We present insights from a gesture elicitation study in the context of interacting with TV, during which 18 participants contributed and rated the execution difficulty and recall likeliness of free-hand gestures for 21 distinct TV tasks. Our study complements previous work on gesture interaction design for the TV set with the first exploration of fine-grained resolution 3-D finger movements and hand pose gestures. We report lower agreement rates (.20) than previous gesture studies and 72.8% recall rate and 15.8% false positive recall, results that are explained by the complexity and variability of unconstrained finger gestures. Nevertheless, we report a large 82% preference for gesture commands versus TV remote controls. We also confirm previous findings, such as people's preferences for related gestures for dichotomous tasks, and we report low agreement rates for abstract tasks, such as "open browser" or "show channels list" in our specific TV scenario. In the end, we contribute a set of design guidelines for practitioners interested in free-hand finger and hand pose gestures for interactive TV scenarios, and we release a dataset of 378 Leap Motion gesture records consisting in finger position, direction, and velocity coordinates for further studies in the community. We see this exploration as a first step toward designing low-effort high-resolution finger gestures and hand poses for lean-back interaction with the TV set.

The system of Freeman et al [14] interprets eight static hand postures and allows to control iTV applications like photo browsing in laid-back situations.…”

Due to recent development of TVs in the direction of highly interactive multimedia platforms, interactive TV (iTV) applications gain popularity. In terms of control possibilities a variety of input modalities have become available, though effects on performance and user experience of different age groups when controlling different iTV applications remain unclear. We present an empirical investigation comparing three input modalities (tablet, freehand gestures, remote) for controlling two iTV applications (Photo Browser, Nutrition Tracker) used by older and younger adults. Results show that all three independent variables had significant influence on performance, while we did not find influence of age or application on user experience. Overall tablet input based on a mirrored TV screen showed the best performance and was preferred by both age groups. Older adults were overall slower and showed a particularly large performance gap with the remote in comparison to younger adults.

Reality-Based Interaction (RBI) [14] theorizes that realistic user interactions (UIs) are effective because they exploit users' pre-existing knowledge about their bodies and objects in the world. Gesture based interaction allows users to relay information to a computer through body movement without physical contact with additional hardware such as a mouse or trackball. However, this interaction style requires the users to interact in a manner that is tailored for the system to recognize with very strict rules for bodily interaction, not toward a gesture space that is more natural for the user. In this paper we propose a natural method of gestural input through a user-defined 3-dimensional space. We conducted two pilot studies to assess the performance and usability of these augmented gestural pointing methods for cursor manipulation as compared to a standard mouse interaction as well as the current standard approach used in gestural input.
