miMic: The microphone as a pencil
miMic, a sonic analogue of paper and pencil is proposed: An augmented microphone for vocal and gestural sonic sketching. Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control. The physical device is based on a modified microphone, with embedded inertial sensors and buttons. Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control. With miMic, the sound designer can explore a vast sonic space and quickly produce expressive sonic sketches, which may be turned into sound prototypes by further adjustment of model parameters
Acoustic localization of tactile interactions for the development of novel tangible interfaces
In this paper we propose different acoustic array processing methods for the localization of tactile interactions with planar surfaces. The aim is to create a new class of tangible interfaces for musical performance that can be obtained by simply applying sensors on existing surfaces. The solutions considered in this paper are mainly based on the measurement and the analysis of the Time-Delay-Of-Arrival (TDOA) over a set of contact sensors, placed around the area of potential contact, and allows us to rapidly localize tactile interactions with reasonable accuracy
Mid-Air Haptics for Control Interfaces
Control interfaces and interactions based on touch-less gesture tracking devices have become a prevalent research topic in both industry and academia. Touch-less devices offer a unique interaction immediateness that makes them ideal for applications where direct contact with a physical controller is not desirable. On the other hand, these controllers inherently lack active or passive haptic feedback to inform users about the results of their interaction. Mid-air haptic interfaces, such as those using focused ultrasound waves, can close the feedback loop and provide new tools for the design of touch-less, un-instrumented control interactions. The goal of this workshop is to bring together the growing mid-air haptic research community to identify and discuss future challenges in control interfaces and their application in AR/VR, automotive, music, robotics and teleoperation
Representation of Samba dance gestures, using a multi-modal analysis approach
In this paper we propose an approach for the
representation of dance gestures in Samba dance. This
representation is based on a video analysis of body
movements, carried out from the viewpoint of the
musical meter. Our method provides the periods, a
measure of energy and a visual representation of
periodic movement in dance. The method is applied to
a limited universe of Samba dances and music, which
is used to illustrate the usefulness of the approach
