Path planning for encountered-type haptic devices that render multiple objects in 3D space

A path-planning algorithm for encountered-type haptic devices that render multiple virtual objects in 3D space is proposed. To render multiple virtual objects with a single haptic device, the following two behaviors must be realized: (i) the device should move to the target object location in advance of the users hand so that the user can encounter it; (ii) otherwise, the device should keep away from the users hand, avoiding an unexpected collision. To realize such a consistent encounter, the users hand motion must be tracked. The proposed algorithm determines the device location based on the minimum distance problem between a point (the users hand) and a convex polyhedron constructed from the reference points of multiple objects. An automobile virtual control panel was constructed using an encountered-type haptic device in which the proposed path-planning algorithm was implemented. The validity of the proposed algorithm was confirmed and the required performances, such as the device speed and the accuracy of hand tracking were evaluated.

Virtualizing Service Infrastructure with Hardware Gateway in Data Center

Service providers have been struggling with service infrastructure management in their data centers like taking care of excess or shortage of physical resources. To solve the issue, we propose virtualization of service infrastructure by connecting physical resources with hardware gateway and virtualize network traffic among physical resources. With this approach, service providers can make their service infrastructure more flexible and dynamically change service infrastructure configuration like adding or removing physical resources on demand.
