Gaze-Hand Steering for Travel and Multitasking in Virtual Environments
Mona Zavichi, André Santos, Catarina Moreira +2
As head-mounted displays (HMDs) with eye-tracking become increasingly accessible, the need for effective gaze-based interfaces in virtual reality (VR) grows. Traditional gaze- or h…
PROMPTHEUS: A Human-Centered Pipeline to Streamline SLRs with LLMs
João Pedro Fernandes Torres, Catherine Mulligan, Joaquim Jorge +1
The growing volume of academic publications poses significant challenges for researchers conducting timely and accurate Systematic Literature Reviews, particularly in fast-evolving…
DALL-M: Context-Aware Clinical Data Augmentation with LLMs
Chihcheng Hsieh, Catarina Moreira, Isabel Blanco Nobre +5
X-ray images are vital in medical diagnostics, but their effectiveness is limited without clinical context. Radiologists often find chest X-rays insufficient for diagnosing underly…
Pseudo-Haptics Survey: Human-Computer Interaction in Extended Reality & Teleoperation
Rui Xavier, José Luís Silva, Rodrigo Ventura +1
Pseudo-haptic techniques are becoming increasingly popular in human-computer interaction. They replicate haptic sensations by leveraging primarily visual feedback rather than mecha…
SPARC: Shared Perspective with Avatar Distortion for Remote Collaboration in VR
João Simões, Anderson Maciel, Catarina Moreira +1
Telepresence VR systems allow for face-to-face communication, promoting the feeling of presence and understanding of nonverbal cues. However, when discussing virtual 3D objects, li…
Integrating Eye-Gaze Data into CXR DL Approaches: A Preliminary study
André Luís, Chihcheng Hsieh, Isabel Blanco Nobre +4
This paper proposes a novel multimodal DL architecture incorporating medical images and eye-tracking data for abnormality detection in chest x-rays. Our results show that applying…
MDF-Net for abnormality detection by fusing X-rays with clinical data
Chihcheng Hsieh, Isabel Blanco Nobre, Sandra Costa Sousa +5
This study investigates the effects of including patients' clinical information on the performance of deep learning (DL) classifiers for disease location in chest X-ray images. Alt…
Development of an Immersive Virtual Colonoscopy Viewer for Colon Growths Diagnosis
João Serras, Anderson Maciel, Soraia Paulo +4
Desktop-based virtual colonoscopy has been proven to be an asset in the identification of colon anomalies. The process is accurate, although time-consuming. The use of immersive in…
Benchmarking Instance-Centric Counterfactual Algorithms for XAI: From White Box to Black Box
Catarina Moreira, Yu-Liang Chou, Chihcheng Hsieh +3
This study investigates the impact of machine learning models on the generation of counterfactual explanations by conducting a benchmark evaluation over three different types of mo…
Hatching for 3D prints: line-based halftoning for dual extrusion fused deposition modeling
Tim Kuipers, Willemijn Elkhuizen, Jouke Verlinden +1
This work presents a halftoning technique to manufacture 3D objects with the appearance of continuous grayscale imagery for Fused Deposition Modeling (FDM) printers. While droplet-…
