Imagining inclusive technological futures through participatory board game design

In 2021, we conducted a series of experimental participatory design workshops that brought diverse groups of participants together to create a board game. The purpose of this project was to use participatory game design as a provocative medium for exploring questions about and ideas for more inclusive and desirable technological futures. This paper presents a report of our experiences conducting this project, reflecting on critical aspects of its creation, facilitation, and outcomes. Through reporting on this reflective practice, we present three key findings that were instrumental in fostering a space for imaginaries of more inclusive and desirable technological futures to emerge. Firstly, through an experimental participatory design structure that promotes polyvocality in the project. Secondly, through applying a critical framework that allowed the game design activities to serve as means for reflecting on social and technological topics. Lastly, by using the affordances of game design to collectively explore ideas for more desirable technological futures. In conclusion, this paper provides methodological insights and possible practical applications of participatory game design for bringing more inclusivity into discussions about, decision-making around, and possibly even the design of future technologies

Exploring adolescents perceptions of the impact of information and communication technologies on parent-adolescent relationships

Magister Psychologiae - MPsychThis study aimed to explore adolescents perceptions of how their use of information and communication technologies may impact on the quality of the parent-adolescent relationship. Obtaining information from adolescents on how they experience their parents interaction with them when they engage with theses technologies, can provide insight into adolescents perceptions of whether information and communication technologies impact on this relationship. This research therefore aimed to explore the way that parents interact with their adolescents on their use of the Internet, gaming activities, or regulating their use of a cell phone, and how this is perceived by adolescents.South Afric

'n Toegepas-linguistiese perspektief op Afrikaanse geletterheidsprogramme in die Suider-Afrikaanse konteks

M.A. (Applied Linguistics)Despite a worldwide drive to eradicate illiteracy, the numbers of illiterates are still soaring. Southern Africa is no exception to this. Even though statistics regarding illiteracy may be misleading, there are an estimated 400 000 illiterate mother tongue speakers of Afrikaans in South Africa. This study tries to establish the reasons for this situation within a historical-political framework. It further provides a sociocognitive basis for mother tongue literacy teaching, relying on the discipline of sociolinguistics. Literacy skills form part of the language user's communicative competence; this study, therefore, endeavours to situate literacy teaching within the communicative approach to language teaching with its emphasis on the needs of the language learner, the functionality of the acquired skills and the active participation of the language learner in the teaching activities. From this perspective a selection of literacy material in Afrikaans, representative of both the mainstream "establishment" type and the more "radical" school, is discussed to arrive at a theoretical and practical rationale for the teaching of literacy to Afrikaans mother tongue speakers, stripped of political undertones which so often direct literacy programmes. The main critique on Afrikaans literacy material is that it is either too behaviouristically structured or that no planned progressive structuring has been built into the courses. Both types of material can lead to dissatisfaction amongst literacy students if the respective course does not fulfil their need for literacy. This situation is often the result of an incomplete needs analysis and the creation of literacy material without a clear image of the target group. The unstructured manner in which literacy material is created and distributed is due to the lack of a national literacy strategy, as well as the nature of adult literacy teaching where specific needs of specific groups of illiterates dictate the type of material. A way of counteracting these problems would be to establish a national organisation to coordinate, amongst others, the development and distribution of literacy material. In this material the needs of the learner will be in a central position with the interaction between the learner and the teacher taking place in meaningful contexts. A thorough knowledge of andragogy and applied linguistics can therefore help to develop literacy material that will benefit Afrikaans illiterates, be they mother tongue speakers of the language or second language users who need to be literate in Afrikaans

Die ontwikkeling van 'n pasklaar-vervaardigde kunsmatige intervertebrale skyf-implantaat

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: Current technology enables researchers to identify a broad spectrum of opportunities in the biomedical industry to develop new and innovative products. Imaging technology, such as Computerised Tomography (CT) scanners or Magnetic Resonance Imaging (MRI) scanners, allow doctors to visualise a patient’s internal organs and bone structure in high quality three-dimensional images. Rapid Prototyping Technology (RPT) can already produce high quality complex parts, such as concept parts for the automobile industry and medical models for preoperative planning. These parts are divided into thin layers and manufactured layer by layer. At the same time the layers are joined together to produce the desired part. Generic artificial intervertebral disc implants already exist. However, these discs are only available in standard geometrical dimensions. The possibility of using imaging technology and RPT to design and manufacture a customized, patient specific implant will be investigated. A simple design (ball and socket) is used to illustrate the design process of a customized disc. It should be noted that this project does not attempt to design a new artificial intervertebral disc implant, but rather describes the design process. The research question is: How accurate can the customised disc implant’s inverse geometry represent the geometry of the vertebrae’s endplates? A preliminary research was done and the results were used to calculate the sample size for this study. A cadaver, provided by Stellenbosch University’s Faculty of Health Sciences’ Anatomy and Histology Department, was CT scanned. The L4- and L5-vertebrae were dissected, cleaned and measured using a photogrammetry measuring machine. Meanwhile, the data gathered from the CT scan is used to design the customised disc implant. The disc is manufactured from Ti6Al4V using a RPT technique called Direct Metal Laser Sintering. After the part is manufactured it is also measured using a photogrammetry measuring machine. The photogrammetry data from the vertebrae and the manufactured customised disc implant are compared, analysed and a hypothesis is formed. It can now be determined, with a certain degree of confidence, how accurate the customised disc implant’s geometry can represent the geometry of the vertebrae’s endplates. The design of a customised disc implant demands many work hours from a qualified engineer or designer, which in turn increases the production costs. This study describes a user-friendly program which will semi-automate the design process. Only limited input from the physician will be required. This program will decrease design time, which will have a direct effect on the production costs. The manufacturing costs are investigated as well. The results from this study indicates that it is possible to design a customized prosthetic, with the help of a custom disc generator, within 27 minutes. The customized disc can then be manufactured with an accuracy of 0.37 mm using rapid prototyping.AFRIKAANSE OPSOMMING: Huidige tegnologie maak dit vir navorsers moontlik om ʼn breë spektrum geleenthede in die biomediese bedryf te identifiseer en nuwe produkte te ontwikkel. ʼn Pasiënt kan met ʼn Gerekenariseerde Tomografie (GT) -flikkergram of ʼn Magnetiese Resonansiebeelding (MRB) - masjien geskandeer word om sodoende ʼn drie-dimensionele beeld van sy of haar interne organe en beenstrukture te verkry. Deur gebruik te maak van snelle prototiperingstegnologie (SPT) kan daar alreeds enige komplekse geometriese vorm vervaardig word. Hierdie tegnologie word ingespan om parte, ontwerp met die hulp van RGO (Rekenaargesteunde Ontwerp), te vervaardig. Die spesifieke part word in dun lae opgedeel en daarna laag vir laag vervaardig. Terselfdertyd word die lae aan mekaar geheg, totdat die gewenste vorm gegenereer is. Die moontlikheid om ʼn GT-flikkergram én SPT te gebruik, met die doel om ʼn pasklaar-vervaardigde, persoon-spesifieke implantaat te ontwerp en te vervaardig, word in hierdie projek ondersoek. Daar bestaan alreeds generiese kunsmatige intervertebrale skyf-implantate (KISI’s). Hierdie skywe word egter beperk deurdat dit slegs in standaard geometriese dimensies vervaardig word. Met dié projek word die moontlikheid van ʼn pasklaar-vervaardigde intervertebrale skyf-implantate (PVKISI) vir ʼn bepaalde pasiënt, ondersoek. ʼn Eenvoudige meganiese ontwerp (bal-en-pootjie) word gebruik om die ontwerpproses van ʼn pasklaar-skyf in hierdie projek te beskryf. Let daarop dat die projek nie poog om ʼn nuwe kunsmatige intervertebrale skyf te ontwerp nie, maar om die ontwerpproses te beskryf. Die vraag wat ondersoek word, is: Hoe akkuraat kan ʼn PVKISI die inverse geometrie van die pasiënt se intervertebrale kontakoppervlaktes voorstel? ʼn Voorafgaande ondersoek is gedoen en die resultate is gebruik om die steekproef-grootte vir hierdie studie te bepaal. ʼn Kadawer, voorsien deur die Universiteit van Stellenbosch se Fakulteit Gesondheidwetenskappe se Departement Anatomie en Histologie, is met ʼn GT-flikkergram geskandeer. Die L4- en L5-werwels is gedissekteer, skoon gemaak en met ʼn fotogrammetriemeetmasjien gemeet. Intussen is die data, verkry van die GT-flikkergram, gebruik om die PVKISI te ontwerp. Die PVKISI is van Ti6Al4V vervaardig deur Direkte Metaal Laser-Sintering (DMLS). Die part is ook met ʼn fotogrammetrie-meetmasjien gemeet. Die fotogrammetrie-data van die werwels en die PVKISI is vergelyk, geanaliseer en ʼn hipotese is daar gestel. Daar kan dus met statistiese sekerheid bepaal word hoe akkuraat die PVKISI die inverse geometrie van die intervertebrale kontakoppervlaktes kan voorstel. Die ontwerp van ʼn PVKISI vereis baie werksure van ʼn gekwalifiseerde ingenieur of ontwerper, wat veroorsaak dat die vervaardigingskoste van so ʼn implantaat kan verhoog. In dié projek word ʼn gebruikersvriendelike koppelprogram beskryf wat die ontwerpproses semi-outomatiseer. Daar sal slegs beperkte bystand van die betrokke medici vereis word. Dié koppelprogram behoort heelwat te bespaar aan die hoeveelheid werksure bestee aan die ontwerp van die PVKISI, wat direk die koste van ʼn implantaat sal verlaag. Die kostes vir die vervaardiging van die PVKISI met DMLS is ook ondersoek om te bepaal hoe kostes bespaar kan word. Daar is getoon dat ʼn pasklaar-prostese se kontakoppervlaktes met ʼn akkuraatheid van 0.37 mm, deur snelle prototipering, vervaardig kan word. Deur van die koppelprogram, wat in die studie beskryf word, gebruik te maak, sal dit moontlik wees om ʼn pasklaar-protese binne 27 minute te ontwerp

The New Breed:How to Re-Imagine Living with Robots

In The New Breed: How to Think About Robots (2021), Kate Darling argues that to understand our future with robots a lot can be learned from studying our relationship with animals. The animal analogy raises important new questions, can help to design our futures with robots, and helps to develop an approach to robot rights. However, as Darling also acknowledges, this analogy has limits. First, the question remains whether our relationship with animals, and especially its inconsistent ethics, is a desirable state of affairs. Second, human-animal relationships fall short of offering new ways for humans to care for each other, for animals, and for the technologies they use. Third, most of Darling’s arguments are interlaced with cross-cultural comparisons that demonstrate how we have related to animals in fundamentally similar ways throughout history and across cultures. In this review essay, we turn to the ‘fringes’ or ‘loose ends’ of Darling’s analogy as starting points for thinking with Darling. In particular, we attempt to push forward conversations on human accountabilities and responsibilities in more-than-human relationships.</div
