The ability to recognize emotion is one of the hallmarks emotional intelligence, an aspect human intelligence that has been argued be even more important than mathematical and verbal intelligences. This paper proposes machine needs include demonstrates results toward this goal: developing a machine's affective state given four physiological signals. We describe difficult issues unique obtaining reliable data collect large set from subject trying elicit experience each eight states, daily,...

This paper presents methods for collecting and analyzing physiological data during real-world driving tasks to determine a driver's relative stress level. Electrocardiogram, electromyogram, skin conductance, respiration were recorded continuously while drivers followed set route through open roads in the greater Boston area. Data from 24 drives of at least 50-min duration collected analysis. The analyzed two ways. Analysis I used features 5-min intervals rest, highway, city conditions...

Remote measurements of the cardiac pulse can provide comfortable physiological assessment without electrodes.However, attempts so far are non-automated, susceptible to motion artifacts and typically expensive.In this paper, we introduce a new methodology that overcomes these problems.This novel approach be applied color video recordings human face is based on automatic tracking along with blind source separation channels into independent components.Using Bland-Altman correlation analysis,...

We present a simple, low-cost method for measuring multiple physiological parameters using basic webcam. By applying independent component analysis on the color channels in video recordings, we extracted blood volume pulse from facial regions. Heart rate (HR), respiratory rate, and HR variability (HRV, an index cardiac autonomic activity) were subsequently quantified compared to corresponding measurements Food Drug Administration-approved sensors. High degrees of agreement achieved between...

This research investigates the meaning of “human-computer relationship” and presents techniques for constructing, maintaining, evaluating such relationships, based on in social psychology, sociolinguistics, communication other sciences. Contexts which relationships are particularly important described, together with specific benefits (like trust) task outcomes improved learning) known to be associated relationship quality. We especially consider problem designing long-term interaction,...

We describe the Photobook system, which is a set of interactive tools for browsing and searching images image sequences. These differ from those used in standard databases that they make direct use content rather than relying on annotations. Direct search made possible by semantics-preserving compression, reduces to small perceptually-significant coefficients. three particular: one allows based grey-level appearance, uses 2D shape, third textural properties.

There is an interplay, between emotions and learning, but this interaction far more complex than previous theories have articulated. The article proffers a novel model by which to: 1). regard the interplay of upon learning for, 2). larger practical aim crafting computer-based models that will recognize learner's affective state respond appropriately to it, so proceed at optimal pace.

Electrodermal activity (EDA) is a sensitive index of sympathetic nervous system activity. Due to the lack sensors that can be worn comfortably during normal daily and over extensive periods time, research in this area limited laboratory settings or artificial clinical environments. We developed novel, unobtrusive, nonstigmatizing, wrist-worn integrated sensor, present, for very first demonstration long-term, continuous assessment EDA outside setting. evaluated performance our device against...

We show how high-level scene properties can be inferred from classification of low-level image features, specifically for the indoor-outdoor retrieval problem. systematically studied features of: histograms in Ohta color space; multiresolution, simultaneous autoregressive model parameters; and coefficients a shift-invariant DCT. demonstrate that performance is improved by computing on subblocks, classifying these then combining results way reminiscent stacking.

Use of technology often has unpleasant side effects, which may include strong, negative emotional states that arise during interaction with computers. Frustration, confusion, anger, anxiety and similar can affect not only the itself, but also productivity, learning, social relationships, overall well-being. This paper suggests a new solution to this problem: designing human–computer systems actively support users in their ability manage recover from states. An interactive affect–support...

One of the fundamental challenges in pattern recognition is choosing a set features appropriate to class problems. In applications such as database retrieval, it important that image used comparison provide good measures perceptual similarities. We present an model with new address challenge similarity. The based on 2D Wold decomposition homogeneous random fields. three resulting mutually orthogonal subfields have properties which can be described "periodicity," "directionality," and...

The association of irregular sleep schedules with circadian timing and academic performance has not been systematically examined. We studied 61 undergraduates for 30 days using diaries, quantified regularity a novel metric, the index (SRI). In most least regular quintiles, phase light exposure were assessed salivary dim-light melatonin onset (DLMO) wrist-worn photometry, respectively. DLMO occurred later (00:08 ± 1:54 vs. 21:32 1:48; p < 0.003); daily propensity rhythm peaked (06:33 0:19...

In this study, we aim to find physiological or behavioral markers for stress. We collected 5 days of data 18 participants: a wrist sensor (accelerometer and skin conductance), mobile phone usage (call, short message service, location screen on/off) surveys (stress, mood, sleep, tiredness, general health, alcohol caffeinated beverage intake electronics usage). applied correlation analysis statistically significant features associated with stress used machine learning classify whether the...

Wearable computing moves computation from the desktop to user. We are forming a community of networked, wearable-computer users explore, over long period, augmented realities that these systems can provide. By adapting its behavior user's changing environment, body-worn computer assist user more intelligently, consistently, and continuously than system. A text-based reality, Remembrance Agent, is presented illustrate this approach. Video cameras used both warp visual input (mediated reality)...

It much threat to the viability of online networks youth today spam once was email in early days Internet. Current work tackle this problem has involved and psychological studies its prevalence well negative effects While true solutions rest teaching have healthy personal relationships, few considered innovative design network software tool mitigating problem.
