For leveraging multiple GPUs in a cluster system, it is necessary to assign application tasks to multiple GPUs and execute those tasks with appropriately using communication primitives to handle data transfer among GPUs. In current GPU programming models, communication primitives such as MPI functions cannot be used within GPU kernels. Instead, such(More)
The tilting operation has been shown to be useful in expanding the input vocabulary of a small device; therefore, this operation could also be useful in expanding the input vocabulary of wrist-worn devices. In this study, in order to explore new design guidelines of GUI and operation methods for smartwatches, we have investigated the accuracy of the tilting(More)
We present a target selection technique using mid-air interaction behind a smartphone for mobile virtual reality (VR) environments. This is realized by using a smartphone as a head-mounted display with a cardboard viewer. Our technique displays a pointer on the screen corresponding to the position of the hand, which is detected by the built-in back camera(More)
In this work, we use AirFlip to undo text input on mobile touchscreen devices. AirFlip involves a quick double crossing in-air gesture in the boundary surfaces of hover zone of devices that have hover sensing capability. To evaluate the effectiveness of undoing text input with AirFlip, we implemented two QWERTY soft keyboards (AirFlip keyboard and Typical(More)
