This exploratory study examines the impact of spatial and communication settings on perceived presence, communication quality, and participants’ willingness to adopt Virtual Reality (VR)-based collaborative music-making in educational settings. The participants comprised music student teachers and practicing secondary school music teachers. Spatial configurations ranged from separate rooms to shar...Show More
Music in Extended Reality (XR) is increasingly present in both academic and industrial research. While XR applications are more prevalent in STEM education, there is growing interest in the use of XR for music education. This study investigates how multi-user XR scenarios affect perceived social presence and flow in music-related tasks, as both dimensions positively correlate with learning satisfa...Show More
This paper explores a lightweight method for numerical simulation of HRTFs based on a hybrid linear-ERB frequency scale applied to the boundary element method. The HRTFs simulated according to our modified approach were evaluated by comparison with HRTFs acoustically measured and simulated using the standard linear scale. The HUTUBS dataset was used to assess differences in magnitude, interaural p...Show More
An approach is presented how to practically determine which head-related transfer function (HRTF) profiles fit best for individuals wearing a bone conduction headphone. Such headphones may be particularly useful for visually impaired people (e.g., for navigation applications) as they do not obstruct the outer ear. Hence, it is still possible to perceive environmental sounds without restraints whil...Show More
In the present study a new recording method to capture the sound radiation of musical instruments for VR applications is developed. One approach is to record the musical instruments from different angles, which in turn represents a part of the radiation. In order to achieve a steady capture of the sound radiation, different configurations of microphone arrays were used. The microphones were arrang...Show More
Our contribution defines a conjunction operator for private stream searching. Private stream searching is a system of cryptographic methods that preserves the confidentiality of the search criteria and the result. The system uses an encrypted filter to conceal the search terms, processes a search without decrypting these terms, and saves the result to an encrypted buffer. Fundamentally, the system...Show More
