Real-time embedded systems

by Tianyu Wang, Antonio Corradi, Lorenzo Torresani, Andrew T. Campbell
"... Research in social science has shown that mobile phone conversations distract users, presenting a significant impact to pedestrian safety; for example, a mobile phone user deep in conversation while crossing a street is generally more at risk than other pedestrians not engaged in such behavior. We p ..."

of the WalkSafe App that is capable of real-time detection of the front and back views of cars, indicating cars are approaching or moving away from the user, respectively. WalkSafe is implemented on Android phones and alerts the user of unsafe conditions using sound and vibration from the phone. Walk

Active-Speaker Detection and Localization with Microphones and Cameras Embedded into a Robotic Head

by Jan Cech , Ravi Mittal , Antoine Deleforge , Jordi Sanchez-Riera , Xavier , Alameda-Pineda , Radu Horaud
"... Abstract-In this paper we present a method for detecting and localizing an active speaker, i.e., a speaker that emits a sound, through the fusion between visual reconstruction with a stereoscopic camera pair and sound-source localization with several microphones. Both the cameras and the microphone ..."

describe a realtime implementation using the proposed technique and with a humanoid head embedding four microphones and two cameras: this enables natural human-robot interactive behavior.

SmartCar: Detecting Driver Stress

by Jennifer Healey, Rosalind Picard - In Proceedings of ICPR’00 , 2000
"... Smart physiological sensors embedded in an automobile afford a novel opportunity to capture naturally occurring episodes of driver stress. In a series of ten ninety minute drives on public roads and highways, electrocardiogram, electromyogram, respiration and skin conductance sensors were used ..."

used to measure autonomic nervous system activation. The signals were digitized in real time and stored on the SmartCar's pentium class computer. Each drive followed a prespecified route through fifteen different events, from which four stress level categories were created according

Real-time Street Parking Availability Estimation

by Bo Xu, Ouri Wolfson, Jie Yang, Leon Stenneth, Philip S. Yu, Peter C. Nelson
"... Abstract — Real-time parking availability information is important in urban areas, and if available could reduce congestion, pollution, and gas consumption. In this paper, we present a software solution called PhonePark for detecting the availability of on-street parking spaces. The solution uses th ..."

StressSense: Detecting Stress in Unconstrained Acoustic Environments using Smartphones

by Hong Lu, Denise Frauendorfer, Daniel Gatica-perez, Mashfiqui Rabbi, Marianne Schmid Mast, Gokul T. Chittaranjan, Andrew T. Campbell, Tanzeem Choudhury - In UbiComp ’12. ACM , 2012
"... Stress can have long term adverse effects on individuals’ physical and mental well-being. Changes in the speech production process is one of many physiological changes that happen during stress. Microphones, embedded in mobile phones and carried ubiquitously by people, provide the opportunity to con ..."
Abstract - Cited by 43 (4 self) - Add to MetaCart
Sense classifier can robustly identify stress across multiple individuals in diverse acoustic environments: using model adaptation StressSense achieves 81 % and 76 % accuracy for indoor and outdoor environments, respectively. We show that StressSense can be implemented on commodity Android phones and run in real-time

Sayanti Banerjee et. al. / Indian Journal of Computer Science and Engineering (IJCSE) IMPLEMENTATION OF IMAGE PROCESSING IN REAL TIME CAR PARKING SYSTEM

by Ms. Sayanti Banerjee
"... Car parking lots are an important object class in many traffic and civilian applications. With the problems of increasing urban traffic congestion and the ever increasing shortage of space, these car parking lots are needed to be well equipped with automatic parking Information and Guidance systems. ..."

, and identifying the stalls available. The system detects cars through images instead of using electronic sensors embedded on the floor. A camera is installed at the entry point of the parking lot. It captures image sequences. The image sequences are then analyzed using digital image processing for vehicle

ISMIR 2008 – Session 2b – Music Recognition and Visualization A ROBOT SINGER WITH MUSIC RECOGNITION BASED ON REAL-TIME BEAT TRACKING

by unknown authors
"... A robot that can provide an active and enjoyable user inter-face is one of the most challenging applications for music information processing, because the robot should cope with high-power noises including self voices and motor noises. This paper proposes noise-robust musical beat tracking by using ..."
Abstract - Add to MetaCart
a robot-embedded microphone, and describes its ap-plication to a robot singer with music recognition. The pro-posed beat tracking introduces two key techniques, that is, spectro-temporal pattern matching and echo cancellation. The former realizes robust tempo estimation with a shorter window length

NOISE SOURCE LOCALISATION IN A CAR ENVIRONMENT

by B. Fazenda, Fengshou Gu, Andrew Ball, Luyang Guan
"... Spurious noise (rattles, squeaks, etc) in the interior of car cabinets can be annoying, distractive and indicative of potential performance problems. Fault finding these problems can be difficult since the fault is intermittent and may not necessarily happen under test conditions. A 3 channel system ..."
Abstract - Add to MetaCart
system that can record the fault and indicate its location within the cabinet is presented here. The system consists of a coincident microphone array that measures acoustic particle velocity along two orthogonal axes at its location. Detection and direction of noise can be obtained in real time or during
