the application of a flight simulator with six degree of freedom (6dof)) in design and analysis of rocket systems is essential. the calibration of a 6dof flight simulator is a challenging problem. this paper focuses on the calibration of a flight simulator and intends to answer the following questions: 1) does experimental design have significant impact on calibration quality? if so, which expe...

In this paper, we developed a new haptic interface SPIDAR-G&G system to take advantage of the user's existing two hands skills for completing the continuous and compound task in a virtual world. A user cannot only manipulate the 3D objects with 6DOF translational and rotational motion by using the grip which located in the workspace of two frames, but also get the 6DOF force feedback, 3DOF for ...

This paper describes a new six degree of freedom haptic interface with a large translational and rotational range of motion. The 6DOF haptic interface is demonstrated with an example industrial-scale virtual prototyping simulation which shows a moderately complex object interacting with an arbitrarily complex virtual environment, using a full-service collision detection and response package to ...

Training systems for dental implantology that are based on virtual reality need a precise haptic feedback with six Degrees of Freedom (6DoF) This is particularly challenging when using real patient data for the jawbone and during the interactive simulation of drilling. In this paper, we present our simulator and two complementary contributions: The first one is a method for 6DoF haptic renderin...

Cone-beam CTs (CBCTs) installed on a linear accelerator can be used to provide fast and accurate automatic six degrees of freedom (6DoF) vector displacement information of the patient position just prior to radiotherapy. These displacement corrections can be made with 6DoF couches, which are primarily used for patient setup correction during stereotactic treatments. When position corrections ar...

This paper describes a technical solution that has been devised to embed the SensAble PHANTOM 6dof force feedback device with a light-weight 6dof force sensor from ATI: the Nano43. The design has been made in a way such that original performances are kept in terms of force feedback and sensing.

PURPOSE Clinical evaluation of a "virtual" methodology for providing 6 degrees of freedom (6DOF) patient set-up corrections and comparison to corrections facilitated by a 6DOF robotic couch. METHODS A total of 55 weekly in-room image-guidance computed tomographic (CT) scans were acquired using a CT-on-rails for 11 pelvic and head and neck cancer patients treated at our facility. Fusion of the...

Multitouch input devices afford effective solutions for 6DOF (six Degrees of Freedom) manipulation of 3D objects. Mainly focusing on large-size multitouch screens, existing solutions typically require at least three fingers and bimanual interaction for full 6DOF manipulation. However, single-hand, two-finger operations are preferred especially for portable multitouch devices (e.g., popular smar...

This thesis work was performed at the research centre CINECA in Bologna, Italy. An interface with six degrees of freedom, 6DOF, to be used in a virtual environment for the positioning of medical components was developed in cooperation with IOR, one of the most important orthopaedic hospitals in Italy. The main reason for doing this was to find out whether or not a virtual environment and 6DOF i...

This article is presenting a method for simultaneous localization and mapping (SLAM) of mobile robots in six degrees of freedom (DOF). The localization and mapping task is equal to the registration of multiple 3D images into a common frame of reference. For this purpose, a method based on the Iterative Closest Point (ICP) algorithm was developed. The SLAM method originally implemented in this r...
