a Natural User Interface to integrate citizen science and physical exercise
PLOS ONE, 2017Co-Authors: Jeffrey Lau, Eduardo Palermo, Oded Nov, P Cappa, Maurizio PorfiriAbstract:Citizen science enables volunteers to contribute to scientific projects, where massive data collection and analysis are often required. Volunteers participate in citizen science activities online from their homes or in the field and are motivated by both intrinsic and extrinsic factors. Here, we investigated the possibility of integrating citizen science tasks within physical exercises envisaged as part of a potential rehabilitation therapy session. The citizen science activity entailed environmental mapping of a polluted body of water using a miniature instrumented boat, which was remotely controlled by the participants through their physical gesture tracked by a low-cost markerless motion capture system. Our findings demonstrate that the Natural User Interface offers an engaging and effective means for performing environmental monitoring tasks. At the same time, the citizen science activity increases the commitment of the participants, leading to a better motion performance, quantified through an array of objective indices. The study constitutes a first and necessary step toward rehabilitative treatments of the upper limb through citizen science and low-cost markerless optical systems.

a Natural User Interface to drive a robotic fish
Volume 1: Adaptive and Intelligent Systems Control; Advances in Control Design Methods; Advances in Non-Linear and Optimal Control; Advances in Roboti, 2015Co-Authors: Mauro De Bellis, Paul Phamduy, Maurizio PorfiriAbstract:Interactive control modes for robotic fish based informal science learning activities have been shown to increase User interest in STEM careers. This study explores the use of Natural User Interfaces to engage Users in an interactive activity and excite them about the possibility of a robotics career. In this work, we propose a novel Natural User Interface platform for enhancing participant interaction by controlling a robotic fish in a set of tasks. Specifically, we develop and characterize a new platform, which utilizes a Microsoft Kinect and an ad-hoc communication protocol. Preliminary studies are conducted to assess the usability of the platform.Copyright © 2015 by ASME

controlling a robotic fish via a Natural User Interface for informal science education
IEEE Transactions on Multimedia, 2015Co-Authors: Paul Phamduy, Mauro Debellis, Maurizio PorfiriAbstract:Informal science education is a key contributing factor to scientific literacy, which determines our capacity as a society to technologically progress and make cognizant decisions on pressing issues of global scale. Both the fields of robotics and Natural User Interfaces have been separately proposed as effective means to aid informal science education, by increasing Users’ engagement through multiple interactive features. Here, we demonstrate the integration of these two fields of investigation toward a novel educational platform, revolving around the control of a robotic fish via a Natural User Interface. Users control the robotic fish through upper limb gestures that are captured by the Kinect. The robotic fish incorporates a temperature sensor, which collects data in a tank instrumented with heating and cooling sources. Participants observe the measurements they are recording in real-time to map the environment. Self-reported post-activity surveys and behavioral coding data on young Users were collected to assess their level of engagement in the activity and their perception of the system. Our results indicate that the robotic fish is intuitive to drive with the Natural User Interface, the activity of collecting water temperature is interesting, and robotics may be a viable and accessible career option.

the Natural User Interface
Brave NUI World#R##N#Designing Natural User Interfaces for Touch and Gesture, 2011Co-Authors: Daniel Wigdo, Dennis WixoAbstract:This chapter discusses touch and gestural interaction as one modality enabling the construction of a Natural User Interface (NUI). In the Natural User Interface, Natural refers to the User's behavior and feeling during the experience rather than the Interface being the product of some organic process. The production of this conclusion is the end result of a rigorous design, leveraging the potential of modern technologies to better mirror human capabilities. A NUI can be created with other input modalities as well. Indeed, one could imagine following the design guidelines one lays out to create a new kind of Interface for the mouse and keyboard, voice commands, in-air gesturing, mobile phones, and so on. Input and output technologies offer the opportunity to create a more Natural User Interface; they do not, in and of themselves, define or guarantee it. The Natural User Interface lies in the UI and experiences one creates for using with those technologies and how they leverage the potential of new technologies to better mirror human capabilities, optimize the path to expert, apply to given contexts and tasks, and fulfill the needs.

using metaphors to create a Natural User Interface for microsoft surface
Human Factors in Computing Systems, 2010Co-Authors: Kay Hofmeeste, Dennis WixoAbstract:Creating a new model of human computer interaction is not straightforward. Only a handful of such models have been commercially successful. Those that have, such as the graphical User Interface (GUI), can provide valuable lessons. When we were challenged to develop a new Natural User Interface design for Microsoft Surface, we drew from these lessons and from modern User research techniques. A prominent starting point resulting from this was using metaphors to develop the new User Interface. We used metaphors for two reasons: To create a User Interface world that was understandable and predictable for our Users, and to guide the design team in creating the detailed User Interface design. We continued this practice in the User research: We focused on which metaphors worked best in the studies, and learned if Users understood the metaphors we were using and which metaphor they preferred. This case study describes the process we followed, and the lessons we learned from this.

implementing a Natural User Interface for camera phones using visual tags
Australasian User Interface Conference, 2006Co-Authors: Sanni Siltane, Jouko HyvakkaAbstract:A conventional keypad User Interface of mobile phones is unsuitable for some modern situations. Here we present a visual tagging system and show how such a system can be used for fast and efficient User Interface, utilizing a camera phone as a pointing device. We also present our two optional mobile phone implementations, one aiming for very fast processing and the other for high detection resolution. These efficient implementations are achieved by taking into account the strict constraints of the mobile environment. We present a flexible system where varying physical and storage sizes of the visual tag can be used in different applications through one Interface application and we present some performance statistics of our implementations. We also identify some of the constraints on the mobile device programming environment concentrating on Symbian Series 60 mobile phones.
