Multimodal Input-Dependent Object Query Initialization for LiDAR-Camera 3D Object Detection with Transformers

3D object detection models that exploit both LiDAR and camera sensor features are top performers in large-scale autonomous driving benchmarks. A transformer is a popular network architecture used for this task, in which so-called object queries act as candidate objects. Initializing these object queries based on current sensor inputs leads to...

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...

Tracking Sustained Attention with Webcam-Based Eye Gaze and Blink Tracking

Sustained attention is a cognitive state where the learners’ attention is completely focused on the learning environment and content-related thoughts for a continuous stretch of time. Sustained attention is vital to perform well on learning tasks, such as reading. Learning analytics platforms that detect changes in sustained attention can...

Exploring the effects of carbon pricing on the decarbonization of freight transport in the Netherlands

In 2015, the UN climate agreement was signed by the Netherlands, which has the central aim to “strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius” (UNFCCC, 2018)....

Design of a Vibration Energy Harvester based on Coupled Oscillators

Vibration energy harvesting is the solution for powering on-road sensor measurements. Various techniques to harvest the most energy from a certain application are found in literature. An electromagnetic energy harvester was found to be the best option for transport applications. <br/>In this work, the potential benefits of a coupled oscillator...

Investigation of travel behaviour on a multimodal Mobility-as-a-Service hub within a closed user area

Hely has developed Mobility as a Service (MaaS) through multimodal Hubs,<br/>which are offered within closed-user residential areas and made accessible<br/>through an application. This exploratory study aims to assess people’s mobility<br/>behaviour by the usage of Hely in a closed user group. It focused on two<br/>aspects: the indication of (1)...

Layered Regression Analysis on Multimodal Approach for Personality and Job Candidacy Prediction and Explanation

Video blogs (vlogs) are a popular media form for people to present themselves. In case a vlogger would be a job candidate, vlog content can be useful for automatically assessing the candidate's traits, as well as potential interviewability. Using a dataset from the CVPR ChaLearn competition, we build a model predicting Big Five personality trait...

Designing Haptic Graphics for Mathematics: Towards Accessible Math Education for Blind Students

Currently 75% of children with a visual impairment attend regular schools. Schools are digitizing, which poses both advantages as well as threads to the education of students who are blind. With help of VoiceOver or refreshable braille displays, digital textual information has become accessible to the student, however, there is no solution...

Conceptual design of a carrier-pod aircraft configuration

Whether travelling by aircraft, train or roads or a combination thereof, the EU aims to reduce the door-to-door travel time within Europe to approximately four hours overall travel time. This goal is hard to reach, especially when flights already take three hours or more. Since aircraft realistically can’t fly faster without going supersonic or...

A Performance Meaurement System for Schiphol's Traffic & Transportation: Measuring Perceived Landside Accessibility of Multimodal Airports

Introduction Daily approximately 150.000 individual travel movements are conducted by passengers and Schiphol-workers to and from Schiphol. For this they use cars, taxis, busses, shut-tles, trains, motorcycles, scooters and bicycles. As such Schiphol is Holland’s biggest mobility node. Understandably this makes accessibility of vital importance....

Metropolitan informal mobility

A research and design package development of the informal mobility in Bangkok to promote multi modality

Analysis and recording of multimodal data

Emotions are part of our lives. Emotions can enhance the meaning of our communication. However, communication with computers is still done by keyboard and mouse. In this human-computer interaction there is no room for emotions, whereas if we would communicate with machines the way we do in face-to-face communication much information can be...

Midas v1.0: Multimodal Interface for DNA Alignment of Sequences

Major research efforts in Bioinformatics include sequence alignment, gene finding, genome assembly, protein structure alignment, protein structure prediction, prediction of gene expression and protein-protein interactions, and the modeling of evolution. To perform these specific tasks different tools are used. Using these tools separately is a...
