“…While designing gesture primitives for touchless interfacesoften referred as a kind of NUI-existing studies associate the same meaning with 'natural' and 'intuitive' (Aigner et al, 2012;Grandhi et al, 2011;Hespanhol et al, 2012;Lee, 2010;Morris, 2012;O'Hara et al, 2013;Vatavu and Zaiti, 2014;Wigdor and Wixon, 2011). The meaning of 'natural' or 'intuitive' (we use these terms interchangeably in this paper) that is adopted by these studies does not go beyond the vernacular definition of instinctive or spontaneous.…”

“…in interactive TVs). Although in some of these scenarios users can use handheld devices, such as smartphones or tablets, touchless gestures relieve users from the burden of interacting with an additional medium between the user and the system (Morris, 2012;O'Hara et al, 2013). However, while the industry is rushing to market 328 Debaleena Chattopadhyay and Davide Bolchini new touchless products (e.g.…”

Elicitation and evaluation studies investigated intuitiveness of touchless gestures but did not operationalize intuitiveness. For example, studies found that users fail to make accurate 3D strokes as interaction commands. But this phenomenon remains unexplained. In this paper, we first explain how making accurate 3D strokes is generally unintuitive, because it exceeds our sensorimotor knowledge. We then introduce motor-intuitive, touchless interaction that uses sensorimotor knowledge by relying on image schemas. Specifically, we propose an interaction primitive-mid-air, directional strokesbased on space schemas up-down and left-right. In a controlled study with large displays, we found that biomechanical factors affected directional strokes. Strokes were efficient (0.2 s) and effective (12.5 • angular error), but affected by directions and length. Our work operationalized intuitive touchless interaction using the continuum of knowledge in intuitive interaction, and demonstrated how user performance of a motor-intuitive, touchless primitive based on sensorimotor knowledge (image schemas) is affected by biomechanical factors. RESEARCH HIGHLIGHTS • We operationalized touchless interaction using the continuum of knowledge. • Users fail to make accurate 3D strokes, because it is an expertise level of knowledge. • Motor-intuitive interactions based on image schemas use sensorimotor knowledge. • We studied a motor-intuitive, touchless primitive: mid-air directional strokes. • Results found mid-air strokes efficient (0.2 s) and effective (12.5 • angular error). • Biomechanical factors affected the user performance of mid-air strokes.

Large screen displays are part of many future visions, such as i- LAND [11] that describes the possible workspace of the future. Research showed that wall-sized screens provide clear benefits for data exploration, collaboration and organizing work in office environments. With the increase of computational power and falling display prices wall-sized screens currently make the step out of research labs and specific settings into office environments and private life. Today, there is no standard set of interaction techniques for interacting with wall-sized displays and it is even unclear if a single mode of input is suitable for all potential applications. In this workshop, we will bring together researchers from academia and industry who work on large screens. Together, we will survey current research directions, review promising interaction techniques, and identify the underlying fundamental research challenges.

The single physical remote control, paired to a media sys tem, is no longer necessarily the only (or indeed primary) mechanism of control, with new input modalities (e.g. ges ture) and mechanisms (e.g. mobile devices) allowing any one to contribute to the input and control. This paper in vestigates the potential for extending single-user interfaces in order to support multi-user use, as a means of utilizing new inputs without having to abandon the familiar interfaces, control management behaviours and mental models that users have established. A survey was conducted investigating ex isting behaviours for managing control in terms of prevalence and acceptability. These behaviours and potential new ones were then incorporated into a multi-user system where man agement of control was virtualized, using mobile devices for input. We found that behaviours derived from existing ones (e.g. passing/taking control) were at worst functionally equiv alent to, and in some cases superior to, managing a single physical remote control. We suggest that sharing single-user TV systems implementing these behaviours offers a viable alternative to concurrent use TV systems.
