“…Phillips (2003) found that older adults not only performed better on a pointing task with the mouse, but preferred it as well. Murata and Iwase (2006), however, found that for older adults, pointing on a touch screen was faster than mousing.…”

Convertible tablet PCs can use a pen or a mouse for input. The pen is better suited than the mouse for some tasks because of its interaction properties, and research has shown it may ameliorate age-related decrements in performance. This study compared the pen and mouse on a series of realistic tasks for older (55-69) and younger (18-30) adults. Precision tasks were better served by the mouse, while ballistic tasks with strong analogs to real-world actions were served equally well by the pen or the mouse. Older adults were slower than younger adults on both devices, but contrary to the research hypothesis, no benefits were observed specifically for older adults with the pen. This study reinforces findings regarding the importance of task demands when selecting input devices. Younger adults seemed more willing than older adults to embrace the pen.

“…Research with older adults has also extended to pointing devices other than the computer mouse, for instance, pen-based input on tablets and handheld computers [Hourcade and Berkel 2008;McGrenere 2007, 2009], touchscreens on touch-panel interfaces, mobile phones, and surfaces [Murata and Iwase 2005;Nicolau and Jorge 2012;Piper et al 2010], and other input devices (e.g., large rollerballs and touchpads) [Taveira and Choi 2009;Wood et al 2005]. These studies aim to better understand and to characterize the nature of older adults' interactions with pointing devices as a basis for informing the design of novel input devices, software interfaces, and assistive techniques.…”

Point and click interactions using a mouse are an integral part of computer use for current desktop systems. Compared with younger users though, older adults experience greater difficulties performing cursor positioning tasks, and this can present limitations to using a computer easily and effectively. Target expansion is a technique for improving pointing performance where the target grows dynamically as the cursor approaches. This has the advantage that targets conserve screen real estate in their unexpanded state, yet can still provide the benefits of a larger area to click on. This article presents two studies of target expansion with older and younger participants, involving multidirectional point-select tasks with a computer mouse. Study 1 compares static versus expanding targets, and Study 2 compares static targets with three alternative techniques for expansion. Results show that expansion can improve times by up to 14%, and reduce error rates by up to 50%. Additionally, expanding targets are beneficial even when the expansion happens late in the movement, that is, after the cursor has reached the expanded target area or even after it has reached the original target area. The participants' subjective feedback on the target expansion are generally favorable, and this lends further support for the technique.

“…First, the ability to physically touch an object on the screen eliminates the need for intermediate interaction devices that must be learned, such as the mouse or joystick. Eliminating this barrier to interaction makes the process simpler, as demonstrated by Murata and Iwase in a study comparing pointing speed for the mouse and a finger [18]. Second, by mimicking the behavior of real-world interactions, direct manipulation makes use of knowledge so fundamental that it seems instinctual.…”

Intuition is an important yet ill-defined factor when designing effective multi-touch interactions. Throughout the research community, there is a lack of consensus regarding both the nature of intuition and, more importantly, how to systematically incorporate it into the design of multi-touch gestural interactions. To strengthen our understanding of intuition, we surveyed various domains to determine the level of consensus among researchers, commercial developers, and the general public regarding which multi-touch gestures are intuitive, and which of these gestures intuitively lead to which interaction outcomes. We reviewed more than one hundred papers regarding multi-touch interaction, approximately thirty of which contained key findings we report herein. Based on these findings, we have constructed a framework of five factors that determine the intuition of multi-touch interactions, including direct manipulation, physics, feedback, previous knowledge, and physical motion. We further provide both design recommendations for multi-touch developers and an evaluation of research problems which remain due to the limitations of present research regarding these factors. We expect our survey and discussion of intuition will raise awareness of its importance, and lead to the active pursuit of intuitive multi-touch interaction design.
