This is evident from the fact that most research studies are either Eurocentric or American-centric. Hence, this research aimed to identify consumer-centric factors for planning considerations in implementation of smart meters in South Africa. We used various behavioural theoretical models found in literature to identify potential factors relevant to this study. Based on quantitatively gathered data (n = 705), a structural equation model (SEM) was used to evaluate the identified factors. This study found that only ten consumer-centric factors were significant to smart meter consumers. These factors include behavioural intention, attitude, trust in technology, social norms, facilitating conditions, perceived usefulness, perceived ease of use, privacy risk, monetary cost, and perceived value. In conclusion, the study shows that not all factors suggested within the European and American context are relevant for smart meter implementation within the South African context. Hence, results of this study hold some practical implications in assisting utility companies in identifying consumer-centric factors that are relevant to the South African population. Finally, consumer-centric factors can be used by policy makers and energy regulators as baseline factors for future pervasive technology acceptance studies.","PeriodicalId":55859,"journal":{"name":"South African Computer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44495346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use ofsoftware architecture becomes increasingly important as the complexity ofartefacts increases.\u0000Augmented Reality blends the real world observed through a computerinterface, with a computer generated virtual world. With the advent ofpowerful mobile devices, Mobile Augmented Reality (MAR)applications have become increasingly feasible, however the increased power hasled to increased complexity. Most MAR research has been directed towardstechnologies and not design resulting in a dearth of architecture and design literature for MAR. This research is targeted at addressing this void.\u0000The main requirement that a MAR architecture must meet isidentified as being the efficient real-time processing of data streams such asvideo frames and sensor data. A set of highly parallelised architecturalpatterns are documented within the context of MAR that meet thisrequirement.

Although there are short, medium and long-term dimensions to success, the reality is that they are inseparably linked. Time plays a significant role as a stakeholder, such as a project manager who has short-term interests. In contrast, a business executive has long-term interests for the organisation as a whole. Project success is arguably a continuum where each dimension plays a role in realising long-term benefits for the organisation. This research investigates IS projects specifically to understand the argued correlation between short, medium and long-term project success dimensions. A total of 612 valid responses were collected through an online questionnaire. Quantitative analysis through PLS-SEM was conducted to reveal the correlation between success dimensions. The overall implication is that short-term IS project success does not directly correlate with long-term IS project success. However, there is a clear correlation between the time phases of IS project success. This research shows medium-term success mediates the relationship and correlation of short and long-term success. While literature acknowledges the relationship literature, this research confirms this notion and proves a significant correlation between each IS project success dimension over time.","PeriodicalId":55859,"journal":{"name":"South African Computer Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41576538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the use of tactile feedback to convey information about this environment is often lacking in VR applications. New methods for inducing a degree of tactile feedback in users are described, which induced the illusion of a tactile experience, referred to as pseudo-tactile feedback. These methods utilised shared properties between audio and tactile feedback that can be crossmodally mapped between the two modalities in the design of a virtual reality prototype for a qualitative usability study in order to test the effectiveness and underlying causes of such feedback in the total absence of any real-world tactile feedback. Results show that participants required believable audio stimuli that they could conceive as real-world textures as well a sense of hand-ownership to suspend disbelief and construct an internally consistent mental model of the virtual environment. This allowed them to conceive believable tactile sensations that result from interaction with virtual objects inside this environment.","PeriodicalId":55859,"journal":{"name":"South African Computer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46297110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This involves the use of an electronic health record (EHR) which is a longitudinal electronic record of a patient's information. The EHR includes all the patient's encounters that have been made with different health facilities. In the national context, the EHR is also known as a national EHR, which enables the sharing of patient information between points of care. However, a lack of interoperability exists between many South African health information systems making communication between these disparate systems impossible. As a result, the sharing of patient information is inhibited and the benefit of improving healthcare delivery cannot be realised. This paper proposes a system architecture for addressing interoperability challenges and indicates how interoperability can be ensured in a national EHR system. The proposed system architecture is differentiated from other national EHR system architectures found in the literature in order to emphasise its novelty. Secondary data obtained from a systematic literature review was analysed using content analysis, resulting in 9482 tags which informed the development of the proposed system architecture.","PeriodicalId":55859,"journal":{"name":"South African Computer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48606196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
