BACKGROUND Contamination of grains with trichothecene mycotoxins, especially deoxynivalenol (DON), has been an ongoing problem for Canada and many other countries. Mycotoxin contamination creates food safety risks, reduces grain market values, threatens livestock industries, and limits agricultural produce exports. DON is a secondary metabolite produced by(More)
We present the Implicit Fan Cursor (IFC) - a novel target pointing technique using a cursor with a fan-shape activation area. The IFC couples the cursor's activation area with its velocity, i.e., the speed and direction of the mouse motion, behaving like a 2D spotlight cursor at low speed and a circular area cursor at high speed. Thus, it enables the user(More)
Virtualization is one of the key enablers in cloud computing. At the same time, though, it is also widely considered as a double-edged sword that may cause information leakage between virtual machines (VM) co-residing on the same physical server via various cross-VM covert channels. In this paper, we first explore the impact of different bystander workloads(More)
Touch input is increasingly popular nowadays, especially for mobile devices such as smartphones and tablet computers. However, the human finger has considerably large fingertip size and finger input is imprecise. As such, acquiring small targets on a touch screen is still a challenging task. In this paper, we present the <i>LinearDragger</i>, a new and(More)
Touch input is increasingly popular nowadays. The human finger has considerably large fingertip size and finger input is imprecise. Acquiring small targets on a touch screen is still a challenging task. In this extended abstract, we present the <i>LinearDragger</i>, a new and integrated one-finger target acquisition technique for small and clustered(More)
Mid-air gestures have become an important interaction technique in natural user interfaces, especially in augmented reality and virtual reality. Supporting a set of continuous gesture-based commands in mid-air gesture interaction systems, such as selecting and moving then placing an object, however, remains to be a challenge. This is largely because these(More)
