Vi-Bros is a new interface that simultaneously utilizes two mobile devices, a smartphone and a smartwatch, to provide users with intuitive guidance during indoor navigation. We evaluate the validity of the dual device interaction with the tactile feedback and provide insights for user experience via two experiments; one from a controlled environment and the(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)
The advantages offered by centrifugal microfluidic systems have encouraged its rapid adaptation in the fields of in vitro diagnostics, clinical chemistry, immunoassays, and nucleic acid tests. Centrifugal microfluidic devices are currently used in both clinical and point-of-care settings. Recent studies have shown that this new diagnostic platform could be(More)
