Privacy-enhanced Displays by Time-masking Images
This paper describes a method for enhancing the privacy of computer displays in public and semipublic areas. By operating the display at a higher-than-usual frame rate and alternately displaying frames of an arbitrary private image and a computed mask image, unauthorized viewers perceive one image, while authorized viewers with appropriately keyed shutterglasses see an entirely different (and p...
متن کاملVideo Conferencing on Non-Planar Interactive Displays
Several recent publications introduce user interface prototypes with non-planar interactive surfaces. Using our own prototype Curve featuring a large vertically curved interactive surface, we want to explore video conferencing and remote collaboration scenarios on non-planar interactive surfaces. We discuss the factors framing, mobility, conception of space and interface compatibility, which mi...
متن کاملScaled-up Nonequilibrium Air Plasmas
The volume scalability of nonequilibrium plasmas produced by electrical discharges in atmospheric pressure air has been investigated. A variety of direct current (DC) and pulsed glow discharges obtained in either slow flow of ambient or fast flow of preheated (~2000 K) air at atmospheric pressure is presented. Single DC and repetitively pulsed discharges represent the first approach. Stable dis...
متن کاملScaled-down nuclease P1 for scaled-up DNA digestion.
Motivated by an interest in detecting DNA adducts in their nucleotide form by mass spectrometry (1), we sought efficient, low-cost conditions for enzymatic digestion of a relatively large amount of DNA (≥ 1 mg). Of the enzymes available for such digestion, nuclease P1, which forms deoxynucleoside-5′-monophosphates, seemed to be a good initial choice because it is widely used for digesting DNA, ...
متن کاملThe masking-level difference in low-noise noise.
In experiment 1 NoSo and NoS pi thresholds for a 500-Hz pure tone were obtained in a low-fluctuation masking noise and a high-fluctuation masking noise for six normal-hearing listeners. The noise bandwidth was 10 Hz. In agreement with previous investigations, the NoSo thresholds were lower in low-fluctuation noise than in high-fluctuation noise. For three listeners, NoS pi thresholds were simil...
