The Staircase Procedure Toolkit: Psychophysical Detection Threshold Experiments Made Easy
VRST '23: Proceedings of the 29th ACM Symposium on Virtual Reality Software and TechnologyArticle No.: 86, Pages 1–2https://doi.org/10.1145/3611659.3617218We propose a novel open-source software toolkit to support researchers in the domains of human-computer interaction (HCI) and virtual reality (VR) in conducting psychophysical experiments. Our toolkit is designed to work with the widely-used Unity ...

Effect of Hanger Reflex on Detection Thresholds for Hand Redirection during Forearm Rotation
SAP '23: ACM Symposium on Applied Perception 2023Article No.: 6, Pages 1–8https://doi.org/10.1145/3605495.3605792Hand redirection is a technique used in virtual reality (VR) to alter the virtual hand position from the real hand position, enabling extended interaction in VR. This technique capitalizes on the visual system’s dominance over proprioception, whereby ...

Markovian‐based framework for cooperative channel selection in cognitive radio networks
IET Communications (CMU2), Volume 8, Issue 14Pages 2458–2468https://doi.org/10.1049/iet-com.2013.1158The authors propose Markovian‐based spectrum sensing policies in a cognitive radio system that leverages past sensing outcomes of several cooperating secondary users (SUs) to decide which channel (of primary users – PUs) should be sensed by each SU at a ...

Model Independent CFAR Detection Threshold Determination Based on Right-Tail LCDF Estimation
ICECC '12: Proceedings of the 2012 International Conference on Electronics, Communications and ControlPages 824–827The traditional method for detection threshold (DT) in Constant False Alarm Ratio (CFAR) detection, which is based on parameters estimation of assumed global probability density function (GPDF), may suffer remarkable performance loss due to model ...

Adaptive FCME-based threshold setting for energy detectors
CogART '11: Proceedings of the 4th International Conference on Cognitive Radio and Advanced Spectrum ManagementArticle No.: 33, Pages 1–5https://doi.org/10.1145/2093256.2093289The detection threshold setting and noise uncertainty are known to be critical aspects for energy detectors. Adaptive methods for threshold setting outperform non-adaptive methods due to flexibility and robustness. There exists several adaptive ...

CFAR Outlier Detection With Forward Methods
IEEE Transactions on Signal Processing (TSP), Volume 55, Issue 9Pages 4702–4706https://doi.org/10.1109/TSP.2007.896239Separation or classification of signal-present samples from noise-only samples is studied. The false-alarm probability implies how many noise-only samples are wrongly classified as outliers, and typically it should be smaller than some upper limit. The ...

Analysis of functional magnetic resonance images by wavelet decomposition
The use of the wavelet transform to detect differences between sequentially acquired functional magnetic resonance images (fMRIs) is explored. A statistical data model is developed that makes use of the orthogonality and regularity conditions of the ...
