Gestures and Interaction: exploiting natural abilities in the design of interactive systems
Collana seminari interni 2012, Number 20120606.This talk explores the role of gestures in computer supported collaboration. People make extensive use of non-verbal forms of communication when they interact with each other in everyday life: of these, gestures are relatively easy to observe and quantify. However, the role of gestures in human computer interaction so far has been focused mainly on using conventional signs like visible commands, rather than on exploiting all nuances of such natural human skill. We propose a perspective on natural interaction that builds on recent advances in tangible interaction, embodiment and computer supported collaborative work. We consider the social and cognitive aspects of gestures and manipulations to support our claim of a primacy of tangible and multi-touch interfaces, and describe our experiences focused on assessing the suitability of such interface paradigms to traditional application scenarios
Gestures and cooperation: considering non verbal communication in the design of interactive spaces
This dissertation explores the role of gestures in computer supported collaboration. People make extensive use of non-verbal forms of communication when they interact with each other in everyday life: of these, gestures are relatively easy to observe and quantify. However, the role of gestures in human computer interaction so far has been focused mainly on using conventional signs like visible commands, rather than on exploiting all nuances of such natural human skill. We propose a perspective on natural interaction that builds on recent advances in tangible interaction, embodiment and computer supported collaborative work. We consider the social and cognitive aspects of gestures and manipulations to support our claim of a primacy of tangible and multi-touch interfaces, and describe our experiences focused on assessing the suitability of such interface paradigms to traditional application scenarios. We describe our design and prototype of an interactive space for group-work, in which natural interfaces, such as tangible user interfaces and multi-touch screens, are deployed so as to foster and encourage collaboration. We show that these interfaces can lead to an improvement in performances and that such improvements appear related to an increase of the gestures performed by the users. We also describe the progress on the state of the art that have been necessary to implement such tools on commodity hardware and deploy them in a relatively uncontrolled environment. Finally, we discuss our findings and frame them in the broader context of embodied interaction, drawing useful implications for interactions design, with emphasis on how to enhance the activity of people in their workplace, home, school, etc. supported in their individual and collaborative tasks by natural interfaces
Interactive Spaces Natural interfaces supporting gestures and manipulations in interactive spaces
This doctoral dissertation focuses on the development of interactive spaces through the use of
natural interfaces based on gestures and manipulative actions. In the real world people use their
senses to perceive the external environment and they use manipulations and gestures to
explore the world around them, communicate and interact with other individuals. From this
perspective the use of natural interfaces that exploit the human sensorial and explorative
abilities helps filling the gap between physical and digital world.
In the first part of this thesis we describe the work made for improving interfaces and devices for
tangible, multi touch and free hand interactions. The idea is to design devices able to work also
in uncontrolled environments, and in situations where control is mostly of the physical type
where even the less experienced users can express their manipulative exploration and gesture
communication abilities.
We also analyze how it can be possible to mix these techniques to create an interactive space,
specifically designed for teamwork where the natural interfaces are distributed in order to
encourage collaboration.
We then give some examples of how these interactive scenarios can host various types of
applications facilitating, for instance, the exploration of 3D models, the enjoyment of multimedia
contents and social interaction.
Finally we discuss our results and put them in a wider context, focusing our attention particularly
on how the proposed interfaces actually improve people’s lives and activities and the interactive
spaces become a place of aggregation where we can pursue objectives that are both personal
and shared with others

Multitouch sensing for collaborative interactive walls
In this paper we explain the design of t-Frame, a hardware/software architecture that allows the implementation of multiuser interactive wall. t-Frame brings multi-touch sensing to a generic display by means of low cost digital video cameras. The design of t-Frame is illustrated in detail, together with a prototype installation. We show how t-Frame differs from other approaches and discuss our findings, together with a plan of future research and improvements.</p
