[EN] Although a myriad of educational applications using tablets and multi-touch technology for kindergarten children have been developed in the last decade, most of these applications do not fully exploit multi-touch technology since the game world used is limited to the screen only. Considering a larger digital space in tablet-based educational scenarios would be beneficial since it would enable the design of engaging activities driven by curiosity, exploration, discovery and decisions on where the next action is situated in the digital virtual space by directional awareness. This paper therefore investigates kindergarten children's abilities to use a virtual world beyond the screen and evaluates three different types of visual prompts for communicating directional awareness. The results obtained show, firstly, that these specific users are able to use the space beyond the screen boundaries and that the evaluated prompts can effectively communicate information to kindergarten children. The paper also makes a set of recommendations to help designers choose the appropriate type of prompt for their application requirements., This work received financial support from Spanish Ministry of Economy and Competitiveness and was funded by the European Development Regional Fund (EDRF-FEDER) in the project TIN2014-60077-R (SUPEREMOS).

[EN] A myriad of educational applications using tablets and multi-touch technology for kindergarten children have been developed in the last decade. However, despite the possible benefits of using visual prompts to communicate information to kindergarteners, these visual techniques have not been fully studied yet. This article therefore investigates kindergarten children¿s abilities to understand and follow several visual prompts about how to proceed and interact in a virtual 2D world. The results show that kindergarteners are able to effectively understand several visual prompts with different communication purposes despite being used simultaneously. The results also show that the use of the evaluated visual prompts to communicate data when playing reduces the number of interferences about technical nature fostering dialogues related to the learning activity guided by the instructors or caregivers. Hence, this work is a starting point for designing dialogic learning scenarios tailored to kindergarten children., This work is supported by the Spanish Ministry of Economy and Competitiveness and funded by the European Development Regional Fund (EDRF-FEDER) with Project TIN2014-60077-R; by VALi+d program from Conselleria d¿Educació, Cultura i Esport (Generalitat Valenciana) under the fellowship ACIF/2014/214, and by the FPU program from Spanish Ministry of Education, Culture, and Sport under the fellowship FPU14/00136

[EN] Gamification has been identified as an interesting technique to foster collaboration in educational contexts. However, there are not many approaches that tackle this in primary school learning environments. The most popular technologies in the classroom are still traditional video consoles and desktop computers, which complicate the design of collaborative activities since they are essentially mono-user. The recent popularization of handheld devices such as tablets and smartphones has made it possible to build affordable, scalable, and improvised collaborative gamifled activities by creating a multi-tablet environment. In this paper we present Quizbot, a collaborative gamifled quiz application to practice different subjects, which can be defined by educators beforehand. Two versions of the system are implemented: a tactile for tablets laid on a table, in which all the elements are digital; and a tangible in which the tablets are scattered on the floor and the components are both digital and physical objects. Both versions of Quizbot are evaluated and compared in a study with eighty primary-schooled children in terms of user experience and quality of collaboration supported. Results indicate that both versions of Quizbot are essentially equally fun and easy to use, and can effectively support collaboration, with the tangible version outperforming the other one with respect to make the children reach consensus after a discussion, split and parallelize work, and treat each other with more respect, but also presenting a poorer time management., We would like to thank Universitat Politecnica de Valencia's Summer School for their collaboration during the development of this study, as well as Colegio Internacional Ausias March for their support in the development of educational content., This work is supported by Spanish Ministry of Economy and Competitiveness and funded by the European Development Regional Fund (EDRF-FEDER) with Project TIN2014-60077-R.

[EN] The ever increasing elderly population requires a revision of technology to make it usable and meaningful for them. Most applications take into account their reduced physical and cognitive abilities in order to provide assistive services, but this paper focuses on building technology to improve these capacities through cognitive games. We present Tangibot, a tangible-mediated robot aimed at enabling more intuitive and appealing interactions. A usability study conducted on subjects at three different levels of cognitive impairment (none, mild, and severe) reveals that it is usable and engaging for users with no or mild cognitive impairment, and even though it is less usable for persons with severe impairment, it triggers positive emotional reactions among them, which makes it promising for their use in therapeutic activities., This work is supported by Spanish Ministry of Economy and Competitiveness and funded by the European Development Regional Fund (EDRF-FEDER) with Project TIN2014-60077-R.

Several studies have shown the suitability of the direct manipulation style and the multi-touch technology for kindergarteners and, as a result, direct dragging has been established as the standard way of interaction when supporting drag manipulations for them. However, there are scenarios in which direct dragging is not appropriate. For example, when the object to be dragged has to move at a fixed speed or performing an animation independent of the actual direct movement speed or trajectory of the user's hand. However, nobody has yet explored the suitability of indirect dragging interaction mechanisms that allow designers to effectively implement these scenarios. This paper evaluates different mechanisms of indirect dragging manipulations (Tap-based, Accelerometer-based and Buttons-based) in order to identify those that could be used by kindergarteners in scenarios where the direct dragging is not suitable. The results show that even though kindergarten children are able to effectively use different types of indirect dragging techniques, some considerations in terms of completion time and precision must be taken into account.

Interaction with handheld devices is usually limited to multi-touch input in the small display area and does not consider the space above and around the surfaces. In this paper we present and evaluate a way of exploiting this 3D space by enabling precise mid-air interactions using fiducial markers to create multi-display educational games that foster collaboration and physical mobility. Our evaluation determines that sixty children aged 6 to 12 years can effectively perform precise mid-air manipulations with these markers and reports their positive impressions of this type of interaction.

Entertainment technology increases children’s engagement in educational activities designed to develop abilities ranging from collaborative problem-solving and cognitive attention to self-esteem. However, little research has been done on designing educational and entertaining interactive technology for kindergarten children (up to 5 years old). Furthermore, most of the work in this area has considered traditional input devices such as the mouse and keyboard, which are not suitable for these very young children. More recently, other more intuitive means of interaction (touch and tangible interfaces) and advanced educational artifacts such as robots have emerged. In this work we therefore present a joint collaboration between technologists and kindergarten instructors to design and evaluate a technological platform using a mobile robot for kindergarten instruction, as well as an intuitive and user-friendly tangible user interface. The results obtained suggest the platform is not only usable by kindergarten children, but it also allows them to be fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In addition, the instructors reported that the system was well accepted and praised its versatility in use as a supporting tool for their everyday classroom activities., This work is funded by the European Development Regional Fund (EDRF-FEDER) and supported by Spanish Ministry of Economy and Competitiveness with Project TIN2014-60077-R, and from Universitat Politècnica de València under Project UPV-FE-2014-24.

International audience; The direct manipulation interaction style of multi-touch technology makes it ideal for pre-kindergarten children. Recent studies have shown that these challenging users are able to perform a set of basic multi-touch gestures. However, little is known about the accuracy that they can achieve. This paper evaluates the performance of pre-kindergarten children when accuracy is required in the termination phase of these gestures and points out that a mechanism for dynamically adapting the accuracy level could help children in their motor skills development.

The direct manipulation interaction style of multi-touch technology makes it the ideal mechanism for learning activities from pre-kindergarteners to adolescents. However, most commercial prekindergarten applications only support tap and drag operations. This paper investigates pre-kindergarteners' (2–3 years of age) ability to perform other gestures on multi-touch surfaces. We found that these infants could effectively perform additional gestures, such as one-finger rotation and two-finger scale up and down, just as well as basic gestures, despite gender and age differences. We also identified cognitive and precision issues that may have an impact on the performance and feasibility of several types of interaction (double tap, long press, scale down and two-finger rotation) and propose a set of design guidelines to mitigate the associated problems and help designers envision effective interaction mechanisms for this challenging age range. & 2014 Elsevier Ltd.

Pre-kindergarten children are becoming frequent users of multi-touch technology and, according to previous studies they are able to perform several multi-touch gestures successfully. However, they do not use these devices supervised at all times. Consequently, interactive applications for pre-kindergarteners need to convey their underlying design intent and interactive principles with respect to touch interaction. In this paper, we present and evaluate two approaches to communicate three different touch gestures (tap, drag and scale up) to pre-kindergarten users. Our results show, firstly, that it is possible to effectively communicate them using visual cues and, secondly, that an animated semiotic approach is better than an iconic one., Work supported by the MINECO (grant TIN2010-20488) and GVA VALi+d program (grant APOSTD/2013/013).

Multi-touch technology provides users with a more intuitive way of interaction. However, pre-kindergarten children, a growing group of potential users, have problems with some basic gestures according to previous studies. This is particularly the case of the double tap and long pressed gestures, which have some issues related to spurious entry events and time-constrained interactions, respectively. In this paper, we empirically test specific strategies to deal with these issues by evaluating off-the-shelf implementations of these gestures against alternative implementations that follow these guidelines. The study shows that the implementation of these design guidelines has a positive effect on success rates of these two gestures, being feasible their inclusion in future multi-touch applications targeted at pre-kindergarten children., This work received financial support from the Spanish Ministry of Education under the National Strategic Program of Research and Projects TIN2010-20488 (CREATEWORLD) and TIN2012-34003 (insPIre).
