This paper presents gaze-dependent depth-of-field (DOF) rendering setup, consisting of high frequency eye tracker connected to a graphics workstation. A scene is rendered and visualised with the DOF simulation controlled by data captured with the eye tracker. To render a scene in real-time, the reverse-mapped z-buffer DOF simulation technique with the blurring method based on Poisson disk is us...

Abstract Variable Stiffness Actuator (VSA) is the core mechanism to achieve physical human–robot interaction, which an inevitable development trend in robotic. The existing variable stiffness actuators are basically single degree-of-freedom (DOF) rotating joints, achieving multi-DOF motion by cascades and resulting complex robot body structures. In this paper, integrated 2-DOF actuator with pro...

In this letter, we present the first characterization for the achievable Degrees-of-Freedom (DoF) by Blind Interference Alignment (BIA) using staggered antenna switching in the K-user Gaussian Interference Channel. In such scheme, each transmitter is equipped with one conventional antenna and each receiver is equipped with one reconfigurable (multi-mode) antenna. Assuming that the channel is kn...

Concern over the impending retirement of several top-level managers led a county agency to engage in efforts aimed at more efficient succession management. Administrators developed plans to prevent the loss of invaluable knowledge and wisdom accompanying retirement of experienced agency leaders. The agency's Director of Finance (DoF) was one of the first key figures projected to retire, and a s...

Interactively creating and editing 3D content requires the manipulation of many degrees of freedom (DoF). For instance, docking a virtual object involves 6 DoF (position and orientation). Multi-touch surfaces are good candidates as input devices for those interactions: they provide a direct manipulation where each finger contact on the table controls 2 DoF. This leads to a theoretical upper bou...

In this paper, degrees of freedom (DoF) is investigated for theM×N single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). It is known that the sum DoF of 2-user SISO X channel with synergistic alternating CSIT is the same as the sum DoF of 2-user (M = N = 2) SISO X channel with perfect CSIT [8]. In this paper, such 2-user X channel sch...

Vision-based techniques used in automatic micromanipulation are limited by small depth of field (DOF) because of high magnification and big numerical aperture of optical system. This paper proposed a new adaptive DOF image system which can adaptively adjust DOF during micromanipulation while maintaining high resolution of the images. The proposed system uses a spatial light modulator instead of...

This paper deals with the experimental identification of the dynamic parameters of parallel machines. The dynamic parameters are estimated by using the weighted least squares solution of an over determined linear system obtained from the sampling of the dynamic model along a closed loop exciting trajectory. Experimental results are exhibited for the H4 robot, a fully parallel structure providin...

In this paper, the 3-user Gaussian MIMO interference channel is considered. The asymmetric distribution of the DoF, where different users have different number of DoF, is studied. Two cases are presented, the first is when all transmitters and receivers have equal number of antennas M , the other when the transmitters have M antennas each, while the receivers have N antennas each. It is assumed...
