Abstract: Interactive region coloring techniques as implemented by a computing device are described to provide a user with the tactile experience of coloring in a region with digital paint, while at the same time allowing the user to manually fill the region with digital paint with more apparent skill and precision than they may input. For each of multiple pixels on the digital medium, the system obtains one or both of a distance value that indicates a distance to a nearby point (e.g., the closest point) on an outline on the digital medium and a direction value that indicates a direction to the nearby point on the outline. A manner in which the digital paint is applied to the region (e.g., forces affecting paint flow, dynamically adjusting brush size or position) is determined based on one or both of the distance value and the direction value.

Abstract: According to a first aspect, the invention relates to a device (10) for electrochemically releasing a composition and comprising: one working electrode (30) comprising an electroactive conjugated polymer (40) containing or doped with said composition, a counter electrode (50), and a reference electrode (60). The device (10) is characterized in that it comprises electrical means (95, 100; 320; 165, 180) connected to the working electrode (30) and to the counter electrode (50) for obtaining at said working electrode (30) at least one composition releasing sequence (65) with respect to said reference electrode (60), each composition releasing sequence (65) comprising: a first voltametric pulse (70), followed by a rest period (80) during which no current is able to flow through said working electrode (30), followed by a second voltametric pulse (90), followed by an intermediate period (160) during which no current is able to flow through said working electrode (30).

Abstract: The present invention relates to a method and a device for visualising an image by electrical stimulation of functional parts of a visual system. A method according to the present invention comprises an image provision step for providing an image to be visualised by the visual system, a selection step for selecting, from a phosphene data file comprising a description of phosphenes and the stimuli characteristics needed for obtaining them, a number of most appropriate phosphenes to be generated for visualising the image, so that the image is transferred into a summation of patches of light, and a stimulation step for stimulating functional parts of the visual system so as to generate the selected phosphenes. This way, a pixel based image is converted into a plurality of patches of light. A device for carrying out the method is also described.
