Comparison of Gesture, Gamepad, and Gaze-based Locomotion for VR Worlds

In this paper we present a VR locomotion technique based on the Leap Motion device and compare it to other often-used locomotion techniques – gaze-directed locomotion and gamepad-based locomotion. We performed a user experiment to evaluate the three techniques based on their performance (time to complete the task), comfort (through the ISO 9241-9 assessment of comfort questionnaire), and simulation sickness (through the Simulation Sickness Questionnaire). Results indicate that the gamepad technique is both faster and more comfortable than either the Leap Motion-based or the gaze-directed techniques.info:eu-repo/semantics/publishedVersio

Dynamic graphical user interface generation for web-based public display applications

Public digital displays are moving towards open display networks, resulting in a shift in the focus from single-purpose public displays that are developed with a single task or application in mind, to general- purpose displays that can run several applications, developed by different vendors. In this new paradigm, it is important to facilitate the development of interactive public display applications and provide programmers with toolkits for incorporating interaction features. An important function of such toolkits is to support interaction with public displays through a users' smartphone, allowing users to discover and interact with the public display applications configured in a given display. This paper describes our approach to providing dynamically generated graphical user interfaces for public display applications that is part of the PuReWidgets toolkit

PuReWidgets : a programming toolkit for interactive public display applications

Interaction is repeatedly pointed out as a key enabling element towards more engaging and valuable public displays. Still, most digital public displays today do not support any interactive features. We argue that this is mainly due to the lack of efficient and clear abstractions that developers can use to incorporate interactivity into their applications. As a consequence, interaction represents a major overhead for developers, and users are faced with inconsistent interaction models across different displays. This paper describes the results of a study on interaction widgets for generalized interaction with public displays. We present PuReWidgets, a toolkit that supports multiple interaction mechanisms, automatically generated graphical interfaces, asynchronous events and concurrent interaction. This is an early effort towards the creation of a programming toolkit that developers can incorporate into their public display applications to support the interaction process across multiple display systems without considering the specifics of what interaction modality will be used on each particular display.Fundação para a Ciência e a Tecnologia (FCT

Evaluation of a programming toolkit for interactive public display applications

As a consequence, interaction represents a major overhead for developers, and users are faced with inconsistent interaction models across different displays. This paper describes the results of the evaluation of a widget toolkit for generalized interaction with public displays. Our toolkit was developed for web-based applications and it supports multiple interaction mechanisms, automatically generated graphical interfaces, asynchronous events and concurrent interaction. We have evaluated the toolkit along various dimensions - system performance, API usability, and real-world deployment - and we present and discuss the results in this paper.(undefined

Creating web-based interactive public display applications with the PuReWidgets toolkit

Interaction is repeatedly pointed out as a key enabling element towards more engaging and valuable public displays. Still, most digital public displays today do not support any interactive features. We believe that this is mainly due to the lack of e!cient and clear abstractions that developers can use to incorporate interactivity into their applications. In this demo we present PuReWidgets, a toolkit that developers can use in their public display applications to support the interaction process across multiple display systems, without considering the specifics of what interaction modality will be used on each particular display. PuReWidgets provides high-level widgets to application programmers, and allows users to interact via various interaction mechanisms, such as graphical user interfaces for mobile devices, QR codes, SMS, etc.Fundação para a Ciência e a Tecnologia (FCT
