چکیده

A cost-effective design of an ultrasonic interface to a graphics tablet is accomplished by means of PIC microcontrollers. This paper analyses the design and implementation from requirements capture through high-level design to circuitry. Ultrasonic transducers enable direct placement of the tablet mechanism above an LCD so that the image is viewed as it is created. Results show that the prototype tablet has up to 0.8 mm resolution.

Feedback-driven Acquisition of Artist-generated Images with an Ultrasonic Interface

Though there are a variety of graphics tablets, these do not necessarily allow an artist to interact with the computer as if handling traditional pens and brushes. A study of practising artists indicates that haptic and propriaptic feedback respectively of pen pressure and motion, together with a direct view of the image being created, is required. Flat-screen LCD (Liquid Crystal Display) techn...

Napkin Sketch

This paper describes, Napkin Sketch, a novel 3D sketching interface which attempts to mimic the qualities of conventional sketching medium and tools both in terms of physical properties and interaction experience. A portable tablet PC is used as the sketching platform, and mixed reality techniques are employed to allow 3D sketches to be created on top of a physical napkin. Intuitive manipulatio...

Resonance Ultrasonic Spectroscopy of a Nanofibrous Composite and Studying the Effect of Surface/Interface

Resonances are intrinsic characteristics of an elastic object, which are completely independent of the source of excitation. The appropriate utilization of the information contained within the resonance spectra and the identification of the resonance frequencies of the object can be used as a potent tool for material characterization. In this paper, a new mathematical model for the wave diffrac...

Design of Shadows on the OHP Metaphor-Based Presentation Interface Which Visualizes a Presenter's Actions

We describe the design of shadows of an overhead projector (OHP) metaphor-based presentation interface that visualizes a presenter’s action. Our interface work with graphics tablet devices. It superimposes a pen-shaped shadow based on position, altitude and azimuth of a pen. A presenter can easily point the slide with the shadow. Moreover, an audience can observe the presenter’s actions by the ...

A Translucent Sketchpad for the Virtual TableExploring Motion - based Gesture

The Virtual Table presents stereoscopic graphics to a user in a workbench-like setting. For this device a user interface and new interaction techniques had been developed based on transparent props {a tracked hand-held pen and a pad 12. These props, but in particular the pad, are augmented with 3D graphics from the Virtual Table's display that can serve as a palette for tools and controls as we...
