Using Haptics to Convey Cause-and-Effect Relations in Climate Visualization
Found in: IEEE Transactions on Haptics
By Nesra Yannier, Cagatay Basdogan, Serdar Tasiran, Omer Lutfi Sen
Issue Date:July 2008
pp. 130-141
We investigate the potential role of haptics in climate visualization. In existing approaches to climate visualization, different dimensions of climate data such as temperature, humidity, wind, precipitation, and cloud water are typically represented using...
 
VR-Based Simulators for Training in Minimally Invasive Surgery
Found in: IEEE Computer Graphics and Applications
By Cagatay Basdogan, Mert Sedef, Matthias Harders, Stefan Wesarg
Issue Date:March 2007
pp. 54-66
Simulation-based training using VR techniques is a promising alternative to traditional training in minimally invasive surgery (MIS). Simulators let the trainee touch, feel, and manipulate virtual tissues and organs through the same surgical tool handles u...
 
Real-Time Finite-Element Simulation of Linear Viscoelastic Tissue Behavior Based on Experimental Data

Issue Date:November 2006
pp. 58-68
The lack of experimental data on the viscoelastic material properties of live organ tissues has been a significant obstacle in the development of realistic models. A real-time and realistic finite-element simulation of viscoelastic tissue behavior using ex...
 
AVirtual Reality Toolkit for Path Planning and Manipulation at Nano-scale
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Aydin Varol, Ihsan Gunev, Cagatay Basdogan
Issue Date:March 2006
pp. 73
A virtual reality (VR) toolkit that integrates the human operator into a virtual environment by means of visual and haptic feedback has been developed to design and test manipulation strategies at nano-scale. Currently, the toolkit is capable of modeling t...
 
Haptic Manipulation of Microspheres Using Optical Tweezers
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Ibrahim Bukusoglu, Cagatay Basdogan, Alper Kiraz, Adnan Kurt
Issue Date:March 2006
pp. 55
We report the manipulation of glass microspheres having a diameter of 3-10 .m using optical tweezers and with haptic feedback. We detect the position of a microsphere manipulated in a fluid bed using a CCD camera and calculate the forces acting on it due t...
