Investigating Human Scale Spatial Experience

Spatial experience, or how humans experience a given space, has been a pivotal topic especially in urban-scale environments. On the human scale, HCI researchers have mostly investigated personal meanings or aesthetic and embodied experiences. In this paper, we investigate the human scale as an ensemble of individual spatial features. Through large-scale online questionnaires we first collected a rich set of spatial features that people generally use to characterize their surroundings. Second, we conducted a set of field interviews to develop a more nuanced understanding of the feature identified as most important: perceived safety. Our combined quantitative and qualitative analysis contributes to spatial understanding as a form of context information and presents a timely investigation into the perceived safety of human scale spaces. By connecting our results to the broader scientific literature, we contribute to the field of HCI spatial understanding.

Crowdsroucing of emotional information can take many forms, from social networks data mining to large-scale surveys. The author presents the case-study of emotional mapping in Ostrava´s district Ostrava-Poruba, Czech Republic. Together with the local administration, the author crowdsourced the emotional perceptions of the location from almost 400 citizens, who created 4,051 spatial features. Additional to the spatial data there were 1,244 comments and suggestions for improvements in the district. Furthermore, the author is looking for patterns and hot-spots within the city and if there are any relevant linkages between certain emotions and spatial locations within the city.

The Ideal

Adopting a Lefebvrian perspective that draws attention to the connection between space and power, this study aims to contribute to the organizational literature by offering an in-depth understanding of the processes through which organizational spaces can disable employees with impairments and contribute to the unequal power relations between disabled and non-disabled employees. Based on 65 interviews, it shows how organizational spaces can disable employees with impairments through disabling productivity, social inclusion, independence, and physical comfort and safety. A first contribution this allows this study to make is identifying the different aspects involved in the production of ableist organizational spaces and the way they are connected to the relations of power between disabled and non-disabled employees. It shows how ableist organizational spaces are conceived in an ableist way, become dominated by ableist spatial practice and infuse lived experiences with ableism. Second, this study extends debates on disability in organizations by offering a spatial understanding of ableist notions of the ‘ideal employee’, the reproduction of ableist discourses, and embodied experiences of ableism in organizations. A third contribution this article makes is providing an understanding of the strategies employers and disabled employees use to (attempt to) manage ableist organizational spaces. It argues that as these strategies mainly aim to secure productive participation, they do not address, or can even contribute to, other disabling processes. In this way, they not only reproduce relations of power between employers and disabled employees but also do not fundamentally challenge those between disabled and non-disabled employees.

The Ideal

For a finitely generated group [Formula: see text] acting on a metric space [Formula: see text], Roe defined the warped space [Formula: see text], which one can view as a kind of large scale quotient of [Formula: see text] by the action of [Formula: see text]. In this paper, we generalize this notion to the setting of actions of arbitrary groups on large scale spaces. We then restrict our attention to what we call coarsely discontinuous actions by coarse equivalences and show that for such actions the group [Formula: see text] can be recovered as an appropriately defined automorphism group [Formula: see text] when [Formula: see text] satisfies a large scale connectedness condition. We show that for a coarsely discontinuous action of a countable group [Formula: see text] on a discrete bounded geometry metric space [Formula: see text] there is a relation between the maximal Roe algebras of [Formula: see text] and [Formula: see text], namely that there is a ∗-isomorphism [Formula: see text], where [Formula: see text] is the ideal of compact operators. If [Formula: see text] has Property A and [Formula: see text] is amenable, then [Formula: see text] has Property A, and thus the maximal Roe algebra and full crossed product can be replaced by the usual Roe algebra and reduced crossed product respectively in the above equation.

Insight Into

For inpatients who spend a longer time in the hospital, the built environment plays a significant role in their experience. While many hospital boards aim to create a patient-centered hospital, few have a specific idea about what this means in terms of spatial qualities. This creates a major challenge for those involved in designing hospital environments. Therefore, we aimed to identify which elements play a role in inpatients’ spatial experience, and how these elements relate and interact. Patients were followed during transport and afterward interviewed. In this way, we gained insight into their spatial experience, static, and in motion. This experience turns out to be shaped by material, social, and time-related aspects. An analysis of the interactions between these aspects yields a nuanced understanding of how inpatients’ experience of the hospital environment is shaped by the spatial and social organization, movement, and perspective. This understanding should allow informing hospital boards, architects, and staff to start designing hospital buildings in a more patient-centered way.

Safety Benefit

A field operational test (FOT) is a technique used within traffic safety to evaluate the overall value of in-vehicle information systems (IVISs) under normal operating conditions. In this study, a pan-European FOT was used to evaluate Navigation, Speed Information/Alert, Traffic Information, and Green Driving Support functions together with participants’ perceptions of safety’ before, during, and after using the functions. Through utilization and adherence to the FOT methodology, data were collected over a period ranging from 8 to 16 months in five European countries in order to assess the driver pre-conceived ideas and subsequent subjective and objective experiences with the IVIS functions. Several analyses of data were conducted, and this paper describes the results relating to the ‘user-experience’ as evaluated through subjective responses. The study showed that before the FOTs started, overall participants expected a higher safety benefit through using Speed Alert compared to the other functions. This function was also perceived to offer the highest safety benefit after the FOT had been completed. Perceptions of safety were found to be lowest for the green-driving function. The results offer insights into public expectations of IVIS functions and how these change with experience and overall; they suggest that, in some cases, the perception to safety benefits could be somewhat misplaced.

The Impact

Background Our team previously designed and validated a new bioartificial liver (BAL) called Suppliver based on a Prismaflex™ device, including fluidized bed bioreactors hosting alginate-encapsulated hepatocytes. To ensure correct fluidization within the bioreactor, the beads need to become heavier with the addition of inert glass microspheres. Methods In this study, we assessed the impact of this additional component on the bead production process, bed fluidization, mass transfer and the mechanical properties of the beads, as well as cell viability and basic metabolic function. Results A concentration of 20 mg (1% v/v) of microspheres for 15–20 million cells per milliliter of alginate solution appears to be the best configuration. The filling ratio for the beads in the bioreactors can reach 60%. Four 250-mL bioreactors represent approximately 15% of the hepatocytes in a liver, which is a reasonable target for extracorporeal liver supply. Conclusions Increasing bead density clearly maintained the performances of the fluidized bed with plasma of different compositions, without any risk of release out of the bioreactor. A 1% (v/v)-concentration of microspheres in alginate solution did not result in any alteration of the mechanical or biological behavior. This concentration can thus be applied to the production of large-scale encapsulated biomass for further use of the Suppliver setup in human scale preclinical studies.
