Vibrotactile Stimulus Frequency Optimization for the Haptic BCI Prototype
The paper presents results from a psychophysical study conducted to optimize
vibrotactile stimuli delivered to subject finger tips in order to evoke the
somatosensory responses to be utilized next in a haptic brain computer
interface (hBCI) paradigm. We also present the preliminary EEG evoked responses
for the chosen stimulating frequency. The obtained results confirm our
hypothesis that the hBCI paradigm concept is valid and it will allow for rapid
stimuli presentation in order to improve information-transfer-rate (ITR) of the
BCI.Comment: The 6th International Conference on Soft Computing and Intelligent

Towards transparent telepresence
It is proposed that the concept of transparent telepresence can be closely approached through high fidelity technological mediation. It is argued that the matching of the system capabilities to those of the human user will yield a strong sense of immersion and presence at a remote site. Some applications of such a system are noted. The concept is explained and critical system elements are described together with an overview of some of the necessary system specifications
Contributing to VRPN with a new server for haptic devices (ext. version)
This article is an extended version of the poster paper: Cuevas-Rodriguez, M., Gonzalez-Toledo D., Molina-Tanco, L., Reyes-Lecuona A., 2015, November. “Contributing to VRPN with a new server for haptic devices”. In Proceedings of the ACM symposium on Virtual reality software and technology. ACM.http://dx.doi.org/10.1145/2821592.2821639VRPN is a middleware to access Virtual Reality peripherals. VRPN standard distribution supports Geomagic® (formerly Phantom) haptic devices through the now superseded GHOST library. This paper presents VRPN OpenHaptics Server, a contribution to VRPN library that fully reimplements VRPN support of Geomagic Haptic Devices. The implementation is based on the OpenHaptics v3.0 HLAPI layer, which supports all Geomagic Haptic Devices. We present the architecture of the contributed server, a detailed description of the offered API and an analysis of its performance in a set of example scenarios.Universidad de Málaga.
