Monitoring the heart rate using PPG signals that is worn on the wrist has the downside that it is susceptible to motion. The device on the wrist moves along with the motions of the arm, consequently creating artifacts in the measurement. There are many signal processing techniques that can remove these artifacts. This thesis discusses one of the...

This bachelor’s thesis discusses the idea and implementation of real-time heart rate monitoring using photo- plethysmography (PPG) signals. PPG signals measured from the wrist are often subjected to distortion and noise. Signal processing techniques that tackle these issues were investigated and implemented. The algo- rithm of choice was JOSS....

In this thesis a model for sound reflections designed which is to be used in an audio-based game for visually impaired people is described. This project is a part of a three-group bachelor graduation project of six peoplein total. The three groups combined create a working game for visually impaired children, meant to be used to train the user’s...

This thesis was made for the Bachelor Graduation Project (Electrical Engineering). The purpose of the project was to design an audio-based game for visually impaired children. In this thesis the gameplay and the graph- ical user interface are designed. We choose to make a simplified dungeon crawler in the programming language Python. We designed...

This thesis describes the design of a sound localization algorithm in audio-based games for visually impaired children. An algorithm was developed to allow real-time audio playback and manipulation, using overlapping audio blocks multiplied by a window function. The audio signal was played through headphones. Multiple sound localization cues are...

To obtain the absolute truth about the performance of a noise reduction method one requires to perform a listening experiment. As listening experiments are often time consuming and expensive there exists a need to replace these experiments by instrumental measures. Consequently, research has provided various instrumental measures which can been...

De verstaanbaarheid van de aanwezigen bij teleconferenties is minder dan bij gesprekken waarbij beide partijen zich in \'e\'en ruimte bevinden, aangezien stoorsignalen net zo goed worden opgenomen en verder de ruimtelijke informatie van de spraak verloren gaat. Een systeem werd ontworpen dat real-time bepaalt uit welke richting iemand spreekt,...

Undesired, human behavior in public environments is an increasing issue in today’s society. The overload of security operators and law enforcement addresses the need for automatic detection of anomalous behavior. The EU-project ADABTS aims to facilitate the protection of EU citizens, property and infrastructure against threats of terrorism,...

To convey messages to the public, public address systems (PA) are installed in buildings and at venues. These messages generally contain important information for the listener. This information has to come across well, i.e. the message should be intelligible. Because the environment, and mainly the background noise, can change over time, it is...
