—We present an input method which enables complex hands-free interaction through 3d handwriting recognition. Users can write text in the air as if they were using an imaginary blackboard. Motion sensing is done wirelessly by accelerometers and gyroscopes which are attached to the back of the hand. We propose a two-stage approach for spotting and recognition(More)
We present a wearable input system which enables interaction through 3D handwriting recognition. Users can write text in the air as if they were using an imaginary blackboard. The handwriting gestures are captured wirelessly by motion sensors applying accelerometers and gyroscopes which are attached to the back of the hand. We propose a two-stage approach(More)
Dopamine-derived alkaloids, the tetrahydroisoquinolines (TIQs), are suspected to play a role in the pathogenesis of alcoholism. The present study describes the alcohol induced formation of the S-enantiomer of Tetrahydropapaveroline and Norcoclaurine in the rat brain. These compounds are of special interest since both were found as being intermediates in the(More)
Session-and person-independent recognition of hand and finger gestures is of utmost importance for the practicality of gesture based interfaces. In this paper we evaluate the performance of a wearable gesture recognition system that captures arm, hand, and finger motions by measuring movements of, and muscle activity at the forearm. We fuse the signals of(More)
We present and demonstrate Kinemic Wave, a fully freehand and mobile interaction system, which allows gesture control and text-entry on-the-go. We use wrist-worn inertial sensors which are almost independent of environmental influences. The system is therefore especially suited to interact with smart- and augmented-reality glasses. Simple commands like(More)

AIMS Functional magnetic resonance imaging was used in conjunction with a letter detection task for the study of working memory in 16 normal subjects. Because of movement artifacts, data from only 9 subjects were analysed. METHODS In the activation task, subjects responded by pressing a button whenever any presented letter was the same as the second last(More)
Imaging procedures suitable for diagnosis of cephalopelvic disproportion, such as radiological pelvimetry, computer- or magnetic resonance imaging (MRI) fail to reflect the dynamics of delivery, including deformations of the birth channel as well as of foetal structures. In order to validate findings of imaging procedures in this respect, a method has been(More)
The influence of desaminoocta-pancreozymin (DAO-PZ) was investigated in high and low activity periods by intraperitoneal or intranasal application. DAO-PZ is a CCK-8 derivative in which the N-terminal amino acid (Asp) is exchanged for succinyl acid. A decreasing long lasting effect for 3 to 4 h was always observed in locomotor activity. A food reduction was(More)
