My Hands or my Mouse: Comparing a Tangible and Graphical User Interface using Eye-Tracking Data

Tangible User Interfaces (TUIs) have drawn the interest of HCI and learning communities because of their potential positive impact on the learning experience. In this paper, we describe a preliminary study of a TUI application for training spatial skills of carpenter apprentices. We designed a tangible interface to perform a CAD modelling activity in a way that resembles what apprentices do in ...

Where should I put my hands? Planning hand location in sign languages

This paper describes a corpus-based study addressing the spatial positioning of hands in Italian Sign Language (LIS). The corpus includes LIS sentences extracted from TV news concerning weather forecasting. The results shows that spatial relations depend on contextual and geographical features. These results have been exploited in the implementation of a planning module that generates a sequenc...

"I wash my hands of it!?" – Trends in hand hygiene over the past decades

Hand hygiene is the most important measure to protect against the spread of nosocomial infections. With the development of in vitro und in vivo test methods for evaluation of the effect of hand hygiene, there has been a sharp increase over the past 50 years in the body of knowledge relating to effective methods for removal from the hands or killing and inactivation of pathogens. In 1958 the Ger...

It’s Out of My Hands! Grasping Capacity May Not Influence Perceived Object Size

Linkenauger, Witt, and Proffitt (2011) found that the perceived size of graspable objects was scaled by perceived grasping capacity. However, it is possible that this effect occurred because object size was estimated on the same trial as grasping capacity. This may have led to a conflation of estimates of perceived action capacity and spatial properties. In 5 experiments, we tested Linkenauger ...
