      We present SliceView, a simple and inexpensive multi-view display made with multiple parallel translucent sheets that sit on top of a regular monitor; each sheet reflects different 2D images that are perceived cumulatively. ...
    • Experimental evaluation of distortion in amplitude modulation techniques for parametric loudspeakers 

      San Martín Murugarren, Ricardo Upna Orcid; Tello Santacana, Pablo; Valencia Leoz, Ana Upna; Marzo Pérez, Asier Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      Parametric loudspeakers can generate a highly directional beam of sound, having applications in targeted audio delivery. Audible sound modulated into an ultrasonic carrier will get self-demodulated along the highly directive ...
    • Experimental investigation of the particle oscillation instability in a single-axis acoustic levitator 

      Andrade, Marco Aurélio Brizzotti; Polychronopoulos, Spyros; Memoli, Gianluca; Marzo Pérez, Asier Upna Orcid (AIP Publishing, 2019)   Artículo / Artikulua  OpenAccess
      Single-axis acoustic levitators are employed in biomedicine, chemistry and physics experiments due to their ability to trap in mid-air objects of a wide range of materials and sizes. Although this type of levitator has ...
    • Exploring the addition of audio input to wearable punch recognition
