Estimating intentions to speak in social settings: Speaker intention estimation using accelerometer data and non-verbal vocal behaviour

Computers having the ability to estimate intentions to speak can improve human-computer interaction. While plenty of research has been done on next-speaker prediction, they differ from intentions to speak since these rely only on the person themselves. Previous research was done on inferring intentions to speak using accelerometer data with some...

Measuring fall risk of the elderly with IMU sensors by developing a Convolutional Neural Network

The combination of the high number and the consequences of falls in older adults led to the development of fall risk assessments; non-sensor-based and sensor-based. Multiple studies used ML for older adults' fall risk prediction using raw IMU data. This study's objective was to develop a DL algorithm that predicts the fall risk of people living...

Rocking Revisited 1: Rocking of a Singe Cube on a Breakwater Slope

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

A hybrid inertial sensor for measuring absolute displacement

Vibrations can be a limiting factor in systems working with nanometer precision. Inertial sensors are used to measure these vibrations. This thesis presents a hybrid inertial sensor using both a displacement and velocity measurement on a single mass-spring system. The measurements are combined into one output of absolute displacement. A...

Handshake Recognition applied to Wireless Data Exchange in Smartbands

The way people meet each other is usually face to face. Meanwhile, the way people maintain their contacts is mostly through social media. This results in a gap of translating a handshake into a digital connection. Shake-On is a start-up that has come up with an answer by means of a smart bracelet. Their aim is to wirelessly exchange contact...

Altimeter ball: From a concept demonstrator towards a production prototype

In deze thesis is het ontwerpproces van de ’Altimeter bal’ beschreven. Deze bal is bedoeld als speelgoed voor kinderen en behoort na een worp de maximale hoogte van die worp weer te geven. Onderzoek is gedaan naar de manier van hoogtebepaling, het materiaal waarvan de bal gemaakt is en de manier waarop de Altimeter bal met de gebruiker...

A Hybrid Box Trainer for Training of Technical Skills in Laparoendoscopic Single Site Surgery (LESS)

The goal of this thesis is to design a hybrid trainer that can quantitatively measure the LESS performance while investigating the difference between LESS and CLS, finally propose a novel objective assessment tools for future research. A force platform is developed, which measures tissue manipulation force in the range of 0-20N with an accuracy...

How High

Het bachelorproject `How High' heeft als doel het opbouwen en testen van een algoritme waarmee worpen van een telefoon gedetecteerd kunnen worden, en waarmee de bereikte hoogte bepaald kan worden. Dit algoritme dient daarna te worden toegepast in een game voor mobiele telefoons. Voor de detectie kan gebruik gemaakt worden van verschillende...
