Interactive Stroke-Based NPR using Hand Postures on Large Displays
نویسندگان
چکیده
We explore the use of hand postures to interact with stroke-based rendering (SBR) on touch-sensitive large displays. In contrast to traditional WIMP interfaces, we allow people to directly engage with and influence a rendering. Our system allows the creation of new stroke primitives as well as provides mechanisms to distribute and then manipulate them on the canvas. We offer a set of natural mappings from hand postures to rendering parameterizations. The resulting system allows an intuitive exploration of SBR without the need for traditional desktop interfaces.

Comparing Free Hand Menu Techniques for Distant Displays Using Linear, Marking and Finger-Count Menus
Distant displays such as interactive Public Displays (IPD) or Interactive Television (ITV) require new interaction techniques as traditional input devices may be limited or missing in these contexts. Free hand interaction, as sensed with computer vision techniques, presents a promising interaction technique. This paper presents the adaptation of three menu techniques for free hand interaction: ...
متن کاملGrasps Recognition and Evaluation of Stroke Patients for Supporting Rehabilitation Therapy
Stroke survivors often suffer impairments on their wrist and hand. Robot-mediated rehabilitation techniques have been proposed as a way to enhance conventional therapy, based on intensive repeated movements. Amongst the set of activities of daily living, grasping is one of the most recurrent. Our aim is to incorporate the detection of grasps in the machine-mediated rehabilitation framework so t...
متن کاملHand Postures Recognition in Large - Display VR Environments
Large–display environments like Reality Center or Powerwall are recent equipments used in the Virtual Reality (VR) field. In contrast to HMDs or similar displays, they allow several unadorned users to visualize a virtual environment. Bringing interaction possibilities to those displays must not suppress the users’ liberty. Thus, devices like DataGlove, wand or devices based on trackers should b...
متن کاملHands-On Analysis and Illustration: Interactive Exploratory Visualization of Vector Fields
We present techniques to interactively explore representations of 2D vector fields. Through a set of simple hand postures used on large, touch-sensitive displays, our approach allows individuals to customdesign glyphs (arrows, lines, etc.) that best reveal patterns of the underlying dataset. Interactive exploration of vector fields is facilitated through freedom of glyph placement, glyph densit...
متن کاملNPR Lenses: Interactive Tools for Non-Photorealistic Line Drawings
NPR Lenses is an interactive technique for producing expressive non-photorealistic renderings. It provides an intuitive visual interaction tool for illustrators, allowing them to seamlessly apply a large variety of emphasis techniques. Advantages of 3D scene manipulation are combined with the capabilities of viewer-aligned lenses by inserting 2D lens controls into the 3D rendering pipeline. By ...
