To be effective, UI agents must be applied to tasks that exploit the potentials of UI agents without expecting them to perform beyond their constraints. The potentials and constraints of two kinds of UI agents (wizards and guides) were consideti and criteria for the application of these UI agents were outlined. An empirical study of 61 0S/2 Warp beta testem with varying degrees of computer experience is ported that assessed respondents' penxptions of the importance, tlequency, and difficulty of 57 information system tasks. Empirical and rational analyses were used to select a set of tasks to which Ul agent technologies were applied in the latest release of IBMs 0S/2 Warp operating system.

This study addresses whether reliable psychology structures underlie differences in the experience of diverse spiritual practices. To address this question, 17 scholars of transpersonal psychology rated the similarity of experiences associated with 10 spiritual practices. A multidimensional analysis revealed a reliable psychological structure underlying the perception of similarities. Qualitative data on the meaning of the identified structure were analyzed for common themes. Results suggest that spiritual practices are experienced as a blend of two underlying dimensions: challenge and mysticism.

This type of project could possibly include gesture recognition, facial recognition, eye tracking, speech recognition, etc. Another non-invasive way to obtain information about a person is through touch. People use their computers to obtain, store and manipulate data using their computer. In order to start creating smart computers, the computer must start gaining information about the user.

Social context may be especially important in mediating the emotional impact of computing activities. In this study, participants completed a questionnaire assessing their perceptions of the similarity of the emotional impact of twenty computing activities. The activities described involved a range of social contexts. A multidimensional scaling analysis revealed two dimensions underlying perceptions of these activities. The two dimensions were interpreted as ranging from “public” to “private” and from “work” to “play.”

Sensors are in the mouse to sense the physiological attributes, which are correlated to emotions using a correlation model. The correlation model is derived from a calibration process in which a baseline attribute-to-emotion correlation is rendered based on statistical analysis of calibration signals generated by users having emotions that are measured or otherwise known at calibration time. A vector in N dimensions, representative of a subject user's emotions, is output for subsequent subject users whose emotions are sought to be known, with the baseline being the reference in the N-dimensional space of the vector.

The device comprises a cartridge and a plurality of analyte detecting members mounted on the cartridge. The cartridge may have a radial disc shape. The cartridge may also be sized to fit within the metering device. The analyte detecting members may be optical system using fluorescence lifetime to determine analyte levels. In one embodiment, the device may also include a fluid spreader positioned over at least a portion of the analyte detecting member to urge fluid toward one of the detecting members. A plurality of analyte detecting members may be used. Each analyte detecting member may be a low volume device.

The system allows the user to indicate the intensity of the emotion to be displayed using a two dimensional plane. Each point on the plane representing a different variation of the direction and intensity of the Control and Affiliation emotions. When the user chooses the point on the plane to represent the emotion, the eyes, eyebrows and mouth of the graphical face are manipulated to represent the indicated emotion.

The assessments collect data on multiple user variables. Multivariate statistical analysis is used to divide the tasks into distinct clusters. The clusters are validated using univariate analysis on each of the measured variables. Intelligent agents are associated based on the measured variables to ensure that agents are effective. The objective assessment and association avoids costly creation and overhead of agents applied where not effective.

In this paper, we examine the effects of employing more "natural" representations in GUIs. In particular, we experimentally assess the impact of object form (2D iconic versus 3D realistic) and layout (regular versus ecological) have on target acquisition time. Results indicate that both form and layout significantly affect performance; subjects located targets more quickly when using interfaces with 3D objects and ecological layouts than they do with 2D objects and regular layouts. An interface with an ecological layout, realistic objects, or both may be an improvement over traditional interfaces.

Experiments I and 2 showed that selfderogations connote submissiveness but are generally judged to be neutral in affiliation. Experiment 3 tested implications for the behavior of dysphoric and nondysphoric Ss as they interacted with a self-derogating, other-derogating, or nonderogating confederate partner. Ss selected a topic from a list and talked about it for 1 rain; the confederates script was fixed. The S's judgments of the confederate, choice of topics, satisfaction with the interaction, and actual responses were analyzed. Self-derogators were judged to be submissive, elicited dominating reactions, and selected more topics with negative content.

Explanations of ignorance and individuals' views of machines as proxies for humans are shown to be inadequate; instead, individuals' responses to technology are shown to be inconsistent with their espoused beliefs. In two laboratory studies, computer-literate college students used computers for tutoring and testing. The first study (N = 22) demonstrates that subjects using a computer that praised itself believed that it was more helpful, contributed more to the subject's test score, and was more responsive than did subjects using a computer that criticized itself, although the tutoring and testing sessions were identical. In the second study (N = 44), the praise or criticism came from either the computer that did the tutoring or a different computer. Subjects responded as if they attributed a "self" and self-focused attributions to the computers (termed "ethopoeia") to the computers. Specifically, subjects responses followed the rules "other-praise is more valid and friendlier than selfpraise," "self-criticism is friendlier than other-criticism," and "criticizers are smarter than praisers" to evaluate the computers, although the subjects claimed to believe that these rules should not be applied to computers.
