Purpose – The purpose of this paper is to consider the two main existing text input techniques based on “eye gestures” – namely EyeWrite and Eye-S – and compare them to each other and to the traditional “virtual keyboard” approach. Design/methodology/approach – The study primarily aims to assess user performance at the very beginning of the learning process. However, a partial longitudinal evaluation is also provided. Two kinds of experiments have been implemented involving 14 testers. Findings – Results show that while the virtual keyboard is faster, EyeWrite and Eye-S are also appreciated and can be viable alternatives (after a proper training period). Practical implications – Writing methods based on eye gestures deserve special attention, as they require less screen space and need limited tracking precision. This study highlights the fact that gesture-based techniques imply a greater initial effort, and require proper training not only to gain knowledge of eye interaction per se, but also for learning the gesture alphabet. The author thinks that the investigation can drive the designers of gaze-controlled writing techniques based on gestures to put more consideration on the intuitiveness of gestures themselves, as they may greatly influence user performance in the first stages of the learning process. Originality/value – This is the first study comparing EyeWrite and Eye-S. Moreover, unlike other analyses, the investigation is mainly aimed at assessing user performance with the three text entry methods at the inception of the learning procedure.

Input Techniques

Existing consumer VR systems support text input using handheld controllers in combination with virtual keyboards and many designers have attempted to build on these widely used techniques. However, information on current and well-established VR text-input techniques is lacking. In this work, we conduct a comparative empirical evaluation of four controller-based VR text-input techniques, namely, raycasting, drum-like keyboard, head-directed input, and split keyboard. We focus on their text-entry rate and accuracy, usability, and user experience. Twenty-two participants evaluated the techniques by completing a typing session, answering usability and user-experience questionnaires, and participating in a semi-structured interview. The drum-like keyboard and the raycasting techniques stood out, achieving good usability scores, positive experiential feedback, satisfactory text-entry rates, and moderate error rates that can be reduced in future studies. The specific documented usability and experiential characteristics of the techniques are presented and discussed herein.

Purpose Knowledge acquired from sources of unverified information such as gossip, partial truths or lies, in this paper it is termed as “counter-knowledge.” The purpose of this paper is to explore this topic through an exploration of the links between a Hospital-in-the-Home Units (HHUs) learning process (LP), counter-knowledge, and the utilization of communication technologies. The following two questions are addressed: Does the reduction of counter-knowledge result in the utilization of communication technologies? Does the development of counter-knowledge hinder the LP? Design/methodology/approach This paper examines the relevance of communication technologies to the exploration and exploitation of knowledge for 252 patients of a (HHU) within a Spanish regional hospital. The data collected was analyzed using the PLS-Graph. Findings To HHU managers, this study offers a set of guidelines to assist in their gaining an understanding of the role of counter-knowledge in organizational LPs and the potential contribution of communication technologies. Our findings support the proposition that the negative effects of counter-knowledge can be mitigated by using communication technologies. Originality/value It is argued in this paper that counter-knowledge may play a variety of different roles in the implementation of LPs. Specifically, the assignment of communication technologies to homecare units has given them the means to filter counter-knowledge and prevent users from any possible problems caused by such counter-knowledge.

In this paper, we investigate the possibilities for augmenting interaction around the mobile device, with the aim of enabling input techniques that do not rely on typical touch-based gestures. The presented research focuses on utilizing a built-in magnetic field sensor, whose readouts are intentionally affected by moving a strong permanent magnet around a smartphone device. Different approaches for supporting magnet-based Around-Device Interaction are applied, including magnetic field fingerprinting, curve-fitting modeling, and machine learning. We implemented the corresponding proof-of-concept applications that incorporate magnet-based interaction. Namely, text entry is achieved by discrete positioning of the magnet within a keyboard mockup, and free-move pointing is enabled by monitoring the magnet’s continuous movement in real-time. The related solutions successfully expand both the interaction language and the interaction space in front of the device without altering its hardware or involving sophisticated peripherals. A controlled experiment was conducted to evaluate the provided text entry method initially. The obtained results were promising (text entry speed of nine words per minute) and served as a motivation for implementing new interaction modalities. The use of neural networks has shown to be a better approach than curve fitting to support free-move pointing. We demonstrate how neural networks with a very small number of input parameters can be used to provide highly usable pointing with an acceptable level of error (mean absolute error of 3 mm for pointer position on the smartphone display).

Efficiency And Productivity

Purpose The purpose of this paper is to longitudinally assess the technical efficiency and productivity, considering investment projects and technological change, in a second-generation petrochemical company. Design/methodology/approach The study uses data envelopment analysis (DEA) together with the Malmquist index to measure efficiency during the analysis periods. The working method consists of four main phases, namely development of the conceptual model, construction of the mathematical model, application of model to the case, and analysis of the results. The study utilizes a quantitative approach with descriptive goals seeking to evaluate the impacts of technical changes on the operational efficiency and productivity of the production process. Findings The use of DEA associated with the Malmquist index proved to be viable for analyzing a single company and identifying efficiency improvements, as well as the impacts of the learning process and the implementation of improvement projects. However, the results of the improvement projects and learning process were not representative and had no statistical significance on the actual change in efficiency of the company during the periods analyzed. For the case in question, the learning process and continuous improvement were not observed during all study periods. Practical implications The proposition that the improvement projects and investments implemented increased the efficiency of the company was rejected. Hence, with this work, it was possible to determine that the company unnecessarily invested resources in projects to increase efficiency. Furthermore, the company could have explored more internal resources before making significant investments in increased efficiency. Originality/value As for the value of this research in the theoretical and academic scope, this paper advances knowledge on the application of DEA because it proposes to establish an internal reference benchmarking for comparison. The literature contains few studies that analyze organizations using continuous processes, such as petrochemical processes, in longitudinal studies as a function of time, especially with the use of DEA.

PurposeThis paper presented the learning process of a group of primary mathematics teachers who participated in two iterations of lesson design, enactment and reflection in a Chinese Lesson Study.Design/methodology/approachAn expansive learning theory was employed to examine the teachers’ learning process in lesson study (LS) on representing fractions on a number line. The evolution of a germ cell was utilized to feature the transformation of the object of activity from abstract to concrete through resolving contradictions among LS members. The videos of lesson planning, research lessons (RLs) and debriefing meetings were collected and analyzed to reveal the expansive learning process.FindingsThe analysis showed that the teachers expanded their learning through transforming the object from diffuse to concrete and expanded through consciously articulating the germ cell. The outcomes of object-oriented activity include improving the enacted lesson which promoted students’ conceptual understanding.Originality/valueThis study made a unique contribution to understanding the learning process of teachers in Chinese LS from the perspective of expansive learning.

Purpose The purpose of this paper is to examine the cultural learning process (namely, the development, practice and enhancement of cultural intelligence (CQ)) of a successful entrepreneur – Harold Bixby, a Pan American Airways expatriate, as reflected in the memoir of his experiences in China during 1933–1938. Design/methodology/approach This study adopts a microhistory approach as a methodology for studying history and the past while ultimately requiring evaluations informed by the present. This paper first identifies the literature gap on CQ development and the need to study historical accounts of the past in assessing the CQ development process. This study then outlines the four key foci of microhistory as a heuristic for making sense of on-going and past accounts of selected phenomena. Findings This paper finds that specific personality traits (namely, openness to experience and self-efficacy), knowledge accumulation through deep cultural immersion (namely, extensive reading/study, visiting/observation and interacting/conversation), critical incident and metacognition all contributed to Bixby’s CQ development, which was a time-consuming process. Originality/value The study contributes to debates around cultural learning and historical organization studies by providing a rich, qualitative study of CQ assessment and CQ development through microhistory. This study highlights the importance of cognitive CQ and the function of extensive reading/studying in the process of knowledge accumulation. This paper draws attention to critical incidents as an underexplored way of learning tacit knowledge. Moreover, this study suggests metacognitive CQ can be enhanced through meditative and reflexive teaching and research practices. These findings have significant implications for cross-cultural training programs.

Purpose The purpose of this paper is to contextually theorise the different patterns of emerging multinational companies’ (EMNCs’) learning processes for innovation and the different influences of their technology-driven FDIs (TFDIs) on the processes. Design/methodology/approach A comparative case study method and process tracing technique are employed to investigate how and why firms’ learning processes for innovation took place, how and why the TFDIs emerged and influenced the firms’ learning processes in different ways. Findings The paper identifies two different patterns of learning process for innovation (Glider model vs Helicopter model) and two different roles of the case firms’ TFDIs (accelerator vs starter) in the different contexts of their learning processes. It is found that the capability building of the domestic wind energy industry has an important influence on the case of EMNCs’ learning processes and thus on the roles of their TFDIs. Research limitations/implications The limitation of the paper lies in its small number of cases in a specific industry of a specific country. The two contextually identified learning models and roles of TFDIs may not be applied to other industries or other countries. Future research should investigate more cases in broader sectoral and geographic scope to test the models and also to identify new models. Practical implications For EMNCs, who wants to use the Helicopter model to rapidly gain production and innovation capability, cross-cultural management and integration management are crucial to practitioners. For emerging countries with ambitions to explore the global knowledge and technology pool, besides of the EMNC’s capability building, the capability building in the domestic industries should not be overlooked by policy makers. Originality/value The paper develops a dynamic and contextual analytical framework which helps to answer the important questions about how and under what context a TFDI emerges and influences firm’s learning process for innovation. It theorises the EMNCs’ learning process and TFDIs in the context of the development of the domestic industry. It strengthens the explanatory power of the learning-based view and adds new knowledge to the current FSA/CSA discourse in the international business literature.

Purpose The growing use of internet-based learning (IBL) platforms in institutions of higher education is producing profound changes in the traditional teaching learning process worldwide. This paper aims to identify and understand the ways in which higher education institutions draw benefits by the use of such means, synthesizing the literature research. Design/methodology/approach The study synthesized the literature research by using a mixed method approach in which both Web of Science (WoS) and bibliographic techniques were used to retrieve the relevant data base. Findings The comprehensive review of the literature suggests that communication technology (CT), massive open online courseware (MOOCs), social networking sites (SNSs), blogs, real simple syndication (RSS) and YouTube are creating new possibilities and avenues of collaborative learning by transforming the traditional class and teacher-centric system. Research limitations/implications Multiplicity of the IBL platforms and rapid technological obsolesce are some of the limitations of this paper. Originality/value The findings of this study are highly useful in developing a strategic framework to accelerate the integration of IBL platforms to make teaching learning process more interactive and informative.
