“…[10,32]), but also early on in HCI [23] wherein RT has become a frequent measure of interaction technique performance (see e.g. [13,17,22,25] for recent examples). Interaction interferences involve a specific type of reaction time, sometimes called "Stop-Signal Reaction Time" (SSRT), in which the stimulus calls for an absence of reaction, or for the inhibition of an already planned reaction.…”

We study interaction interferences, situations where an unexpected change occurs in an interface immediately before the user performs an action, causing the corresponding input to be misinterpreted by the system. For example, a user tries to select an item in a list, but the list is automatically updated immediately before the click, causing the wrong item to be selected. First, we formally define interaction interferences and discuss their causes from behavioral and system-design perspectives. Then, we report the results of a survey examining users' perceptions of the frequency, frustration, and severity of interaction interferences. We also report a controlled exper iment, based on state-of-the-art experimental protocols from neuroscience, that explores the minimum time interval, before clicking, below which participants could not refrain from com pleting their action. Finally, we discuss our findings and their implications for system design, paving the way for future work.

“…However, as a rehearsal-based technique, FastTap uses a delay before displaying the menu. Delay not only can increase error rate [32,46] but also its necessity has been questioned in the context of Marking Menus [32]. On the other hand, SoftCuts is a delay-less technique that relies on a keyboard layout, a spatially consistent interface.…”

We advocate for the usage of hotkeys on touch-based devices by capitalising on soft keyboards through four studies. First, we evaluated visual designs and recommended icons with command names for novices while letters with command names for experts. Second, we investigated the discoverability by asking crowdworkers to use our prototype, with some tasks only doable upon successfully discovering the technique. Discovery rates were high regardless of conditions that vary the familiarity and saliency of modifier keys. However, familiarity with desktop hotkeys boosted discoverability. Our third study focused on how prior knowledge of hotkeys could be leveraged and resulted in a 5% selection time improvement and identified the role of spatial memory in retention. Finally, we compared our soft keyboard layout with a grid layout similar to FastTap. The latter offered a 12–16% gain on selection speed, but at a high cost in terms of screen estate and low spatial stability.

“…It offers both novice and expert modes of interaction, where for the latter, the menu only gets displayed after a delay. However, several studies have suggested that users have difficulties to adopt the expert mode [18,29] and a recent study also investigated the necessity of the delay-based appearance [21] of Marking Menus, hence raising similar questions for existing techniques, such as FastTap.…”

Touch-based devices, despite their mainstream availability, do not support a unified and efficient command selection mechanism, available on every platform and application. We advocate that hotkeys, conventionally used as a shortcut mechanism on desktop computers, could be generalized as a command selection mechanism for touch-based devices, even for keyboard-less applications. In this paper, we investigate the performance and usage of soft keyboard shortcuts or hotkeys (abbreviated SoftCuts) through two studies comparing different input methods across sitting, standing and walking conditions. Our results suggest that SoftCuts not only are appreciated by participants but also support rapid command selection with different devices and hand configurations. We also did not find evidence that walking deters their performance when using the Once input method. CCS CONCEPTS • Human-centered computing → Interaction techniques.
