We present our prototype of Shvil, an Augmented Reality (AR) system for collaborative land navigation. Shvil facilitates path planning and execution by creating a collaborative medium between an overseer (indoor user) and an explorer (outdoor user) using AR and 3D printing techniques. Shvil provides a remote overseer with a physical representation of the(More)
We present <i>PhoneEar</i>, a new approach that enables mobile devices to understand the broadcasted audio and sounds that we hear every day using existing infrastructure. PhoneEar audio streams are embedded with sound-encoded data using nearly inaudible high frequencies. Mobile devices then listen for messages in the sounds around us, taking actions to(More)
We present Flying Frustum, a 3D spatial interface that enables control of semi-autonomous UAVs (Unmanned Aerial Vehicles) using pen interaction on a physical model of the terrain, and that spatially situates the information streaming from the UAVs onto the physical model. Our interface is based on a 3D printout of the terrain, which allows the operator to(More)
The body provides many recognizable landmarks due to the underlying skeletal structure and variations in skin texture, elasticity, and color. The visual and spatial cues of such body landmarks can help in localizing on-body interfaces, guide input on the body, and allow for easy recall of mappings. Our main contribution are SkinMarks, novel skin-worn I/O(More)
We present our prototype of <i>PlanWell</i>, a spatial augmented reality interface that facilitates collaborative field operations. <i>PlanWell</i> allows a central <i>overseer</i> (in a command and control center) and a remote <i>explorer</i> (an outdoor user in the field) to explore and collaborate within a geographical area. <i>PlanWell</i> provides the(More)
SonicData is a technique for broadcasting data to smartphones via audio streams using phone’s built-in microphone. SonicData augments an audio stream in the environment with nearly inaudible high-frequencies, allowing data to be sent to any smartphone in the vicinity using regular speakers and without any need for special hardware and software(More)
In this paper, we propose a digital fabrication pipeline for designing on-body sensors. We discuss the various steps in our envisioned pipeline and present the technical and research challenges that exist at each of the steps. The research and technical challenges span across various areas, including human computer interaction, computer graphics and(More)
