“…(b) Indirect multi-touch: separate output with display of hand contours (a) Direct multi-touch: input and output space coincide Direct versus indirect input has been studied widely for single-pointer interaction, comparing indirect input devices with direct-touch or pen input (e.g., [20,23]). A recent study is close to ours in spirit, as it focuses on a single in-put technology, here a stylus pen, which is compared for direct and indirect interaction showing that indirect use can perform as well for certain tasks [8].…”

Abstract. Multi-touch input on interactive surfaces has matured as a device for bimanual interaction and invoked widespread research interest. We contribute empirical work on direct versus indirect use multi-touch input, comparing direct input on a tabletop display with an indirect condition where the table is used as input surface to a separate, vertically arranged display surface. Users perform significantly better in the direct condition; however our experiments show that this is primarily the case for pointing with comparatively little difference for dragging tasks. We observe that an indirect input arrangement impacts strongly on the users' fluidity and comfort of 'hovering' movement over the surface, and suggest investigation of techniques that allow users to rest their hands on the surface as default position for interaction.

“…There is some evidence to suggest that joypad input has reduced throughput to mouse input (0.69-0.33x bits/s) [33]. There are no wide surveys yet of touch- screen and mouse throughputs, but some touchscreen studies have suggested equivalent or faster movement times than with a mouse [29,6,10], others that mouse input outperforms touchscreen input when the task requires a single point of contact [15], but also that touchscreens potentially decreased accuracy [27]. In principle, it would be possible to design eye-and hand-tracking systems which are suitable for all of these display types (Tab.…”

Panoramic imagery is viewed daily by thousands of people, and panoramic video imagery is becoming more common. This imagery is viewed on many different devices with different properties, and the effect of these differences on spatio-temporal task performance is yet untested on these imagery. We adapt a novel panoramic video interface and conduct a user study to discover whether display type affects spatio-temporal reasoning task performance across desktop monitor, tablet, and head-mounted displays. We discover that, in our complex reasoning task, HMDs are as effective as desktop displays even if participants felt less capable, but tablets were less effective than desktop displays even though participants felt just as capable. Our results impact virtual tourism, telepresence, and surveillance applications, and so we state the design implications of our results for panoramic imagery systems.

“…Sketching behavior has been already experimentally studied [2] but mainly in collaborative and creative contexts. Also many input devices have been tested on their effectiveness in tracing and path steering navigational tasks and this knowledge has been used for multitude of analyses and comparisons [3][4][5].…”

This short paper is a work-in-progress report on an experimental comparison and evalua tion of users' performance in f our linetracing tasks based on two shapes and performed with three input methods (mouse, stylus, and touch-input). The shapes' properties used in the study created the two classes of shapes: easy and hard to replicate. As expected these two classes had different impact on user's performance in each task tested (tracing, lasso selection, steering through narrow and wide tunnel). The results show tha t participants replicating the shapes using touch-input were the least accurate but were the fastest in comparison to the remaining input methods. The stylus was the least error-prone method and the mouse was the slowest device in drawing tasks (tracing and selection). The differences in error distances between the input methods were less pronounced in steering ta sks but timing data showed that mouse was still the slowest one. While the time of replication did not differ between the two sh apes tested, the differences between the errors participants made were significant for all tasks and input devices, and patterns of these differences were consistent between the shapes. These results confirm predictions from a previous study and show which shapes' properties can make their replication more difficult. T he results can be used to design shapes that are easy to repli cate, e.g., in surface-based gestural interaction.
