Abstract

Although activities of daily living are often difficult for individuals with cognitive impairments, their autonomy and independence can be fostered through interactive technologies. The use of traditional computer interfaces has however proved to be difficult for these users, bringing to the surface the need for novel interaction methods. This paper proposes Let’s Cook, an innovative Augmented Reality game, designed to teach children with cognitive impairments how to prepare simple meals, following a playful approach. Let’s Cook supports multimodal interaction techniques utilizing tangible objects on a table-top surface, as well as multimedia output. Additionally, it can be personalized to accommodate the diverse needs of children with cognitive impairments by employing individual user profiling. The system is currently installed in the kitchen of the Rehabilitation Centre for Children with Disabilities in Heraklion, Crete where it was evaluated by the students.

Leonidis A., Arampatzis D., Korozi M., Adami I., Ntoa S., Stephanidis C. (2017) Home Game: an Educational Game for Children with Cognitive Impairments In the Proceeding of the 2017 conference on interaction design and children, June 27-30, 2017, Stanford, CA, USA. ACM

Abstract

This paper describes an educational game that aims to familiarize cognitive impaired children with household objects, the overall home environment and the daily activities that take place in it. In addition to touch-based interaction, the game supports physical manipulation through printed cards on a tabletop setup, using a webcam to detect and track the cards placed on the game board.

Interacting with augmented paper maps: a user experience study

Margetis, G. Ntoa, S., Antona, M., Stephanidis, C. (2017) Interacting with augmented paper maps: a user experience study 12th biannual Conference of the Italian SIGCHI Chapter (CHITALY 2017). 18th -20th September, Cagliari, Italy.

Abstract

This paper presents a user experience study of interaction with printed maps for providing digitally augmented tourism information. The Interactive Maps system has been implemented based on an interactive printed matter framework which provides all the necessary components for developing smart applications that offer printed matter interaction, and has been deployed and evaluated in the context of the publicly available Tourism InfoPoint of the Municipality of Heraklion. The results of the evaluation highlight that interacting with digitally augmented paper is quite easy and natural, while the overall user experience is positive.

Designing intelligent games adapting to children’s playing maturity

Abstract

Play is a voluntary activity in which individuals involve for pleasure. It is very important for children because through playing they learn to explore, develop and master physical and social skills. Play development is part of the child’s growth and maturation process since birth. As such, it is widely used in the context of Occupational Therapy (OT). Occupational therapists use activity analysis to shape play activities for therapeutic use and promote an environment where the child can approach various activities while playing. This paper builds on knowledge stemming from the processes and theories used in OT and activity analysis to present the design, implementation and deployment of a new version of the popular farm game as deployed within an Ambient Intelligence (AmI) simulation space. Within this space, an augmented interactive table and a three-dimensional avatar are employed to extend the purpose and objectives of the game, thus also expanding its applicability to the age group of preschool children from 3 to 6 years old. More importantly, through the environment, the game monitors and follows the progress of each young player, adapts accordingly and provides important information regarding the abilities and skills of the child and their development over time. The developed game was evaluated through a small scale study with children of the aforementioned age groups, their parents, and child care professionals. The outcomes of the evaluation were positive for all target groups and provided significant evidence regarding its potential to offer novel play experience to children, but also act as a valuable tool to child care professionals.

Touch detection for planar interactive displays based on lateral depth views

A. Ntelidakis, X. Zabulis, D. Grammenos, P. Koutlemanis (2016) Touch detection for planar interactive displays based on lateral depth views Multimedia Tools and Applications, pp 1-25, 28 June 2016

Abstract

This work regards fingertip contact detection and localization upon planar surfaces, for the purpose of providing interactivity in augmented, interactive displays that are implemented upon these surfaces. The proposed approach differs from the widely employed approach where user hands are observed from above, in that user hands are imaged laterally. An algorithmic approach for the treatment of the corresponding visual input is proposed. The proposed approach is extensively evaluated and compared to the top view approach. Advantages of the proposed approach include increased sensitivity, localization accuracy, scalability, as well as, practicality and cost efficiency of installation.

Helfert (Eds.), Proceedings of the 6th International Conference on Cloud Computing and Services Science (CLOSER 2016), Rome, Italy, 23-25 April (Vol. 1, pp. 388-395). Portugal: SCITEPRESS.

Abstract

This paper reports on ongoing work regarding interactive 3D visualization of large scale data centres in the context of Big Data and data centre infrastructure management. The proposed approach renders a virtual area of real data centres preserving the actual arrangement of their servers and visualizes their current state while it notifies users for potential server anomalies. The visualization includes several condition indicators, updated in real time, as well as a color-coding scheme for the current servers’ condition referring to a scale from normal to critical. Furthermore, the system supports on demand exploration of an individual server providing detailed information about its condition, for a specific timespan, combining historical analysis of previous values and the prediction of potential future state. Additionally, natural interaction through hand-gestures is supported for 3D navigation and item selection, based on a computer-vision approach.

Abstract

Adaptation and content personalization in the context of multi user museum exhibits Conference Paper · June 2016 with 2 Reads Conference: 1st Workshop on Advanced Visual Interfaces for Cultural Heritage co-located with the International Working Conference on Advanced Visual Interfaces (AVI 2016), At Bari, Italy 1st Nikolaos Partarakis 4.18 · Foundation for Research and Technology - Hellas 2nd Margherita Antona 15.64 · Foundation for Research and Technology - Hellas 3rd Emmanouil Zidianakis 1.71 · Foundation for Research and Technology - Hellas 4th Constantine Stephanidis Abstract Two dimensional paintings are exhibited in museums and art galleries in the same manner since at least three centuries. However, the emergence of novel interaction techniques and metaphors provides the opportunity to change this status quo, by supporting mixing physical and digital Cultural Heritage experiences. This paper presents the design and implementation of a technological framework based on Ambient Intelligence to enhance visitor experiences within Cultural Heritage Institutions (CHIs) by augmenting two dimensional paintings. Among the major contributions of this research work is the support of personalized multi user access to exhibits, facilitating also adaptation mechanisms for altering the interaction style and content to the requirements of each CHI visitor. A standards compliant knowledge representation and the appropriate authoring tools guarantee the effective integration of this approach to the CHI context.

Abstract

This paper presents the conversion of an electric cargo vehicle into a portable platform for interacting with information applications. The cargo vehicle hosts 2 seats for the driver and 1 extra passenger, and 3 interactive systems installed at the cargo’s right, left and back exterior side. The vehicle is intended to follow predefined routes from central ports to the nearest city center, making long term stops. During stops, embedded interactive systems entertain and provide visitors and other passersby with information of local interest. This papers focuses on the vehicle’s conversion process, from the installation of the necessary hardware components needed by the interactive systems to the development of a portable control panel designed to address the driver’s needs.
