Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating them. However, acoustic levitation has required the targets to be enclosed with acoustic elements or had limited manoeuvrability. Here we optimize the phases used(More)
LeviPath is a modular system to levitate objects across 3D paths. It consists of two opposed arrays of transducers that create a standing wave capable of suspending objects in mid-air. To control the standing wave, the system employs a novel algorithm based on combining basic patterns of movement. Our approach allows the control of multiple beads(More)
In this paper several approaches to implement the ISO/IEEE11073 interoperability standard into personal health devices using low-voltage low-power (LV-LP) microcontrollers are proposed. The patterns methodology previously suggested by the authors is followed in all of the approaches which include an 1-process implementation using non-blocking functions,(More)
Marionette is a haptic device designed to explore touch perception limits between real and device induced shapes. Its novelty resides in the support for 2D exploration over a flat surface and multi-finger capabilities. Marionette is able to apply inclination to four fingers with two degrees of freedom while the user moves the device as if it were a mouse.(More)
Traditionally, e-Health solutions were located at the point of care (PoC), while the new ubiquitous user-centered paradigm draws on standard-based personal health devices (PHDs). Such devices place strict constraints on computation and battery efficiency that encouraged the International Organization for Standardization/IEEE11073 (X73) standard for medical(More)
We present JOLED, a mid-air display for interactive physical visualization using Janus objects as physical voxels. The Janus objects have special surfaces that have two or more asymmetric physical properties at different areas. In JOLED, they are levitated in mid-air and controllably rotated to reveal their different physical properties. We made voxels by(More)
Speech is our innate way of communication. However, it has limitation such as being a broadcast process, it has limited reach and it only works in air. Here, we explore the combination of two technologies for realizing natural targeted communication with potential applications in coordination of tasks or private conversations. For detecting words, we(More)
Nowadays it is increasingly common to own multiple devices such as laptops, smartphones or tablets. Distributed User Interfaces (DUS) leverage the simultaneous use of various devices to interact with different applications. However, no previous work has studied the use of DUS for videogames. Videogames are one of the largest industry but have requirements(More)
Mobile Augmented Reality (MAR) is a mature technology mainly owing to optical tracking libraries capable of determining the position and orientation of tangible markers. However, most of the applications employ only one marker or use them inside a limited interaction space. Here, we present two applications that try to go beyond these previous limits.(More)
