Toward an intelligent multimodal interface for natural interaction
… are enabling novel approaches to human-computer interaction (HCI) in a wide variety of devices and settings (e.g., the Microsoft® Surface, the Nintendo® Wii, iPhone®, etc.). While many of these devices have been commercially successful, the use of multimodal interaction technology is still not …

Natural Interaction: 3D Modeling in Wearable VR Using a Gesture and Speech Interface
… settings. This thesis explores how multimodal interaction, specifically the combination of hand gestures and voice commands, can support more natural, efficient, and accessible 3D modeling in virtual reality (VR). Built on a custom Unity-based system integrating Meta Quest hand tracking and …

A natural interaction reasoning system for electronic circuit analysis in an educational setting
This thesis presents a sketch-based interaction system that can be used to illustrate the process of reasoning about an electrical circuit in an educational setting. Recognition of hand-drawn shapes is accomplished in a two stage process where strokes are first processed into primitives like lines …

Automatic utterance segmentation in spontaneous speech
… it is desireable to have such systems interact naturally with its users. For such natural interaction to occur, recognition systems must be able to accurately detect when a speaker has finished speaking. This research presents an analysis combining lower and higher level cues to perform the …

Designing AI-driven conversational agents to support older adults’ virtual reality learning and lifelong growth
… Their expectations for AI-driven CAs emphasized natural interaction, context awareness, and appropriate emotional engagement, while maintaining clear professional boundaries. Based on these insights, we offer design recommendations for AI-driven CAs to effectively support older adults’ VR …

Asymmetries of power and competence and implications for AAC: interaction between adults with severe learning disabilities and their care staff.
This study investigates the interaction between adults with learning disabilities and their care staff. Many people with severe learning disabilities have little or no speech; for these individuals, augmentative and alternative communication (AAC) may enhance their communication. However, AAC …

Towards Perceptual Augmentation
… devices, leveraging environmental training and natural tasks, emphasizing multisensory interfaces with sensorimotor feedback, and creating affordances that mimic the natural world. This approach seeks to facilitate perceptual learning through natural interaction with the environment, rather than …

A few days of a robot's life in the human's world : toward incremental individual recognition
… exploring the task of face recognition through natural interaction in an incremental and unsupervised fashion. The goal of this thesis is to advance toward a framework which would allow robots to incrementally "get to know" a set of familiar individuals in a natural and extendable way. This …

The computational face for facial emotion analysis: Computer based emotion analysis from the face
… communication. It is believed that a more natural interaction between humans and machines can be undertaken through the detailed understanding of the different facial expressions which imitate the manner by which humans communicate with each other. In this research, we study the different …

Gaze cues and language in communication
… the primary medium of communication in these interactions, yet despite this co-occurrence of speech and gaze cueing, most experiments have used paradigms without language. Furthermore, previous research has shown that myriad social factors influence behaviour during interactions, yet most …

A multiple optical tracking based approach for enhancing hand-based interaction in virtual reality simulations
Research exploring natural virtual reality interaction has seen significant success in optical tracker-based approaches, enabling users to freely interact using their hands. Optical based trackers can provide users with real-time, high-fidelity virtual hand representations for natural interaction …

Quantitative characterization of multi-variable human ankle mechanical impedance
… torque at the ankle joint, plays a key role in natural interaction of the lower-extremity with the environment. The human ankle is a biomechanically complex joint consisting of three bones with non-intersecting anatomical axes, and its motions under normal motor control and function are …

Telethrone : a situated display using retro-reflection basedmulti-view toward remote collaboration in small dynamic groups
… repeated measures experiment to analyse gaze interactions was undertaken. Results suggest that the remote user is not excluded from triadic poker game-play. Analysis of the multi-view aspect of the system was inconclusive as to whether it shows advantage over a set-up which does not support …
