b), a 4-week diary study of 33 female gymnasts from the northeastern U.S. was conducted that examined (a) the relations of perceived parent and coach supports to the athlete’s ...

Three daily diary studies were conducted to examine the incidence, nature, and impact of everyday sexism as reported by college women and men. Women experienced about one to two impactful sexist incidents per week, consisting of traditional gender role stereotypes and prejudice, demeaning and degrading comments and behaviors, and sexual objectification. These incidents affected women’s psycholo...
