Handheld devices generally provide the facility of text input through keys that are an inconvenient and slow way of input. Digitizing tablets and light pens, on the other hand provide a natural and convenient way of input. There are many online character recognizers for languages based on Roman and Chinese characters but there is no such commercial product for Urdu/Arabic text input. We present...

Spatial Augmented Reality allows the appearance of physical objects to be transformed using projected light. Computer controlled light projection systems have become readily available and cost effective for both commercial and personal use. This chapter explores how large Spatial Augmented Reality systems can be applied to enhanced design mock-ups. Unlike traditional appearance altering techniq...

Housing systems for farrowing sows have changed very little in the past 30 years. At the mid 20th century, two farrowing environments were common – the outdoor hut in a pasture or lot, and an indoor farrowing pen. The farrowing pens were in low-cost buildings and thus the cost per square foot of building space was relatively low compared to today’s buildings. Farrowing sows indoors has proved t...

Results from the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer are reviewed. A number of recurrent transient sources have been detected, while only a few previously unreported sources have been discovered. The ASM light curves show a wide variety of phenomena in general, and, in particular, those of transient sources show a wide range of properties. Examples are used to illustrate th...

SEGES Pig Research Centre tested three different types of supplementary air inlets in a farrowing house to evaluate the effect on the sows’ immediate environment during the summer. The three different types included trough valves, a single ceiling inlet per sow and transverse ceiling inlets in the section. No supplementary air inlets were installed in the control section. The primary parameters...

Anoto pens are a powerful technology for capturing contents written on paper. However, current pens do not support erasing contents. We show how to easily construct refills for Anoto pens that allow users to erase handwritten traces. Moreover, we discuss how to design software solutions that incorporate paper-based erasing as a first-order command. Author

A major problem a visual system faces is how to fit the large intensity variation of natural image streams into the limited dynamic range of its neurons. One of the means to accomplish this is through the use of fast light adaptation of the photoreceptors. In order to investigate this, we measured first time series of natural intensities, and second responses of fly photoreceptors to these time...

Diabetes treatment is associated with different costs depending upon the type of curative approach used. Most of the time, insulin is administered by two main techniques: cartridges and vials. Insulin pens have emerged as alternative devices for insulin administration. In 2009, the consumption of insulin through insulin pens/cartridges in high-income countries is about 90% while in low-income c...

In this paper we present a novel system for tactile actuation in stylus-based musical interactions. The proposed controller aims to support rhythmical musical performance. The system builds on resistive force feedback, which is achieved through a brakeaugmented ball pen stylus on a sticky touch-sensitive surface. Along the device itself, we present musical interaction principles that are enable...

For different tasks, probe tip should be changed in the 3D vision coordinate measuring system and the accurate determination of probe tip center position is critical. A novel and simple approach for calibrating the probe tip center position of the light pen is presented in this paper. Hundreds of images of the light pen with different postures are collected while the probe tip is kept in firm c...
