We present the design and evaluation of earPod: an eyes-free menu technique using touch input reactive auditory feedback. Studies comparing earPod with iPod-like visual on reasonably-sized static menus indicate that they are comparable in accuracy. In terms efficiency (speed), is initially slower, but outperforms within 30 minutes practice. Our results potentially a reasonable for general use, particularly exciting use mobile device interfaces.

Background: We propose the use of serious games to screen for abnormal cognitive status in situations where it may be too costly or impractical standard assessments (eg, emergency departments). If validated, health care could enable broader availability efficient and engaging screening. Objective: The objective this work is demonstrate feasibility a game-based assessment delivered on tablet technology clinical sample conduct preliminary validation against mental tools commonly used elderly...

We review HCI history from both the perspective of its 1980s split with human factors and nature as a discipline. then revisit augmentation an alternative to user friendliness that seems particularly relevant in areas inclusive design artificial intelligence. Viewing human-AI interaction kind raises issues such how promote trust situation awareness. also pose question: Can engineering work together solve increasingly urgent challenges technology? In initial look at this question, we contrast...

From the Publisher: Presents a model for intelligent databases based on five information technologies: databases, object-oriented programming, expert systems, hypertext, and text management. This self-contained treatment actually shows how to construct an database microcomputer by building shell much like shells used systems. A realistic example is throughout book illustrate ideas being discussed.

In examining the role of time in mental workload, authors present a different perspective from which to view problem assessment. Mental workload is plotted three dimensions, whose axes represent effective for action, perceived distance desired goal state, level effort required achieve time-constrained goal. This representation allows generation isodynamic contours that incorporate factors operator skill and equifinality effort. An adaptive interface dynamic task reallocation described uses...

Blogging has become the newest communication medium for creating a virtual community, set of blogs linking back and forth to one another's postings, while discussing common topics. In this paper, we examine how communities can be discovered through interconnected as form social hypertext [14]. We propose method model that detects structures community in network by integrating McMillan Chavis' sense [26] along with analysis [8, 11]. From model, measure aligning centrality measures from [17]...

We examine the relationships between contemporary progress in on-road vehicle automation and its coherence with an envisioned "autopia" (automobile utopia) whereby operation task is removed from all direct human control.The progressive of vehicles toward a completely driverless state determined by integration technological advances into private automobile market; improvements transportation infrastructure systems efficiencies; vision future driving as crash-free enterprise. While there are...

The effect of key size on text entry a handheld device while walking and standing was examined in order to answer the following questions: 1) Will additional workload amplify input difficulty? 2) Can speed be used as secondary task measure mental during mobile entry? 13 participants (7 males 6 females) well known sayings (sentences) English into each four conditions, with box ranging width between 2 5 millimetres (mm). Text increased larger up 3mm, faster when (vs. walking). did not depend...

We investigate the use of elastic hierarchies for representing trees, where a single graphical depiction uses hybrid mixture, or interleaving, more basic forms at different nodes tree. In particular, we explore combinations node link and treemap forms, to combine space efficiency treemaps with structural clarity diagrams. A taxonomy is developed characterize design such combinations. software prototype described, which used various techniques visualizing, browsing interacting hierarchies, as...

This chapter reviews relevant research on emotion, focusing aspects of emotion that are most to human factors design. The review begins with a discussion basic concepts, such as low-level positive and negative affect; dimensions arousal valence; prototypical emotions, anger, happiness, fear. interaction between processing cognitive processes, attention, perception, decision making, is also discussed. After the nature problem measuring emotions considered. Available techniques for measurement...

Forest bathing (Shinrin-Yoku in Japanese) is used as an intervention for improving mental health, with VR being to create virtual forests relaxation. Background/Objectives: In this research, we added therapeutic intent a forest the goal of reducing social anxiety, and without instruction. Methods: Fifty-eight first-year psychology students were randomly assigned one three conditions: only, exercises both combined. Results: All conditions enhanced restorative effects equally. However, only...

This paper describes an empathic software agent (ESA) interface using eye movement information to facilitate empathy-relevant reasoning and behavior. Eye tracking is used monitor user's attention interests, personalize the behaviors. The system reacts user in real-time, recording gaze pupil dilation data during learning process. Based on these measures, ESA infers focus of motivational status learner responds accordingly with affective (display emotion) instructional In addition describing...

A three-dimensional model of information exploration is presented. By pointing to three distinct dimensions exploration, we attempt clarify the respective roles human and system in browsing retrieval, characterise alternative interaction styles maximise retrieval effectiveness. We illustrate applicability our by describing eight paradigmatic cases that represent different vertices model. also briefly describe an initial experiment attempted assess pragmatic impact various combinations...

We examine the problem of identifying, measuring and evaluating communities in blogs. In our approach, we use sense community (McMillan Chavis, 1986) centrality measures derived from social network analysis. then describe a method for identifying blogs using both measurement Social Network Analysis (SNA). apply this framework to blog on Canadian independent music. Hypotheses are developed concerning specific structural properties networks formed by blogging relationships how those related...

Gamification and serious games are becoming increasingly important for training, wellness, other applications. How can be developed non-traditional gaming populations such as the elderly, how applied in areas cognitive assessment? The application that we were interested is detection of impairment elderly. Example use cases where gamified assessment might useful are: prediction delirium onset risk emergency departments postoperative hospital wards; evaluation recovery from stroke...
