We introduce the "Geremin" approach on in-car 2D microgesture recognition, which belongs to the category of electric field sensing techniques detecting the presence of a human hand near a conductive object (...

The LAMDa workshop aims atdiscussing the impact of Dual Reality (DR) and Mixed Reality (MR) on location awareness and other applications in smart environments. Virtual environments - which are an essential part of dual and mixed realities - can be used to create new applications and to enhance already existing applications in the real world. On the other hand, existing sensors in the real world can be used to enhance the virtual world as well. The combination of both worlds can be well illustrated by location-based services, such as location-based advertising.

Local danger warning is an important function of Advanced Driver Assistance Systems (ADAS) to improve the safety of driving. The user interface (the warning presentation) is particularly crucial to a successful danger avoidance. We present a user study investigating various warning presentations using a scenario of emergent road obstacles. Two presentation factors were selected: modality and level of assistance. The modality factor had 4 variants: speech warning, visual and speech warning, visual warning with blinking cue, and visual warning with sound cue. The level of assistance varied between with or without action suggestions (AS). In accordance with the ISO usability model, a total of 6 measurements were derived to assess the effectiveness and efficiency of the warnings and the drivers' satisfaction. Results indicate that the combination of speech and visual modality leads to the best performance as well as the highest satisfaction. In contrast, purely auditory and purely visual modalities were both insufficient for presenting high-priority warnings. AS generally improved the usability of the warnings especially when they were accompanied by supporting information so that drivers could validate the suggestions. Copyright 2010 ACM.

Chroma-based audio features are a well-established tool for analyzing and comparing music data. By identifying spectral components that differ by a musical octave, chroma features show a high degree of invariance to variations in timbre. In this paper, we describe a novel procedure for making chroma features even more robust to changes in timbre and instrumentation while keeping their discriminative power. Our idea is based on the generally accepted observation that the lower mel-frequency cepstral coefficients (MFCCs) are closely related to timbre. Now, instead of keeping the lower coefficients, we discard them and only keep the upper coefficients. Furthermore, using a pitch scale instead of a mel scale allows us to project the remaining coefficients onto the twelve chroma bins. Our systematic experiments show that the resulting chroma features have indeed gained a significant boost towards timbre invariance.

This book constitutes the thoroughly refereed post-workshop proceedings of the 10th International Workshop of the Initiative for the Evaluation of XML Retrieval, INEX 2011, held in Saarbrücken, Germany, in December 2011.
The 33 revised full papers presented were carefully reviewed and selected for presentation at the workshop from 36 submissions. The papers are organized in 5 research tracks on book and social search, Xdata centric, question answering, relevance feedback, and snippet retrieval.
