Real-time locomotion control by sensing gloves

Abstract Sensing gloves are often used as an input device for virtual 3D games. We propose a new method to control characters such as humans or animals in real-time by using sensing gloves. Based on existing motion data of the body, a new method to map the hand motion of the user to the locomotion of 3D characters in real-time is proposed. The method was applied to control locomotion of characters such as humans or dogs. Various motions such as trotting, running, hopping, and turning could be produced. As the computational cost needed for our method is low, the response of the system is short enough to satisfy the real-time requirements that are essential to be used for games. Using our method, users can directly control their characters intuitively and precisely than previous controlling devices such as mouse, keyboards or joysticks.

Isolation and structural characterization of the Ndh complex from mesophyll and bundle sheath chloroplasts of Zea mays

FEBS JOURNAL, Issue 11 2005
Costel C. Darie
Complex I (NADH: ubiquinone oxidoreductase) is the first complex in the respiratory electron transport chain. Homologs of this complex exist in bacteria, mitochondria and chloroplasts. The minimal complex I from mitochondria and bacteria contains 14 different subunits grouped into three modules: membrane, connecting, and soluble subcomplexes. The complex I homolog (NADH dehydrogenase or Ndh complex) from chloroplasts from higher plants contains genes for two out of three modules: the membrane and connecting subcomplexes. However, there is not much information about the existence of the soluble subcomplex (which is the electron input device in bacterial complex I) in the composition of the Ndh complex. Furthermore, there are contrasting reports regarding the subunit composition of the Ndh complex and its molecular mass. By using blue native (BN)/PAGE and Tricine/PAGE or colorless-native (CN)/PAGE, BN/PAGE and Tricine/PAGE, combined with mass spectrometry, we attempted to obtain more information about the plastidal Ndh complex from maize (Zea mays). Using antibodies, we detected the expression of a new ndh gene (ndhE) in mesophyll (MS) and bundle sheath (BS) chloroplasts and in ethioplasts (ET). We determined the molecular mass of the Ndh complex (550 kDa) and observed that it splits into a 300 kDa membrane subcomplex (containing NdhE) and a 250 kDa subcomplex (containing NdhH, -J and -K). The Ndh complex forms dimers at 1000,1100 kDa in both MS and BS chloroplasts. Native/PAGE of the MS and BS chloroplasts allowed us to determine that the Ndh complex contains at least 14 different subunits. The native gel electrophoresis, western blotting and mass spectrometry allowed us to identify five of the Ndh subunits. We also provide a method that allows the purification of large amounts of Ndh complex for further structural, as well as functional studies. [source]


Organic Electronic Interface Devices: Light- and Touch-Point Localization using Flexible Large Area Organic Photodiodes and Elastomer Waveguides (Adv. Mater.

ADVANCED MATERIALS, Issue 34 2009
34/2009)
The inside cover shows a flexible, large-area, position-sensitive organic photodetector used as an input device for a desktop computer. R. Koeppe et al. show the assembly of such a device with a photodiode based on a blend of Zn-phthalocyanine and C60 with low conductivity electrodes on p. 3510. The current drop across the electrodes easily allows for the calculation of the position of a localized light signal impinging on the position-sensitive photodetector. By adding an additional elastomer layer with embedded LEDs, the device can also be used as flexible touchpad. [source]

Optimum measurability factors in process analytical chromatography
Abstract The theory concerning optimum separation conditions with respect to the precision and minimum peak estimation error is extended with the derivation of the conditions for optimum measurability in case of chemical process control, resulting in extremely short columns to be used. High-speed correlation chromatography (CC) with a special input device is suggested as a solution for the practical problems of these required columns. An example of a one-second correlogram with a spark modulation input device is shown. An alternative is monitoring chemical processes by multiple input chromatography, applying a polynomial fit procedure. Copyright © 2009 John Wiley & Sons, Ltd. [source]


The role and design of screen images in software documentation

JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 4 2000
H. Van der Meij
Abstract, Software documentation for the novice user typically must try to achieve at least three goals: to support basic knowledge and skills development; to prevent or support the handling of mistakes, and to support the joint handling of manual, input device and screen. This paper concentrates on the latter goal. Novice users often experience split-attention problem due to the need to (almost) simultaneously attend to different media. Existing research indicates that split-attention problems can be prevented or reduced by the presence of screen images in the manual. Research is yet unclear about the optimal design of these pictures. This study examines three design styles. Forty-eight novice users received one of the three manual based on these styles. The manuals were an introduction to Windows 95. The users of the most successful manual needed 25% less training time and had a 60% better retention. The most important characteristics of the design style of this manual were its use of full screen images (instead of partial ones) and a two-column lay-out in which the instructions and screen images were presented side-by-side in a left-to-right reading order. The discussion focuses on the tension that exists between theory and practice. Special attention is given to the contributions of a taxonomy of screen images and cognitive load theory. [source]
