See-through circuitry

RT-DSP Using ”See Through”

Engineering educators teaching digital signal processing (DSP) have found that using hands-on exercises for students can smooth the transition from theory to practical real-time DSP. However, before significant learning can begin using such exercises, students must build their confidence in the hardware and software platforms. When using audio signals, a “talk-through” project accomplishes this...

To see and see through graphics - Toward affordance- driven geovisualization

From the technical point of view, it is possible for a developer to embed and visualize as much information as possible in an open-ended virtual geographic environment, meanwhile, allow the user to interactively query and manipulate the information. However, the design and interpretation hitherto is a more or less blind experiment. In order to raise the awareness of this problem, the author rev...

Optical see-through HMD calibration: a stereo method validated with a video see-through system

This paper presents initial results from an ongoing work to calibrate optical see-through head-mounted displays (HMDs). We have developed a method to calibrate stereoscopic optical see-through HMDs based on the 3D alignment of a target in the physical world with a virtual object in user’s view. This is an extension of the Single Point Active Alignment Method (SPAAM) [28] developed for monocular...

Calibrating See-Through Head-Mounted Displays

A basic issue in the development of see-through display systems is obtaining precise calibration for the system in relation to the user. Unlike immersive head-mounted displays (HMDs) where only virtual objects are displayed, even small discrepancies in the location of the virtual images can be dis-orienting. Moreover, any discrepancies in global scaling or distortions of virtual objects impairs...
