In the current digital age, the adoption of natural interfaces between humans and machines is increasingly important. This trend is particularly significant in the education sector where interactive tools and applications can ease the presentation and comprehension of complex concepts, stimulate collaborative work, and improve teaching practices. An important step towards this vision, interactive whiteboards are gaining widespread adoption in various levels of education. Nevertheless, these solutions are usually expensive, making their acceptance slow, especially in countries with more fragile economies. In this context, we present the low-cost interactive whiteboard (LoCoBoard) project, an open-source interactive whiteboard with low-cost hardware requirements, usually accessible in our daily lives, for an easy installation: a webcam-equipped computer, a video projector, and an infrared pointing device. The detection software framework offers five different Pointer Location algorithms with support for the Tangible User Interface Object protocol and also adapts to support multiple operating systems. We discuss the detailed physical and logical structure of LoCoBoard and compare its performance with that of similar systems. We believe that the proposed solution may represent a valuable contribution to ease the access to interactive whiteboards and increase widespread use with obvious benefits.

The aim of this study is to understand the effectiveness of Improvised Low-cost Wiimote Interactive Whiteboards (Iw-IWB) as educational technology learning tool for Teaching Chinese as Second Language (TCSL) for lower primary pupils in government schools in Malaysia settings. This study are to design and develop an improvised Wiimote IWBs and to identify how far the new innovation leaning tool, the improvised version of interactive whiteboards, could improve pupils’ achievement and their learning motivation in learning Chinese as a Second Language (TCSL). A total number of 46 lower primary pupils study in government schools have involved in this study. The participants were split into two groups (treatment and control). The treatment group used the new developed improvised low-cost Wiimote interactive whiteboards (IWBs) to teach and learn Chinese characters, while the control group used traditional pedagogy. In this study, researchers have design and develop the improvised version of interactive whiteboard and thereafter using pre-test and post-test to identify the effectiveness of the new developed learning tool to enhanced pupils achievement and learning motivation in learning TCSL. The outcomes of the study showed that there has no difference in the students’ achievement and level of motivation between the classes with and without the use of improvised low-cost Wiimote IWB. However, the students’ achievement did show significant improvement before and after the use of Wiimote interactive whiteboard. Implication, improvised low-cost Wiimote IWB is a low-cost alternative which has potential to replace the expensive interactive whiteboard that many schools and teachers could not afford.

Phased Development

This chapter examines how teachers acquire proficiency in the use of interactive whiteboards for the enhancement of whole-class teaching. It suggests that teachers are unlikely to make optimal use of the affordances of the technology through preparatory training alone, and that such an expectation could adversely affect the chances of successful implementation. A phased development of teachers’ capability is described during which those with initially limited technical skills can begin to explore the pedagogic potential of the interactive whiteboard and then progressively develop their technical skills in tandem with the evolution of their pedagogy. The author proposes a process of Transformative Personal Development (TPD) within which initial expert interventions demonstrate what is ultimately achievable and set the agenda for a more sustained period of collaborative work-based learning.

Data Auditing

With the increasing demand for ubiquitous connectivity, wireless technology has significantly improved our daily lives. Meanwhile, together with cloud-computing technology (e.g., cloud storage services and big data processing), new wireless networking technology becomes the foundation infrastructure of emerging communication networks. Particularly, cloud storage has been widely used in services, such as data outsourcing and resource sharing, among the heterogeneous wireless environments because of its convenience, low cost, and flexibility. However, users/clients lose the physical control of their data after outsourcing. Consequently, ensuring the integrity of the outsourced data becomes an important security requirement of cloud storage applications. In this paper, we present Co-Check, a collaborative multicloud data integrity audition scheme, which is based on BLS (Boneh-Lynn-Shacham) signature and homomorphic tags. According to the proposed scheme, clients can audit their outsourced data in a one-round challenge-response interaction with low performance overhead. Our scheme also supports dynamic data maintenance. The theoretical analysis and experiment results illustrate that our scheme is provably secure and efficient.

Interdisciplinarity, multidisciplinarity and counter-disciplinarity are the hallmark of cultural studies and qualitative research, as scholars over the past three decades have discussed through extensive self-reflexive inquiry into their own unstable and ever-shifting methods (Denzin and Lincoln, 2018; Dicks et al., 2006: 78; Grossberg, 2010). Building on the interdisciplinary thought of Jacques Rancière and Caroline Levine on the one hand and traditions of participatory action research and activist anthropology on the other, we bring the methods conversation forward by shifting the focus from disciplines to forms and by making a case for aesthetic practice as qualitative research process. In this paper, the question of methods is approached through the action-based Cartonera Publishing Project with editoriales cartoneras in Latin America – community publishers who make low-cost books out of materials recovered from the street in the attempt to democratise and decolonise literary/artistic production – and specifically through our process-oriented, collaborative work with four cartonera publishers in Brazil and Mexico. Guided by the multiple forms of cartonera knowledge production, which are rooted not in academic research but rather in aesthetic practice and community relations, we offer an innovative ‘trans-formal’ methodological framework, which opens up new pathways for practitioners and researchers to work, think and act across social, cultural and aesthetic forms.

Aerospace heritage requires tools that allow its transfer and conservation beyond photographs and texts. The complexity of these engineering projects can be collected through digital graphic representation. Nevertheless, physical scale models provide additional information of high value when they involve full detailed information, for which the model in engineering was normally one more product of the manufacturing process, which entails a high cost. However, the standardization of digital fabrication allows the manufacture of high-detail models at low cost. For this reason, in this paper a case study of the graphic reengineering and planning stages for digital fabrication of a full-scale high-detail model (HDM) of the spatial instrument of the European Space Agency, named the Solar Orbiter mission Polarimetric and Helioseismic Imager (SO/PHI), is presented. After the analysis of this experience, seven stages of planning and graphic reengineering are proposed through collaborative work for the low cost digital manufacture of HDMs.

Qualitative Thematic Analysis

Previous research has indicated older adults value listening to music as a leisure activity. Yet, recent research into listening practices broadly has often focused on younger adults and the use of newer, digital listening technologies. Nonetheless, the radio, which is familiar to older people who grew up with it at the forefront of family life, is important to consider with regard to listening practices and the potential associated well-being benefits. This research investigated older adults’ everyday radio listening practices, in order to begin to understand how the radio fits into their daily lives and how it might influence their sense of well-being. Twenty-five Australian residents (aged 66–87; 56% female, 44% male) participated in semi-structured, one-to-one interviews. The results of a qualitative thematic analysis revealed themes concerning listening preferences, listening routines, access, and motivations/outcomes. While personal preferences (concerning content, stations, and presenters) were diverse, individuals clearly communicated these as well as their established listening routines and habits. Listener motivations varied: some people focused on the enjoyment that listening to the radio creates while some noted benefits to their well-being, such as relaxation, modifying their mood, and feelings of comfort and community. Radio listening practices can be defined in terms of differing engagement styles, as characterized using continua ranging from passive to active, or focused, listening as well as generalized or specific listening. Based on participants’ experiences, a proposed engagement space model links how people engage with the radio to the possible outcomes mentioned. Importantly, benefits to well-being can result from varied engagement styles. The findings presented provide an in-depth understanding of how the radio fits into older adults’ everyday life, with implications for considering how the radio might be used as a widely accessed, low-cost tool for maintaining and enhancing quality of later life.

The Coefficient Of Friction

In recent years, reproduction of human mechanical hand with upgraded abilities is one of the major concerns. This paper addresses the problems of underactuated robotic hand with low cost design as it avoids electromyogram (EMG) sensors. The main goal is to balance the hand in the way, like grabbing, speed, and power, and provide a more robust and cost effective solution. All fingers have some mechanical consistency for picking up objects in a better way. A Flex sensor is attached to all fingers and it is interfaced with a computer using Arduino UNO microcontroller. The sensor aids the arm in three different directions: at first it senses whether an object is grasped or not. In the second step, it determines the coefficient of friction between the objects. Finally it grasps the object and stops. One of the primary issues of prosthetic hand is to have the capacity to satisfy every detail of torque, speed, and latency. In this research, we have developed a model of robotic hand with some modifications. The adaptability of grasping is compared with the degree of freedom (DOF) along with the quantity of fingers. We are controlling our hands via sensors based signal controlling system. The idea is to design a robotic hand, which has low cost, is easy to use, and is light in weight, which helps the amputees to use it with ease in their daily lives. The efficacy of the proposed control is verified and validated using simulations.
