SUMMARYContinuous pen pressure can be used to operate multistate widgets such as menus in pen based user interfaces. The number of levels into which the pen pressure space is divided determines the number of states in the multi-state widgets. To increase the optimal number of divisions of the pen pressure space and achieve greater pen pressure usability, we propose a new discretization method which divides the pen pressure space according to a personal pen pressure use profile. We present here four variations of the method: discretization according to personal/aggregation pen pressure use profile with/without visual feedback of uniform level widths and the traditional even discretization method. Two experiments were conducted respectively to investigate pen pressure use profile and to comparatively evaluate the performance of these methods. Results indicate that the subjects performed fastest and with the fewest errors when the pen pressure space was divided according to personal profile with visual feedback of uniform level widths (PU) and performed worst when the pen pressure space was divided evenly. With PU method, the optimal number of divisions of the pen pressure space was 8. Visual feedback of uniform level widths enhanced performance of uneven discretization. The findings of this study have implications for human-oriented pen pressure use in pen pressure based user interface designs. key words: human-computer interaction, pen pressure, discretization method, pen pressure profile, pen-based interfaces

“…They observed that users are used to holding three physical tools (pencil, knife, and syringe) differently, and thus they implemented drawing software in which the user can do three operations (copy, paste, and cut) by changing between three pen tilt angles using a tablet. Oshita [11] developed a pen-based intuitive interface to control a virtual human figure interactively. In this system the tilt of the pen is used to affect the figure's motion.…”

“…Studies on tilt techniques have focused mainly on the tilt of the display or input device (regardless of the angle of the pen) [12], [22], while few studies have paid attention to the tilt of the pen in relation to the screen. Three exceptional studies on pen tilt are [6], [11], [21]. In Ramos et al's study [17], they indicated that the pressure input channel can be coupled to: position if variation in the channel translates to changes in x-y coordinates, e.g., cursor position in the List Menu; angle if it translates to changes in angle or orientation of the cursor, e.g., cursor angle in the Pie Menu; and scale if it translates to changes in size or scale of the cursor, e.g., cursor scale in Bullseye.…”

SUMMARYThree experiments were conducted in this study to investigate the human ability to control pen pressure and pen tilt input, by coupling this control with cursor position, angle and scale. Comparisons between pen pressure input and pen tilt input have been made in the three experiments. Experimental results show that decreasing pressure input resulted in very poor performance and was not a good input technique for any of the three experiments. In "Experiment 1-Coupling to Cursor Position", the tilt input technique performed relatively better than the increasing pressure input technique in terms of time, even though the tilt technique had a slightly higher error rate. In "Experiment 2-Coupling to Cursor Angle", the tilt input performed a little better than the increasing pressure input in terms of time, but the gap between them is not so apparent as Experiment 1. In "Experiment 3-Coupling to Cursor Scale", tilt input performed a little better than increasing pressure input in terms of adjustment time. Based on the results of our experiments, we have inferred several design implications and guidelines. key words: pressure input, tilt input, target selection tasks, pen-based interfaces

“…State 2 solves (1) and (2): the cursor will not be blocked while going through a widget, neither will the concurrent movements of rotating and of leaving the widget be hindered. As to conveying a trend of the movement, we applied the filter used by Oshita in our data [5]. We set the filter's constant to a high value, e.g., 0.8, in order to strongly bias the output values by the most recent data, so that switching from state 3 to state 2 be enough responsive.…”

Abstract. We present a work in progress that investigates the manipulation of virtual rotary knobs using a device with three degreesof-freedom. We draw a brief parallel between handling real knobs in professional sound appliances and interacting with desktop rotary widgets. Then, we present an interaction technique aimed to support a natural mapping, to reduce the activation time, and to enhance the fluidity along the gestures that compose this activity.
