MoodLight: Exploring Personal and Social Implications of Ambient Display of Biosensor Data

Abstract: MoodLight is an interactive ambient lighting system that responds to biosensor input related to an individual's current level of arousal. Changes in levels of arousal correspond to fluctuations in the color of light provided by the system, altering the immediate environment in ways intimately related to the user's private internal state. We use this intervention to explore personal and social implications of the ambient display of biosensor data. A design probe study conducted with university students provided the opportunity to observe MoodLight being used by individuals and dyads. Discussion of findings highlights key tensions associated with the dialectics of technology-mediated self-awareness and automated disclosure of personal information, addressing issues of agency, skepticism and uncertainty. This study provides greater understanding of the ways in which the representations of personal informatics, with a focus on ambient feedback, influence our perceptions of ourselves and those around us.

Sifteo cubes

Abstract: In this paper we describe Sifteo cubes™, a tangible and graphical user interface platform. We note several patterns of use observed in homes and schools and identify design recommendations for display utilization on distributed interfaces like Sifteo cubes. Additionally we discuss the process of commercializing the research prototype to create a marketable game system.

On the anisotropy of perceived ground extents and the interpretation of walked distance as a measure of perception.

Abstract: Two experiments are reported concerning the perception of ground extent in order to discover whether prior reports of anisotropy between frontal extents and extents in depth were consistent across different measures (visual matching and pantomime walking) and test environments (outdoor environments and virtual environments). In Experiment 1 it was found that depth extents of up to 7 m are indeed perceptually compressed relative to frontal extents in an outdoor environment, and that perceptual matching provided more precise estimates than did pantomime walking. In Experiment 2, similar anisotropies were found using similar tasks in a similar (but virtual) environment. In both experiments pantomime walking measures seemed to additionally compress the range of responses. Experiment 3 supported the hypothesis that range compression in walking measures of perceived distance might be due to proactive interference (memory contamination). It is concluded that walking measures are calibrated for perceived egocentric distance, but that pantomime walking measures may suffer range compression. Depth extents along the ground are perceptually compressed relative to frontal ground extents in a manner consistent with the angular scale expansion hypothesis.

What Happens in Happn: The Warranting Powers of Location History in Online Dating

Abstract: Many location-based dating applications allow users to search for potential matches who are physically proximate. A recent mobile dating application, happn, adds a temporal dimension to location-based dating, showing users the number of times that they crossed path with each other, as well as the location of the most recent overlap. We conducted qualitative interviews with 15 happn users to understand how people make sense of crossed paths, and assess the meanings they assign to these location overlaps. Building on Uncertainty Reduction Theory, we show the various outcomes of the crossed paths and how they play a role in uncertainty reduction. In particular, the warranting power of the device-driven location data was accepted as valuable, and generated little concern about misrepresentation. Moreover, people assigned significant meaning to the minimal cues available from the overlap data. In addition, the location overlap data was useful in allowing users to estimate convenience in meeting and establish common ground. On the other hand, concerns of security and recognition by known others persisted in the happn app. Our findings suggest the potential for utilizing location data outside of the domain of online dating.

You Can't Always Get What You Want: Challenges in P2P Resource Sharing

Abstract: Peer to peer sharing of physical goods in local communities seems like a promising concept, but platforms that offer these services have not yet reached critical mass. Based on a preliminary analysis of 15 interviews with residents of NYC about sharing in the local community, our results suggest that there is a disconnect between the kind of items that people would like to borrow and those that people would be willing to share. While people are most interested in expensive, infrequently used items, they indicated concern over liability for damages and trust of strangers. We discuss the trade-offs of introducing insurance through the platforms themselves and suggest potential alternate ways of facilitating exchanges of these items.

打磨Using Language,倡导新理念

Abstract: 人教版高中英语新课程教材中,语言运用（Using Language）是每个单元必不可少的部分,提供了围绕单元中心话题的听、说、读、写的综合性练习,是单元中心话题的延续和升华.如何设计Using Language部分的教学,使自己的教学模式既不落俗套,又能真正体现新课程标准所倡导的教学理念,正是广大一线英语教师一直努力探索的问题.

Generation Y, web design, and eye tracking

Abstract: Generation Y (age 18-31) is a very large and economically powerful generation, containing eighty-two million people and spending $200 billion annually It is not surprising that companies are interested in gaining the patronage of this group, particularly via the web Surprisingly, very little research into making web pages appealing to this important demographic has been done This paper addresses this need through two separate studies The first, an online survey, provides evidence that our proposed score for predicting the visual appeal of web pages reflects the self report measure of what pages Generation Y likes To refine these findings, an eye tracking study is conducted using the pages that were most and least liked in Study I Participants' eye movement is tracked while browsing these pages, providing evidence of what attracts their attention The results of these two studies suggest that Generation Y may prefer pages that include a main large image, images of celebrities, little text, and a search feature This research has important implications

the impact of a product-harm crisis on marketing effectiveness

Abstract: Product-harm crises are among a firm's worst nightmares. A firm may experience (i) a loss in baseline sales, (ii) a reduced own effectiveness for its marketing instruments, (iii) an increased cross sensitivity to rival firms' marketing-mix activities, and (iv) a decreased cross impact of its marketing-mix instruments on the sales of competing, unaffected brands. We find that this quadruple jeopardy materialized in a case study of an Australian product-harm crisis faced by Kraft peanut butter. We arrive at this conclusion by using a time-varying error-correction model that quantifies the consequences of this crisis on base sales, and on own-and cross-brand short-and long-term effectiveness. The proposed modeling approach allows managers to make more informed decisions on how to regain the brands' pre-crisis performance levels.

EmotionCheck: leveraging bodily signals and false feedback to regulate our emotions

Abstract: In this paper we demonstrate that it is possible to help individuals regulate their emotions with mobile interventions that leverage the way we naturally react to our bodily signals. Previous studies demonstrate that the awareness of our bodily signals, such as our heart rate, directly influences the way we feel. By leveraging these findings we designed a wearable device to regulate user's anxiety by providing a false feedback of a slow heart rate. The results of an experiment with 67 participants show that the device kept the anxiety of the individuals in low levels when compared to the control group and the other conditions. We discuss the implications of our findings and present some promising directions for designing and developing this type of intervention for emotion regulation.
