Smartphones
Many of the research approaches to smartphones actually regard them as more or less transparent points of access to other kinds of communication experiences. That is, rather than considering the smartphone as something in itself, the researchers look at how individuals use the smartphone for their communicative purposes, whether these be talking, surfing the web, using on-line data access for off-site data sources, downloading or uploading materials, or any kind of interaction with social media. They focus not so much on the smartphone itself but on the activities that people engage in with their smartphones
Pedestrian Detection with Wearable Cameras for the Blind: A Two-way Perspective
Blind people have limited access to information about their surroundings,
which is important for ensuring one's safety, managing social interactions, and
identifying approaching pedestrians. With advances in computer vision, wearable
cameras can provide equitable access to such information. However, the
always-on nature of these assistive technologies poses privacy concerns for
parties that may get recorded. We explore this tension from both perspectives,
those of sighted passersby and blind users, taking into account camera
visibility, in-person versus remote experience, and extracted visual
information. We conduct two studies: an online survey with MTurkers (N=206) and
an in-person experience study between pairs of blind (N=10) and sighted (N=40)
participants, where blind participants wear a working prototype for pedestrian
detection and pass by sighted participants. Our results suggest that both of
the perspectives of users and bystanders and the several factors mentioned
above need to be carefully considered to mitigate potential social tensions.Comment: The 2020 ACM CHI Conference on Human Factors in Computing Systems

Augmenting the field experience: a student-led comparison of techniques and technologies
In this study we report on our experiences of creating and running a student fieldtrip exercise which allowed students to compare a range of approaches to the design of technologies for augmenting landscape scenes. The main study site is around Keswick in the English Lake District, Cumbria, UK, an attractive upland environment popular with tourists and walkers. The aim of the exercise for the students was to assess the effectiveness of various forms of geographic information in augmenting real landscape scenes, as mediated through a range of techniques and technologies. These techniques were: computer-generated acetate overlays showing annotated wireframe views from certain key points; a custom-designed application running on a PDA; a mediascape running on the mScape software on a GPS-enabled mobile phone; Google Earth on a tablet PC; and a head-mounted in-field Virtual Reality system. Each group of students had all five techniques available to them, and were tasked with comparing them in the context of creating a visitor guide to the area centred on the field centre. Here we summarise their findings and reflect upon some of the broader research questions emerging from the project
Examining the role of smart TVs and VR HMDs in synchronous at-a-distance media consumption
This article examines synchronous at-a-distance media consumption from two perspectives: How it can be facilitated using existing consumer displays (through TVs combined with smartphones), and imminently available consumer displays (through virtual reality (VR) HMDs combined with RGBD sensing). First, we discuss results from an initial evaluation of a synchronous shared at-a-distance smart TV system, CastAway. Through week-long in-home deployments with five couples, we gain formative insights into the adoption and usage of at-a-distance media consumption and how couples communicated during said consumption. We then examine how the imminent availability and potential adoption of consumer VR HMDs could affect preferences toward how synchronous at-a-distance media consumption is conducted, in a laboratory study of 12 pairs, by enhancing media immersion and supporting embodied telepresence for communication. Finally, we discuss the implications these studies have for the near-future of consumer synchronous at-a-distance media consumption. When combined, these studies begin to explore a design space regarding the varying ways in which at-a-distance media consumption can be supported and experienced (through music, TV content, augmenting existing TV content for immersion, and immersive VR content), what factors might influence usage and adoption and the implications for supporting communication and telepresence during media consumption
Human computer interaction for international development: past present and future
Recent years have seen a burgeoning interest in research into the use of information and communication technologies (ICTs) in the context of developing regions, particularly into how such ICTs might be appropriately designed to meet the unique user and infrastructural requirements that we encounter in these cross-cultural environments. This emerging field, known to some as HCI4D, is the product of a diverse set of origins. As such, it can often be difficult to navigate prior work, and/or to piece together a broad picture of what the field looks like as a whole. In this paper, we aim to contextualize HCI4D—to give it some historical background, to review its existing literature spanning a number of research traditions, to discuss some of its key issues arising from the work done so far, and to suggest some major research objectives for the future
Exploring Digital Marketing Optimization: Enhancing Company Performance with a Focus on the FMCG Industry in Lebanon
In the ever-evolving landscape of digital marketing, companies within the Fast-Moving Consumer Goods (FMCG) industry in Lebanon are recognizing the imperative need to optimize their digital marketing strategies to enhance overall performance. This study delves into the intricacies of digital marketing optimization, with an emphasis on perceived ease of use, perceived usefulness, user experience, and consumer engagement as pivotal themes impacting company performance. Employing a qualitative research methodology, in-depth insights were garnered from 15 industry professionals through semi-structured interviews. These individuals were carefully selected for their expertise and firsthand experience with digital marketing within the Lebanese FMCG sector. The analysis of the qualitative data led to the extraction of nuanced understandings regarding how perceived ease of use and perceived usefulness directly influence the user experience and, subsequently, consumer engagement in digital platforms. The study highlights the critical role of user-friendly interfaces and valuable content in fostering positive consumer experiences, which in turn, amplify engagement rates. Moreover, the research identifies the chain effect that starts with the initial consumer interaction with digital marketing campaigns and cascades into long-term company performance metrics. The findings reveal that the FMCG companies in Lebanon are at a pivotal junction, where embracing digital marketing optimization can lead to significant competitive advantages. Companies that adeptly leverage the ease of use and usefulness of their digital content can create enhanced user experiences, thereby fostering deeper levels of consumer engagement.info:eu-repo/semantics/publishedVersio
