MESMER: Towards a Playful Tangible Tool for Non-Verbal Multi-Stakeholder Conversations
- 2020
-
Konferensbidrag (refereegranskat)abstract
- In this paper we present MESMER, a work-in-progress tangible conversation tool for playful design. Our work extends the Otherworld Framework (OF) [7] for tangible tools by centering specifically on play as a conversation topic. Here we unpack how early experiments with OF motivated our work and describe the current iteration of the MESMER tool, which comprises persona cards, various boards, and a shared physical token. MESMER is inspired by our findings from early trials with OF: performative playful interaction promoted playful and divergent thinking; embodied non-verbal communication led to shared insights, the board's contents and structure helped scaffold conversations, a diversity of personas and narratives seemed desirable, and role-playing personas encouraged multi-stakeholder empathy. Our ongoing research aims to help designers and researchers to facilitate engaging, fruitful and inspiring conversations where diverse stakeholders can contribute to playful technology design.

Otherworld: Ouija Board as a Resource for Design

Konferensbidrag (refereegranskat)abstract
- The Ouija board is a device to contact spirits from the so-called otherworld. Although it is considered paranormal activity, the way it works rests on ideomotor actions and we argue that the Ouija is a resource for design for the following aspects: It is a 1) collective tangible exploration tool operated by two or more people through a physical pointer that moves, seemingly on its own, around the letters to probe meanings by composing messages. It has been used by artists as a medium offering 2) creative stimulation to generate material and develop ideas for their work. The Ouija also enables people to express nonconscious knowledge, as research suggests, and thus can provide 3) access to tacit dimension. In this paper, we present the Otherworld Framework that describes its principal elements and provide speculations on how to exploit them in design for collaborative, engaging and unconventional group interactions.

The Spirit of Scientific Communication

Annan publikation (populärvet., debatt m.m.)abstract
- How can I tell what I think till I see what I make and do? — Christopher FraylingJust a couple of months before the start of the new decade and the pandemic began haunting the world, we had the privilege to attend the Halfway to the Future symposium (https://www.halfwaytothefuture.org/2019/) in person and present a paper. The symposium was organized on the occasion of the 20th anniversary of the Mixed Media Lab at the University of Nottingham. There were many exciting keynotes, presentations, and panels. At that time, we did not know that this would be one of the last physical presentations we would give for a while. In this blog post, we would like to talk about the stage performance we did to present our paper and how it motivated us to open a discussion on alternative ways of communicating scientific knowledge, in particular that which is produced through HCI and design research.

- © 2015 Japanese Society of Sleep Research. Sleep disorders constitute an important public health problem. Prevalence of sleep disorders in Turkish adult population was investigated in a nationwide representative sample of 5021 Turkish adults (2598 women and 2423 men, response rate: 91%) by an interviewer-administered questionnaire. Insomnia was defined by the DSM-IV criteria, habitual snoring and risk for sleep-related breathing disorders (SDB) by the Berlin questionnaire, excessive daytime sleepiness (EDS) by the Epworth sleepiness scale score, and restless legs syndrome (RLS) by the complaints according to the International Restless Legs Syndrome Study Group criteria. Mean age of the participants was 40.7 ± 15.1 (range 18 to 90) years. Prevalence rates (men/women) were insomnia 15.3% (10.5%/20.2%; P < 0.001), high probability of SDB 13.7% (11.1%/20.2%; P < 0.001), EDS 5.4% (5.0%/5.7%; P: 0.09), RLS 5.2% (3.0%/7.3%; P < 0.001). Aging and female gender were associated with higher prevalence of sleep disorders except for habitual snoring. Prevalence rates of the sleep disorders among Turkish adults based on the widely used questionnaires were close to the lower end of the previous estimates reported from different parts of the world. These findings would help for the assessment of the health burden of sleep disorders and addressing the risk groups for planning and implementation of health care. Sleep and Biological Rhythms

Thermodynamic Performance Analysis of Hydrofluoroolefins (HFO) Refrigerants in Commercial Air-Conditioning Systems for Sustainable Environment

Tidskriftsartikel (refereegranskat)abstract
- Global warming is one of most severe environmental concerns that our planet is facing today. One of its causes is the previous generation of refrigerants that, upon release, remain in the atmosphere for longer periods and contribute towards global warming. This issue could potentially be solved by replacing the previous generation's high global warming potential (GWP) refrigerants with environmentally friendly refrigerants. This scenario requires an analysis of new refrigerants for a comparison of the thermodynamic properties of the previously used refrigerants. In the present research, a numerical study was conducted to analyze the thermodynamic performance of specifically low GWP hydrofluoroolefens (HFO) refrigerants for an actual vapor compression refrigeration cycle (VCRC) with a constant degree of 3 K superheat. The output parameters included the refrigeration effect, compressor work input, the coefficient of performance (COP), and the volumetric refrigeration capacity (VRC), all of which were calculated by varying the condenser pressure from 6 to 12 bars and vapor pressure from 0.7 to 1.9 bars. Results showed that R1234ze(Z) clearly possessed the desired thermodynamic performance. The drop in refrigeration effect for R1234ze(Z) was merely 14.6% less than that of R134a at a 12 bar condenser pressure; this was minimum drop among candidate refrigerants. The drop in the COP was the minimum for R1234ze(Z)-5.1% less than that of R134a at a 9 bar condenser pressure and 4.7% less than that of R134a at a 1.9 bar evaporator pressure, whereas the COP values of the other refrigerants dropped more drastically at higher condenser pressures. R1234ze(Z) possessed favorable thermodynamic characteristics, with a GWP of 7, and it can serve as an alternative refrigerant for refrigeration systems for a sustainable environment.
