Main Effects

An experiment was conducted to study user behavior while entering data in two different locations on a visual display (VDT) screen. Sixteen subjects (eight experienced and eight novice VDT users) performed a data entry task which emphasized screen-keyboard interaction. The entry area was placed either at the top (line 2) or bottom (line 23) of the display, with trials blocked for a given condition. Statistically significant differences were obtained for three anthropometric measures and one time measure on main effects of line location and user experience level. Although significant differences in absolute measures were found, both user groups show the same proportionate improvement when the command line is presented at the bottom, compared with when it is at the top.

The Individual

The American National Standard for Human Factors Engineering of Visual Display Terminal Workstations, the first standard sponsored by the Human Factors Society, is in the final stages of acceptance as an American National Standard. This standard addresses the physical and perceptual aspects of the visual display terminal workstation as used in text processing, data entry, and data inquiry. Standards take on many different forms and fill a variety of needs. Basically a standard provides a reference. Some standards are written so that two systems may be designed to complement each other or fit together. Lightbulbs and fixtures designed to the same standard will work together. In the case of human factors standards one half of the system is already designed, the human. The variety of the design of this part of the system requires that human factors standards identify the parameters to be considered and the corresponding measurement methods needed to insure that the equipment is designed to fit the individual human. A good solution needs to be based on the particular set of circumstances at hand. The voluntary standards method, known as the American National Standards, provides a vehicle for specifying the appropriate parameters and measurement methods while incorporating the necessary flexibility required to insure good designs for individuals. The purpose of this panel session is to provide the society with an interactive session with representatives of the standards drafting committee. A brief history of the committee and its activities will be presented. The panelists will then describe the approach taken in each of the major sections, the mandatory requirements, and the elements the panelists consider to be of particular interest

User Security

As an important part of the new generation of information technology, the Internet of Things (IoT), which is developing rapidly, requires high user security. However, malicious nodes located in an IoT network can influence user security. Abnormal user detection and correlation probability analysis are fundamental and challenging problems. In this paper, the probabilistic model of the correlation between abnormal users (PMCAU) is proposed. First, the concept of user behavior correlation degree is proposed, which is defined as two parts: user attribute similarity degree and behavior interaction degree; the attribute similarity measurement algorithm and behavior correlation measurement algorithm are constructed, respectively, and the spontaneous and interactive behaviors of users were analyzed to determine the abnormal correlated users. Second, first-order logic grammar is used to express the before and after connection of user behavior and to deduce the probabilistic of occurrence of the correlation of behavior and determine the abnormal user groups. Experimental results show that, compared with the traditional anomaly detection algorithm and Markov logic network, this model can identify the users correlated with anomalies, make probabilistic inferences on the possible associations, and identify the potential abnormal user groups, thus achieving higher accuracy and predictability in the IoT.

Main Effects

Spontaneous rhythmical movements, like foot-tapping and head-bobbing, often emerge when people listen to music, promoting the enjoyable sensation of ‘being in the groove’. Here we report the first experiment to investigate if seeing the music maker modulates this experience. Across trials we manipulated groove level in the audio beats (high vs low), and manipulated the match between the audio beats and a concurrently observed point-light display (PLD) of the drummer. The visual display was either fully corresponding with the audio beats, or incompatible across three conditions: a static PLD, a corresponding but asynchronous PLD (0.5s time shifted); or a non-corresponding PLD (e.g. high groove audio paired with low groove PLD). Participants (n = 36) rated: (a) their desire to move; and (b) their perceived groove, purely in response to the audio beats, using 8-point Likert scales. The main effects of groove level and visual display were significant in both measurements. Ratings increased for high compared to low groove audio overall, and for the fully corresponding condition compared to the other visual conditions. Ratings of the desire to move also increased in the static compared to the non-corresponding condition, and the two-way interaction was significant. Desire to move significantly increased for high compared to low groove audio in the fully corresponding, static and asynchronous conditions, while this effect was absent in the non-corresponding condition. These findings identify the importance of seeing as well as hearing the musician for an enhanced experience of groove, which necessitates a multimodal account of music perception.

Body mass index (BMI), electronic media (EM) use, International Physical Activity Questionnaire (IPAQ) scores, selected nutrient intake, smoking, and grade point averages (GPA) were compared between campus recreation (CR) facility users and nonusers at a public, four-year institution in the mid-Atlantic region. Participants (n = 1034) were categorized by CR visits: nonusers, low users (>0 to <1 visit/wk), moderate users (≥1 to <3 visits/wk), or high users (≥3 visits/wk). Significant (p < .05) main effects between user groups were found for BMI, EM use, IPAQ scores, fat intake, smoking, and GPA. High users had better GPA (3.35 vs. ≤3.15 for others), IPAQ scores (8135 MET-min/wk vs. <6800 MET-min/wk for others), and lower fat intake (<30% of total calories vs. >30.9% of total calories for others) than all other groups. High users also had lower BMI (22.8 kg/m2) than moderate users and nonusers (>23.9 kg/m2) and lower EM use (5.56 hr/d) than nonusers (6.55 hr/d). These results indicate that CR visitations are favorably associated with academic achievement and good health.

The Scripting languages (mostly JavaScript) applications in the network are heavily used to improve the user experience now. The trends make XSS (Cross-site Scripting Attacks) the most serious security problems in the current Internet. A XSS defensive scheme based on behavior certification is proposed in the paper. The website behavior model is generated based on the website logic and the user behavior. The browsing behavior certification is implemented based on the expected behavior of the resulting model, so as to offer security for the client even in the case that web server has suffered XSS attacks.

Practical Implications

Purpose The purpose of this paper is to describe the process and implications of usability testing a prototype version of the Letters of 1916 Digital Edition. Design/methodology/approach The paper presents the testing, the lessons learned and how those lessons informed the subsequent redesign of the site. Findings Results imply that a majority of users, even digital humanists, were not looking for a unique and specialised interface, but assumed – and preferred – a user experience that reflects common search systems. Although the audience for digital humanities sites is becoming increasingly diverse, the needs of the different user groups may be more similar than had previously been assumed. Research limitations/implications The usability test employed 11 participants, five of whom were coded as “general public”. Four of these five had previously volunteered to transcribe and upload letters. This meant that they were already familiar with the project and with the Letters of 1916 Transcription Desk. However, their prior involvement was a result of their genuine interest in the site, thus ensuring that their interactions during testing were more realistic. Practical implications The lesson learned may be useful for the Digital Editions of future crowdsourced humanities projects. Originality/value Letters of 1916 is the first crowdsourced humanities project in Ireland. The theme of the project is topical, emotive and socially important in Ireland and among Irish diaspora today. The project’s content has been created by the “ordinary citizens of Ireland” and they are likely to be the major users of the Digital Edition. The study explores how the Digital Edition can support these users, while also facilitating the range of traditional scholars and digital humanities researchers.
