“…This was repeated 10 times, with 10 randomly selected angles within their range of roll. This roll experiment-and the pitch experiment that is described next-largely followed a procedure from previous work on rotation using multi-finger gestures [25,36].…”

Expressiveness, which we define as the extent to which rich and complex intent can be conveyed through action, is a vital aspect of many human interactions. For instance, paint on canvas is said to be an expressive medium, because it affords the artist the ability to convey multifaceted emotional intent through intricate manipulations of a brush. To date, touch devices have failed to offer users a level of expressiveness in their interactions that rivals that experienced by the painter and those completing other skilled physical tasks. We investigate how data about hand movementprovided by a motion sensor, similar to those found in many smart watches or fitness trackers -can be used to expand the expressiveness of touch interactions. We begin by introducing a conceptual model that formalizes a design space of possible expressive touch interactions. We then describe and evaluate Expressy, an approach that uses a wrist-worn inertial measurement unit to detect and classify qualities of touch interaction that extend beyond those offered by today's typical sensing hardware. We conclude by describing a number of sample applications, which demonstrate the enhanced expressive interaction capabilities made possible by Expressy.

“…Another important factor for rotation is the initial orientation of targets which can affect the user's performance [8]. We therefore investigate this context in our third experiment, where users perform unimanual rotation gestures.…”

Abstract. Direct touch input is employed on many devices, but it is inherently restricted to displays that are reachable by the user. Gaze input as a mediator can extend touch to remote displays -using gaze for remote selection, and touch for local manipulation -but at what cost and benefit? In this paper, we investigate the potential trade-off with four experiments that empirically compare remote Gaze+touch to standard touch. Our experiments investigate dragging, rotation, and scaling tasks. Results indicate that Gaze+touch is, compared to touch, 1) equally fast and more accurate for rotation and scaling, 2) slower and less accurate for dragging, and 3) enables selection of smaller targets. Our participants confirm this trend, and are positive about the relaxed finger placement of Gaze+touch. Our experiments provide detailed performance characteristics to consider for the design of Gaze+touch interaction of remote displays. We further discuss insights into strengths and drawbacks in contrast to direct touch.

“…A common approach in user-centered gesture design is to enable the user to design gestures for specific predefined commands (Bhandari and Lim 2008;Kray et al 2010;Wobbrock et al 2009). Whilst other researchers have investigated ergonomics in gesture interaction to better understand why certain gestures are easier to perform than others (Hoggan et al 2013;Wobbrock et al 2008), with a goal to develop design recommendations for easier performable gestures.…”

The information that is recordable with touch-sensitive surfaces (the mainstream technology to detect touch) is triggered by skin contact with the surface and contains position data.…”
