Playing musical instruments such as chordophones, percussions and keyboard types accompany with harmonic interaction of player's hand with the instruments. In this work, we present a novel approach that enables the user to imitate the music playing gestures around mobile devices. In our approach, touch-less gestures, which change magnetic field around the(More)
We present in this paper a signal subspace-based approach for enhancing a noisy signal. This algorithm is based on a principal component analysis (PCA) in which the optimal sub-space selection is provided by a variance of the reconstruction error (VRE) criterion. This choice overcomes many limitations encountered with other selection criteria, like(More)
We present in this paper a subspace approach for enhancing a noisy speech signal. The original algorithm for model identification from which we have derived our method has been used in the field of fault detection and diagnosis. This algorithm is based on principal component analysis in which the optimal subspace selection is provided by a variance of the(More)
— Digital music performance require high degree of interaction using natural, intuitive input controllers that provide fast feedback on user's action. One of the primary considerations of professional artists is a powerful and creative tool that minimizes the number of steps required for the speed-demanding processes. Most of the musical performance(More)
The visuospatial learning of a map on cellphone displays was examined. The spatial knowledge of human participants was assessed after they had learned the relative positions of London Underground stations on a map via passive, marginally active, or active exploration. Following learning, the participants were required to answer questions in relation to the(More)
The theory of around device interaction (ADI) has recently gained a lot of attention in the field of human computer interaction (HCI). As an alternative to the classic data entry methods, such as keypads and touch screens interaction, ADI proposes a touchless user interface that extends beyond the peripheral area of a device. In this paper, we propose a new(More)
This paper presents a system that allows the user to interact by speech with a Radio-Frequency IDentification (RFID) network working in a highly noisy environment. A new dialog framework is proposed in order to give the human operators the ability to communicate with the system in a more natural fashion. This is achieved by the implementation of the(More)
We present in this paper a signal subspace-based approach for enhancing a noisy signal. In our previous works we have developed an algorithm based on principal component analysis (PCA) in which the optimal subspace selection is provided by a variance of the reconstruction error (VRE) criterion. In this work we will improve our previous technique by applying(More)
