Perceived Usability of Seating in an Outpatient Waiting Area: A Combined Approach Utilizing Virtual Reality and Actual Seating Prototypes

Objective: This study proposed a combined methodology to evaluate the perceived usability of healthcare seats that were first selected in a virtual waiting room which provided the context of use for the seats. Background: There has been an increased interest in using virtual reality (VR) for evaluation of seating in interior environments. Although VR offers a less expensive approach compared to evaluating seats in situ, using VR has limitations as users cannot experience the actual seat prototypes. Method: Participants ( N = 92) experienced a virtual waiting room with various seat groupings and were prompted with four task-based scenarios through which they selected a seat. After the VR phase, they experienced their selected seats in a lab and used an online questionnaire to evaluate the seating. Semi-structured interviews were conducted to garner similarities and differences in participants’ experience of virtual and real seats. Results: Three categories including comfort, support, and flexibility were extracted from the questionnaire. While support and comfort categories were highly ranked by participants, the category rankings varied depending on participants’ age, gender, tasks, and seat types. Interviews revealed that there were differences in experience of the seating materials in VR versus reality, and therefore experiencing the real seats was useful in seating evaluation. Conclusions: The findings suggest that the combined methodology using VR and real seating in a lab is a reliable tool for designers and furniture manufacturers to obtain users’ perceived usability evaluation of seating during the design process while the actual context is absent.

Interior Environments in Long-Term Care Units From the Theory of Supportive Design

Aim: This study was designed to examine how residents in long-term care (LTC) units perceive their living environment based on the theory of supportive design. Background: Healthcare environments may cause a significant level of stress mainly due to patients’ lack of familiarity with such environments and patients’ poor health conditions. According to the theory, the healthcare environments providing a sense of control, social support, and positive distraction can promote wellness. This study was designed to learn how LTC residents perceive their current living environments. Method: This study collected data through qualitative interviews. A total of 48 residents living in two LTC units were asked the three interior environments they liked and they wanted to improve. Only the residents who lived in the current space for 1 month and communicate without any cognitive disabilities were able to participate. Most residents were female and lived in a private room. Results: The participants’ responses indicated the importance of perceived control, social support, and positive distraction in the environment. The most frequently mentioned interior environment that the residents liked was “window and view,” followed by “pictures and photos” and “TV,” while they wanted “bigger room and space,” followed by “improved privacy” and “more options for food.” In addition to the three elements, the participants considered other elements as important for them which can benefit the participants. Conclusion: More studies must be carried out to expand the theory, so that it can be applied to future studies with inclusive perspectives.

Push, Pull, Shrink, Grow: The co-share workplace interior that reflects changing spatial needs

<p>This thesis explores how co-working offices emerged as a solution to the shift in the social expectations of the workplace. It studies how the rise in the number of freelancers and entrepreneurs has resulted in the materialisation of co-working offices. It examines how co-working offices offer flexibility in terms of membership plans, but how their interior environments do not yet reflect this. In short it aims to investigate how these workplace interiors can adapt to meet residents needs. This research embraces the multi-functionality of the co-working office and the demands of residents who occupy these spaces. Three local case studies and international precedents are explored which give insight and offer opportunities on materiality, site context and multi-functional spaces. It explores how to engage residents by challenging how best to design co-working offices. This project considers the requirements of the co-working office and how co-working interiors are occupied throughout the day. The design proposes a kit of parts ‘space making’ solution, which enables co-working offices to meet resident’s needs. This research contributes to the limited published discussion of understanding interior space in the context of co-working offices. This research explores through interior architecture, how co-working offices can be designed to reflect its resident’s individual ways of working and co-workings varying spatial needs. Although based around co-working spaces, the researcher recognises the implications for findings based around corporate office environments.</p>

A Live Interior: Environments, Assemblies, Materialities

This paper examines the interior as a condition that is continuously in production through the arrangement of objects and furniture. This is done along two lines of inquiry. First by examining a few different historical and contemporary conceptions of the domestic interior through the lens of architectural representation. Second by using the technique of laser scanning to document a number of inhabited interiors in two apartment buildings. Through a series of representations, or cloud drawings, produced from the scans, the paper presents three ways of reading the interior: as environments, as assemblies, and as materialities. Departing from Robin Evans’ writing on drawing techniques for representing the interior and their correlation to ways of inhabitation, the paper poses questions around how the understanding of the interior may shift when using emerging techniques for architectural representation. Through readings of Walter Benjamin as well as Sylvia Lavin, the paper discusses such shifts in relation to changes in the conception of the interior and the objects that it contains.

Diverse Proton-Conducting Nanotubes via a Tandem Macrocyclization and Assembly Strategy

Macrocycles that assemble into nanotubes exhibit emergent properties stemming from their low dimensionality, structural regularity, and distinct interior environments. Here, we report a versatile strategy to synthesize diverse nanotube structures in a single, efficient reaction by using a conserved building block bearing a pyridine ring. Imine condensation of a 2,4,6-triphenylpyridine-based diamine with various aromatic dialdehydes yields chemically distinct pentagonal [5+5], hexagonal [3+3], and diamond-shaped [2+2] macrocycles depending on the substitution pattern of the aromatic dialdehyde monomer. Atomic force microscopy and <i>in solvo </i>X-ray diffraction demonstrate that protonation of the macrocycles under the mild conditions used for their synthesis drives assembly into high-aspect ratio nanotubes. Each of the pyridine-containing nanotube assemblies exhibited measurable proton conductivity by electrochemical impedance spectroscopy, with values as high as 10^-3 S m^-1 (90% R.H., 25°C) that we attribute to differences in their internal pore sizes. This synthetic strategy represents a general method to access robust nanotube assemblies from a universal pyridine-containing monomer, which will enable systematic investigations of their emergent properties.

Functional diversity of plant communities at edge and interior of a submontane Atlantic Forest: greater functional than compositional stability

We compared the functional diversity of community at edge and interior areas of an Atlantic forest fragment to test the hypothesis that higher functional diversity exists along edges - in consonance with their higher abundance and floristic diversity as compared to the interior of the forest. By considering a set of vegetative, reproductive and phenological traits and ecosystem service aspects of edge and interior environments, we defined plant functional groups using Cluster Analysis, followed by a silhouette width analysis, together with functional diversity indices of richness, divergence, evenness and dispersion. The main functional groups formed were similar between the edges and interior. Functional richness was the only index that demonstrated differences between edge and the interior. Alterations were perceived in relation to species richness and the Shannon index. Edge effects were not significant in the formation of functional groups. In contrast to our original hypothesis, similar groups were formed both along the edge in the interior - indicating that species played similar ecological roles in both environments, with similar responses to different environmental factors - so that forest edges were colonized by a series of different species that maintained diversity patterns similar to those found in the forest interior.
