In this study, we propose an application for immersive virtual reality experiences, which integrates three-dimensional (3D) head-mounted displays (HMDs) with a precise indoor position tracking algorithm based on ultrasound. Our method provides a natural virtual reality experience with interaction by precisely matching the physical movements in the real(More)
In this paper, we present a new system for a highly immersive virtual reality experience utilizing head-mounted displays (HMDs) with accurate indoor-position tracking abilities. The system is designed to have six degrees of freedom in the virtual world, which allows users to physically move around in the real world while wearing the wireless system with an(More)
We have recently introduced a new strategy, based on the meccano method [1, 2], to construct a T-spline parameterization of 2D and 3D geometries for the application of iso-geometric analysis [3, 4]. The proposed method only demands a boundary representation of the geometry as input data. The algorithm obtains, as a result, high quality parametric(More)
As mobile users often operate their devices with one enhancing one-handed interaction. In this paper, we present WhichHand, a system that 1) automatically detects which hand is holding a mobile phone and then 2) enhances user interfaces by adapting layouts to left-or right-handed use. For WhichHand, we utilize orientation sensors from a smartphone and a(More)
