    1. Euler angles: conversion of arbitrary rotation sequences to specific rotation sequence (pages 521–529)

      A new method is introduced to convert arbitrary rotation sequences to specific rotation sequence of choice, without experiencing gimbal lock phenomena. The new method is later utilized in development of a MATLAB-Simulink program with six-degrees-of-freedom (6DoF) animation block. The program enables the users to alter a missile's projectile path and graphically see kinematics of a missile body in three-dimensional spaces.

    2. Natural preparation behavior synthesis (pages 531–542)

      Hubert P.H. Shum, Ludovic Hoyet, Edmond S.L. Ho, Taku Komura and Franck Multon

      In this paper, we propose a new method to produce preparation behaviors using reinforcement learning and online posture optimization. Our trained controller drives a character to move to a target with the appropriate level of preparation, resulting in a humanlike behavior. We create scenes in which the character realistically moves in a complex environment and interacts with objects, such as crawling under and jumping over obstacles while walking.

    3. Person re-identification with local descriptors across multicameras (pages 543–551)

      Qiao Huang and Jie Yang

      Article first published online: 11 OCT 2013 | DOI: 10.1002/cav.1556

      In the topic of person re-identification, robustness against low resolution, occlusion and pose, viewpoint and illumination changes is achieved in a very fast way.

    4. A faster triangle-to-triangle intersection test algorithm (pages 553–559)

      Wei Ling-yu

      Article first published online: 11 OCT 2013 | DOI: 10.1002/cav.1558

      By computing the line segment between a triangle's plane and the other triangle, and dividing cases by the segment's location, the algorithm uses at most 87 operations and 29% less time in detecting triangles' intersection.

    5. Evaluation of grounded isometric interface for whole-body navigation in virtual environments (pages 561–575)

      Bong-gyu Jang and Gerard Jounghyun Kim

      Article first published online: 24 OCT 2013 | DOI: 10.1002/cav.1561

      Key findings: We present an experimental study indicating that passive whole-body interaction using the isometric grounded interaction device such as the G-Bar can induce a relatively high level of presence and immersion by emulating active force feedback.
