Dead fun: uncomfortable interactions in a virtual reality game for coffins

Uncomfortable interactions are a common aspect of daily life, and have been explored in Human-Computer Interaction; yet little is known about uncomfortable gaming experiences. In this paper, we report on the design and preliminary evaluation of a game in which one player is invited to lie down in a coffin. Results of an exploratory user study suggest that the restricted space of the coffin along with its unsettling cultural connotation led to an engaging, thought provoking experience. By combining the previously separately explored dimensions of physical and psychological discomfort, we hope to better understand the effects that such challenges can have on player experience

Assessment of seating forces imparted through daily activity by children with special needs

Extensor spasms regularly occur in spastic Cerebral Palsy (CP) children making their bodies unbalanced and causing wheelchair instability. Furthermore the child may be uncomfortable as a result of the high contact forces potentially causing pain and injury, which will impair their functional ability. Dynamic seating systems have been designed to absorb the energy associated with these spasms. For people with physical disabilities, especially patients who have strong extensor spasticity, the dynamic design prevents pressure ulcers and injury from impact. However, the quantitative effectiveness and impact of using dynamic components has yet to be established. Therefore our objective is to compare the imparted forces on equivalent rigid and dynamic seating systems, to understand the interactions between force, wheelchair compliance and physical activity throughout a four hour session of non-laboratory based daily living

Effective Interaction: Communicating With And About People With Disabilities In The Workplace

[Excerpt] As children, we are curious —pointing to anything unfamiliar and asking questions. We have few, if any, inhibitions. As adults, we learn to censor our queries, feeling uncomfortable with anything unfamiliar. This is true when we are faced with new technologies. It is true when we are faced with tackling new projects for which we may not feel prepared. It is often true when we meet people who speak a different language or come from a different culture. It is human nature and not unusual, therefore, to be concerned about interactions with people who use wheelchairs, who are blind, who are deaf, or whom we find difficult to understand. We may be concerned that we will say the wrong thing, ask an inappropriate question, or unintentionally offend. We do not want to appear uninformed or insensitive

Implicit Bias Predicts Liking of Ingroup Members Who Are Comfortable With Intergroup Interaction.

We test a novel framework for how ingroup members are perceived during intergroup interaction. Across three experiments, we found that, above and beyond egalitarian attitudes and motivations, White observers' automatic responses to Blacks (i.e., their implicit anti-Black bias) shaped their affiliation toward ingroup targets who appeared comfortable engaging in interracial versus same-race interaction. White observers' implicit anti-Black bias negatively correlated with liking of White targets who were comfortable with Blacks (Experiments 1-3). The relationship between implicit bias and liking varied as a function of targets' nonverbal comfort in interracial interactions (Experiment 1). Specifically, implicit bias negatively correlated with liking of targets when targets' nonverbal behaviors revealed observers felt comfortable with interracial contact, irrespective of the nature of those behaviors (Experiment 2). Finally, the relationship between implicit bias and target liking was mediated by perceived similarity (Experiment 3). Theoretical implications for stigma-by-association, social network homogeneity, and extended contact are discussed

Demographic and psychological variables affecting test subject evaluations of ride quality

Ride-quality experiments similar in objectives, design, and procedure were conducted, one using the U.S. Air Force Total In-Flight Simulator and the other using the Langley Passenger Ride Quality Apparatus to provide the motion environments. Large samples (80 or more per experiment) of test subjects were recruited from the Tidewater Virginia area and asked to rate the comfort (on a 7-point scale) of random aircraft motion typical of that encountered during STOL flights. Test subject characteristics of age, sex, and previous flying history (number of previous airplane flights) were studied in a two by three by three factorial design. Correlations were computed between one dependent measure, the subject's mean comfort rating, and various demographic characteristics, attitudinal variables, and the scores on Spielberger's State-Trait Anxiety Inventory. An effect of sex was found in one of the studies. Males made higher (more uncomfortable) ratings of the ride than females. Age and number of previous flights were not significantly related to comfort ratings. No significant interactions between the variables of age, sex, or previous number of flights were observed

Characterization of whole-body vibration for monorail passenger ride comfort

Train travel has always been a major mode of public transport in developed countries. In the inner cities monorails are often used, which are operated at elevated rail or beam, the main advantage being traffic interactions can be minimized while maintaining its original landscape. Ride comfort is the basic requirement for every passenger in all kind of public transports. In monorail, vibration is considered as major factor of discomfort, it transmitted to human body, which contribute many health issues. The aim of this study was to evaluate the whole-body vibration transmission and the effects to the monorail passengers. There were total of twenty-four experiments conducted in a two-car train monorail on its complete line from Kuala Lumpur Sentral to Titiwangsa stations. Human vibration meter (HVM-100) with tri-axial accelerometer pad was used to measure the WBV of passengers and International Standards Organization (ISO) 2631-1: 1997 was used for analysis. The experimental results show that the daily vibration exposure 0.81 m/s2 was higher than the action value 0.5 m/s2 of the standard during peak operation and 0.82 m/s2 during off-peak operation. The health effect was measured 9.90 m/s1.75 during peak operation and 9.94 m/s1.75 during off-peak operation; both values are observed in moderate health effect zone as per standard (8.5 m/s1.75 to 17 m/s1.75). Moreover, the passenger ride comfort was measured, it was found to be fairly-uncomfortable at rear bogie and not-uncomfortable at center of car. The statistical analysis has proven the significance of orientation, location and operating hours by significant value p = 0.000 (i.e. p < α) with 29.5% of the variance has been accounted between groups. This provides justification to standardization of proper priority seating zone. The findings of this study can assist in the standard specification for seating design of monorail. The statistical analysis shows that all results are statistically significant for orientations, locations as well as operations

Pedestrian Detection with Wearable Cameras for the Blind: A Two-way Perspective

Blind people have limited access to information about their surroundings, which is important for ensuring one's safety, managing social interactions, and identifying approaching pedestrians. With advances in computer vision, wearable cameras can provide equitable access to such information. However, the always-on nature of these assistive technologies poses privacy concerns for parties that may get recorded. We explore this tension from both perspectives, those of sighted passersby and blind users, taking into account camera visibility, in-person versus remote experience, and extracted visual information. We conduct two studies: an online survey with MTurkers (N=206) and an in-person experience study between pairs of blind (N=10) and sighted (N=40) participants, where blind participants wear a working prototype for pedestrian detection and pass by sighted participants. Our results suggest that both of the perspectives of users and bystanders and the several factors mentioned above need to be carefully considered to mitigate potential social tensions.Comment: The 2020 ACM CHI Conference on Human Factors in Computing Systems (CHI 2020

Producing emotionally sensed knowledge? Reflexivity and emotions in researching responses to death

This paper reflects on the methodological complexities of producing emotionally-sensed knowledge about responses to family deaths in urban Senegal. Through engaging in ‘uncomfortable reflexivity’, we critically explore the multiple positionings of the research team comprised of UK, Senegalese and Burkinabé researchers and those of participants in Senegal and interrogate our own cultural assumptions. We explore the emotional labour of the research process from an ethic of care perspective and reflect on how our multiple positionings and emotions influence the production and interpretation of the data, particularly exemplified through our differing responses to diverse meanings of ‘family’ and religious refrains. We show how our approach of ‘uncomfortable reflexivity’ helps to reveal the work of emotions in research, thereby producing ‘emotionally sensed knowledge’ about responses to death and contributing to the cross-cultural study of emotions

Bedside Interactions from the Other Side of the Bedrail

To assess the importance to patients of various aspects of bedside interactions with physician teams. Design : Cross-sectional survey. Setting : VA hospital. Patients : Ninety-seven medical inpatients. Intervention : Survey of 44 questions including short answer, multiple choice, and Likert-type questions. Measurements and Main Results : Data analysis included descriptive statistics. The sample was predominantly male, with a mean age of 62. Overall satisfaction with the hospital experience and with the team of doctors were both high (95% and 96% reported being very or mostly satisfied, respectively). Patients reported learning about several issues during their interactions with the teams; the 3 most highly rated areas were new problems, tests that will be done, and treatments that will be done. Most patients (76%) felt that their teams cared about them very much. Patients were made comfortable when the team showed that they cared, listened, and appeared relaxed (reported by 63%, 57%, and 54%, respectively). Patients were made uncomfortable by the team using language they did not understand (22%) and when several people examined them at once (13%). Many (58%) patients felt personally involved in teaching. The majority of patients liked having medical students and residents involved in their care (69% and 64%, respectively). Conclusions : Patients have much to teach about what is important about interacting with physician teams. Although patients' reactions to team interactions are generally positive, patients are different with respect to what makes them comfortable and uncomfortable. Taking their preferences into account could improve the experience of being in a teaching hospital.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75456/1/j.1525-1497.2005.40192.x.pd
