“…We used the same 4 DIRECTIONs as in Event 1 . We introduced an additional factor, FINGERCOUNT, to capture the two different manipulation styles described in [9]: once a token has been identified with the 3-finger hold, users can keep manipulating it with 3 fingers, or they can relax their grasp and manipulate the token with only 2 fingers. Thus, we had 2 FINGERCOUNT conditions: participants either had to keep their 3 fingers in contact with the surface all along (3-finger condition), or they were asked to lift a finger off the surface after having put the token on the black cross, and to keep it lifted until the end of the trial (2-finger condition).…”

TouchTokens are passive tokens that can be recognized on any capacitive surface based on the spatial configuration of the fingers that hold them. However, interaction with these tokens is confined to the basic two-state model of touch interaction as the system only knows the tokens' position and cannot detect tokens that are not touched. We increase the expressive power of TouchTokens by introducing laser-cut lattice hinges in their design, so as to make them flexible. A new recognizer, that analyzes the micro-movements of the fingers that hold the tokens, enables the system to detect when a token is left on the surface rather than taken off it. It can also detect bend events that can be mapped to command triggers, and a squeezed state that can be used for quasi-modal interaction.

Multitouch interaction with spreadsheets on mobile devices raises multiple interaction issues. In this paper, we present the design and evaluation of novel interaction techniques for spreadsheet based on the stacking paradigm, which consists in laying one edge/face/corner of a smartphone on a tablet screen. We first explore the available gestures and degrees of freedom of our prototype to delimitate the possible interaction's vocabulary. Then, we propose novel interaction techniques to perform range selection in a spreadsheet on a tablet. To detect the smartphone on the tablet screen, we conceive a conductive smartphone copper-shell. We evaluate our prototype against the regular tactile interactions provided by spreadsheet apps. Our studies reveal that some of our interaction techniques perform between 15% and 20% faster for range selection.

RÉSUMÉL'interaction multitouch avec des tableurs sur tablettes soulève de nombreuses problématiques d'interaction. Dans cet article, nous présentons la conception et l'évaluation de nouvelles techniques d'interaction pour tableurs basées sur une manipulation de type stacking, qui consiste à poser l'arête/le coin/la face d'un smartphone sur l'écran d'une tablette. Dans un premier temps, nous explorons l'espace des gestes et les degrés de libertés du stacking afin de délimiter le vocabulaire d'interaction possible. Ensuite, nous proposons plusieurs techniques d'interaction pour réaliser la tâche de sélection de plages de données dans un tableur sur tablette. Afin d'implémenter la détection du smartphone par l'écran de la tablette, nous construisons une coque conductive en cuivre. En utilisant notre prototype nous comparons nos techniques à l'interaction tactile classique proposée par les tableurs. Nos résultats montrent que certaines de nos techniques d'interaction sont entre 15% et 20% plus rapides que le tactile pour sélectionner une plage de données.

TouchTokens were introduced recently as a means to design lowcost tangible interfaces. The technique consists in recognizing multitouch patterns associated with specific tokens, and works on any touch-sensitive surface, with passive tokens that can be made out of any material. TouchTokens have so far been limited to a few basic geometrical shapes only, which puts a significant practical limit to how tailored token sets can be. In this article, we introduce TouchTokenBuilder and TouchTokenTracker that, taken together, aim at facilitating the development of tailor-made tangible interfaces. TouchTokenBuilder is an application that assists interface designers in creating token sets using a simple direct-manipulation interface. TouchTokenTracker is a library that enables tracking the tokens' full geometry. We report on experiments with those tools, showing the strengths and limitations of tangible interfaces with passive tokens.
