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 ...

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 ...

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...

Where are my hands? Influence of limb posture on tactile extinction.

OBJECTIVE Tactile localization on the skin involves both a somatotopic and a postural schema (body-schema) representation. The present study determines the extent to which body posture influences tactile perception in right-brain-damaged patients. METHOD In a first set of experiments, patients were asked to detect single tactile stimulation delivered to their left or right hands or to both ha...
