Key research themes
1. How can ancient depicted sign language be systematically decoded to reveal cosmological and spiritual meanings embedded in archaeological artifacts?
This research area explores the methodology of interpreting ancient artifacts, such as vessels, petroglyphs, and sculptures, through the lens of a consistent system of depicted signs derived from historically documented gesture languages. It investigates how form, imagery, gesture signs, and positional cues combine to convey complex cosmological narratives—especially concerning concepts of afterlife, spirit essence, and celestial phenomena (e.g., Venus as the Scout star). Understanding this enables scholars to uncover implicit meanings behind ancient iconography, thus offering new insights into prehistoric belief systems and communication methods.
2. What are the current technological and methodological advances in the automatic translation and recognition of ancient and modern sign languages, and how do they inform educational and interactive applications?
This theme focuses on the intersection of computational linguistics, computer vision, and human-computer interaction to translate and animate sign languages, including efforts to build recognition systems for educational purposes and interactive cultural experiences. It addresses challenges unique to signed languages — lack of standardized orthographies, multimodal articulation, and expressive subtleties — and how these impact machine translation, avatar representation, and sign language corpora development. Practical implementations range from pedagogical platforms for sign language learners to museum guides for deaf visitors, contributing to language preservation and accessibility.
3. How do existing linguistic and gestural theories reconcile the relationships and distinctions between sign language, co-speech gestures, and gesture components within sign communication?
This research strand investigates the theoretical and empirical boundaries between linguistic sign forms and gestural components in signed languages, interrogating whether sign language is fundamentally linguistic, gestural, or a hybrid. It engages with the continuum between categorical conventional signs and imagistic gestures, exploring how signers integrate gesture with linguistic elements and how this influences our understanding of language modality, cognitive processing, and language acquisition. The discourse impacts sign language linguistics, cognitive science, and gesture studies.
