The number of digital devices is already greater than the number of people on the planet. This means most users use multiple digital devices every day, which is bound to have an impact on their daily practices. However, very little research has been conducted on this emerging phenomenon. This research in progress aims to explore the impact of multi digital device usage on practices and producti...

Low power body motion detection is useful for applications including long term monitoring and image registration for internal imaging. In this paper, a linearized inherently digital capacitive tilt sensor is presented, along with progress on MEMS fabrication. The device is designed for full range (–70° to +70°) tilt ang le detection, and to generate linear digital output without analogue-to-dig...

From real spectroradiometric data, we propose an algorithm to obtain camera opto-electronic conversion functions (camera OECFs) for different values of the lens aperture N from the opto-electronic conversion spectral functions (OECSFs). Working in the linear range of the inverse OECFs, we have found that the slope vs. lens aperture function is fitted by a second order polynomial. This happens a...
