“…For example, Cockburn and McKenzie [2002] showed that users predicted that they would perform poorly in a spatial task but subsequently rated their actual performance much higher. Similarly, studies have consistently shown that keyboard shortcuts offer a higher performance ceiling than does mouse selection [Odell et al 2004;Lane et al 2005;], yet Tak et al [2013] found that some participants did not use known hotkeys because they believed toolbar selections were faster. 9.…”

Interface design guidelines encourage designers to provide high-performance mechanisms for expert users. However, research shows that many expert interface components are seldom used and that there is a tendency for users to persistently fail to adopt faster methods for completing their work. This article summarizes and organizes research relevant to supporting users in making successful transitions to expert levels of performance. First, we provide a brief introduction to the underlying human factors of skill acquisition relevant to interaction with computer systems. We then present our focus, which is a review of the state of the art in user interfaces that promote expertise development. The review of interface research is based around four domains of performance improvement: intramodal improvement that occurs as a factor of repetition and practice with a single method of interaction; intermodal improvement that occurs when users switch from one method to another that has a higher performance ceiling; vocabulary extension, in which the user broadens his or her knowledge of the range of functions available; and task mapping, which examines the ways in which users perform their tasks. The review emphasizes the relationship between interface techniques and the human factors that explain their relative success.

“…Plusieurs travaux ont facilité l'utilisation des raccourcis clavier [3,12,20,29,30,43]. Par exemple, Grossman et al augmentent l'exposition des raccourcis clavier soit en augmentant la saillance des raccourcis clavier, soit en augmentant le coût de la sélectionà la souris [12].…”

Shi ftCtr l = Print Hand on mouseHand off mouse Figure 1: Gauche : CtrlMouse duplique les touches Ctrl et Shift sur la souris pour délimiter l'entrée de texte de la sélection de commandes et réduire le besoin de coordination des doigts de la main gauche. Droite : TouchCtrl déclenche automatiquement la touche Ctrl lorsque l'utilisateur a sa main posée sur la souris. R « ESUM « ELes touches modifieur du clavier comme Ctrl ou Cmd ( ) sont utilisées pour délimiter l'entrée de texte de la sélection de commandes (raccourcis claviers). Dans cet article nousétudions l'impact de la localisation de ces délimiteurs sur la performance et la charge musculaire en les dupliquant sur la souris.À cet effet, nous dérivons deux techniques d'interaction : CtrlMouse duplique les touches Ctrl et Shift en les associant aux boutons de la souris sous le pouce ; TouchCtrl déclenche automatiquement la touche Ctrl lorsque la main est posée sur la souris. Deux expériences en laboratoire révèlent 1) que ces techniques sont d'autant plus adoptées par les utilisateurs que la tâche demande du pointage, 2) le coût temporel des modifieurs sur la sélection de commandes est de 0, 21s, ce qui correspondà 11, 9% du temps d'exécution et 3) le temps d'exécution avec CtrlMouse avec un ou deux modifieurs est similaire. Nous avonségalement déployé ces techniques pour valider de manièreécologique les résultats obtenus lors desévaluations en laboratoire. Enfin, nous présentons différents scénarii applicatifsélaborésà partir de CtrlMouse et TouchCtrl.

“…This may be attributable to the fact that the shortcut is not displayed until the user has already done most of the work for selecting the command with the mouse, so they have no incentive to learn the hotkey. Malacria et al [28] and Tak et al [39] both developed successful systems that provide "feedforward" information about hotkeys when a modifier key (e.g. Ctrl) is held down, displaying hotkey mappings when they are needed rather than after the fact, with both systems increasing hotkey use.…”

“…However, a user's perception of future performance is often unreliable [13]. In the context of command selection, studies have consistently shown that keyboard shortcuts offer a higher performance ceiling than mouse selection [23,32], yet Tak et al found that some participants failed to use known hotkeys because they believed the toolbar buttons to be faster [39].…”

“…However, designers must recognize that the user's performance goal may depend upon the contextfor example, a user browsing the Internet at home may be less concerned with fast command selection than an office worker who carries out the same tasks throughout the day. Interestingly, however, Tak et al [39] found that increased time pressure did not lead to increased hotkey use, suggesting that workload alone is not sufficient to encourage adoption of more efficient methods (reflecting Carroll's paradox).…”

Figure 1. Three snapshots of a skillometer designed to encourage hotkey use. At first (left), the user mostly relies on mouse selections for activating commands. The skillometer indicates that he could save time by using hotkeys, and displays the appropriate hotkey bindings. As he begins to increase his hotkey use (center), the skillometer shows the benefits of the switch, encouraging him to use more hotkeys (right). ABSTRACTApplications typically provide ways for expert users to increase their performance, such as keyboard shortcuts or customization, but these facilities are frequently ignored. To help address this problem, we introduce skillometers -lightweight displays that visualize the benefits available through practicing, adopting a better technique, or switching to a faster mode of interaction. We present a general framework for skillometer design, then discuss the design and implementation of a real-world skillometer intended to increase hotkey use. A controlled experiment shows that our skillometer successfully encourages earlier and faster learning of hotkeys. Finally, we discuss general lessons for future development and deployment of skillometers.
