Haptic lnteraction in Virtual Environments
نویسندگان
چکیده
We present a haptic rendering framework that allows the tactile display of coniplex virtual environments. This framework allows surface constraints, surface shading, friction, texture and other ejjects to be modeled solely by updaring the position of a representative object, the “virtual proxy.” This abstraction reduces the task of the haptic servo control loop to the minimization of the error between user’s position and that of the proxy. This framework has been implemented in a system that is able to haptically render virtual environments of a complexity that is near and ofen in excess of the capabilities of current interactive graphic systems.

متن کاملThe perception of texture , object size and angularity by touch in virtual environments with two haptic devices .
The incorporation of the sense of touch (haptic sense) into virtual reality (VR) has considerable potential to enhance the realism of virtual environments and make VR accessible to blind people. This paper summarises a series of investigations into the haptic perception of texture and object size/angularity in VR, with two haptic devices. Guidelines for the creation of haptic environments for b...
متن کاملUm Estudo sobre a utilização de Sistemas Hápticos em Ambientes Virtuais Colaborativos
Collaborative Virtual Environments are virtual environments where multiple users may share the same space and participate in any collaborative activity. The use of haptic systems in these environments allows, in certain types of tasks, a more natural interaction and can improve users’ performance and feeling of immersion in the experiment. This paper presents the use of haptic systems in collab...
متن کاملCollaborative Evaluation of a Haptic-based Medical Virtual Environment
There is increasing use of virtual environments for medical training applications. Simulated medical environments allow clinical staff to practise medical procedures without endangering patients. Haptic devices are a key technology in many such systems adding a sense of touch to virtual interactions allowing healthcare practitioners to practise and test their clinical skills in life-like situat...
متن کاملFlexible and Configurable Haptic Environments through Virtual Graphical Force Sensors
This paper presents a solution to virtual sensors which enables users to create virtual haptic environments in a flexible, easy to use and time efficient manner. The usefulness of virtual sensors has been shown in a number of applications, such as telepresent micro-assembly, in which haptic feedback is often desired without mechanical impact with a “real” sensor. Instead of requiring each virtu...
