Otaduy, "Path Routing Optimization for STM Ultrasound Rendering," in IEEE Transactions on Haptics, vol. 13, no. 1, pp. 45-51, 1 Jan.-March 20201939-1412http://hdl.handle.net/10115/16809Ultrasound transducer arrays are capable of producing tactile sensations on the hand, promising hands-free haptic interaction for virtual environments. However, controlling such an array with respect to reproducing a desired perceived interaction remains a challenging problem. In this work we approach this problem as a dynamic mapping of virtual interactions to existing control metaphors of ultrasound devices, namely, the modulation of focal point positions and intensities over time, a method known as Spatiotemporal Modulation (STM). In particular, we propose an optimization approach that takes into account known perceptual parameters and limitations of the STM method. This results in a set of focal point paths optimized to best reconstruct an arbitrary target pressure field.engAtribución-NoComercial-CompartirIgual 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-sa/4.0/Ultrasoundhapticsspatiotemporal modulationInformáticainfo:eu-repo/semantics/preprint10.1109/TOH.2019.2963647info:eu-repo/semantics/openAccess1203.04 Inteligencia Artificial2201.09 Ultrasonidos
