- Overview of some Command Modes for Human-Robot Interaction SystemsPublication . Zaatri, AbdelouahabInteraction and command modes as well as their combination are essential features of modern and futuristic robotic systems interacting with human beings in various dynamical environments. This paper presents a synthetic overview concerning the most command modes used in Human-Robot Interaction Systems (HRIS). It includes the first historical command modes which are namely tele-manipulation, off-line robot programming, and traditional elementary teaching by demonstration. It then introduces the most recent command modes which have been fostered later on by the use of artificial intelligence techniques implemented on more powerful computers. In this context, we will consider specifically the following modes: interactive programming based on the graphical-user-interfaces, voice-based, pointing-on-image-based, gesture-based, and finally brain-based commands.
- Augmented Reality for a New Reality: Using UTAUT-3 to Assess the Adoption of Mobile Augmented Reality in Tourism (MART)Publication . Pinto, Agostinho Sousa; Abreu, António; Costa, Eusébio; Paiva, JerónimoFew industries were more affected by the COVID-19 pandemic than tourism. One of Europe´s leading tourist destinations, Porto had undergone a major tourism boom until the start of pandemic. Mobile Augmented Reality (MAR) is one of the many emerging technologies that has great potential for tourist operators. Using this technology, they can create innovative tourism products that will help them recover from the present crisis. As a result, in this study, we will empirically test the latest version of the Unified Theory of Acceptance and Use of Technology (UTAUT) model to explore the factor leading to the adoption Mobile Augmented Reality in Tourism (MART) in Porto. In doing so, we aim to contribute to growing literature on the topic of Mobile Augmented Reality (MAR). The originality of this study lies in the use of an extended UTAUT model with greater predictive power and the exploration of the moderative role of gender, age and experience. To the data obtained from a random sample of 201 respondents who voluntarily answered an anonymous online questionnaire, we applied structural equational modeling and partial least squares (SEM-PLS) analysis to test the model. Our findings show that habit, hedonic motivations and facilitating conditions are the determinants of the use of MART.
- Management Challenges in Bimodal IT OrganizationsPublication . Stamoulis, DimitriosMost information technology (IT) organizations are experimenting on adoption of the dual mode of operation, involving traditional and agile methods of work. These two incompatible development worlds need to be in sync for IT to operate effectively. However, both types of operation map onto generic project management principles allowing the manageability of IT projects. Management issues and challenges are presented as points for paying particular attention when managing bimodal (both waterfall and agile practices) IT organizations in two stages: the transition from the traditional to the bimodal and after the adoption of bimodal. These issues and challenges belong to the management and organizational, people, process and technology categories. The management challenges presented in this study are important for the decisions to be made regarding the management and governance of projects into bimodal IT organizations.
