Abstract [en]

Multitouch technology allows the users to use both their hands and multiple fingers to manipulate digital content directly on the screen. This paper attempts to analyze the actual convenience of bimanual and multifinger manipulation on a multitouch display by conducting three observational experiments and studying how a group of volunteers use their hands and fingers when interacting with digital content on a touchscreen surface. In addition, the participants had to fill in a questionnaire where they give some additional insights on how they experienced the use of multitouch-based interface during the experiments. The results suggest that when participants were performing tasks in which they were instructed to manipulate the digital content as fast as they could, a high percentage of them resorted to the use of at least some level of bimanual manipulation of the digital content. However, when participants were told to perform the tasks calmly the big majority of participants decided to move the objects by using only one hand (unimanual). Same-hand multifinger manipulation was also used by a high percentage of participants when moving several objects simultaneously. Nevertheless, in all three experiments the most common way of moving objects across the screen was by dragging them one at a time (sequential move). Finally, in relation to the personal assessment made by the participants, a total of 70% feel that the possibility for engaging in bimanual interaction, that multitouch interface offers, is a clear benefit and advantage over traditional keyboard and mouse. However, 40% of the respondents feel that the use of mouse still is a more effective and natural form of interaction than multitouch technology.
