“…Despite the widespread use of Pointer Acceleration, there is very little literature on how to design effective transfer functions for specific input and output systems such as ultra-walls. The PRISM technique [Frees et al 2007] and its subsequent refinements [König et al 2009;Gallo and Minutolo 2012] are among the very few that have documented their transfer functions. However, they were designed to support implicit absolute-to-relative transfer functions and, as we show later in this paper, this approach does not scale to the high indices of difficulty that users of ultra-walls are exposed to.…”

“…1). Beyond recent work by Casiez et al that provides a general framework but does not address such contexts [Casiez and Roussel 2011;, the only documented calibration methods are those related to PRISM [Frees et al 2007] and its refinements [König et al 2009;Gallo and Minutolo 2012]. These methods, however, were designed to calibrate absolute-to-relative transfer functions for pointing techniques that feature an implicit mode switch between absolute and relative pointing.…”

Ultra-high-resolution wall-sized displays ("ultra-walls") are effective for presenting large datasets, but their size and resolution make traditional pointing techniques inadequate for precision pointing. We study mid-air pointing techniques that can be combined with other, domain-specific interactions. We first explore the limits of existing single-mode remote pointing techniques and demonstrate theoretically that they do not support high-precision pointing on ultra-walls. We then explore solutions to improve mid-air pointing efficiency: a tunable acceleration function and a framework for dual-precision techniques, both with precise tuning guidelines. We designed novel pointing techniques following these guidelines, several of which outperform existing techniques in controlled experiments that involve pointing difficulties never tested prior to this work. We discuss the strengths and weaknesses of our techniques to help interaction designers choose the best technique according to the task and equipment at hand. Finally, we discuss the cognitive mechanisms that affect pointing performance with these techniques.

“…absolute vs. relative), input devices, and Control-Display (CD) gain functions, to different levels of speed and precision. Some require highresolution vision-based instrumentation: the PRISM family of techniques [11,12,20], Hybrid RayToRelative Pointing [37], and Laser+Position [25] used Vicon tracking systems to simulate ray-casting for coarse pointing and relative translations for precise acquisition, with different switching mechanisms. Others were designed to only require everyday devices: ARCPad [22] and ARC-Pad2 [25] allow a coarse absolute and a precise relative modes depending on the characteristics of the user's touch on a smartphone.…”
