3D devices

3D Mouse

3D navigation devices revolutionize the user interaction with 3D applications. With these devices it becomes possible for a user to pan, zoom and rotate the model or camera as if he were holding it in his hand. It’s a level of control that’s simply is not possible with a traditional mouse and keyboard. The user’s imagination alone controls all virtual interactions, whether he is working on complex assemblies, 3D models or fly-throughs. Using standard mouse and keyboard requires separate individual steps. The 3D mouse allows the user to control the camera or 3D object through one single device with one hand in all degrees of freedom.

VR glove

The wired VR-glove is a glove-like input device for human-computer interaction in virtual reality environments. Various sensors are used to capture physical data such as bending of fingers and hand movements. These movements are then interpreted by software. With a VR-glove a user can control a 3D scene in the most natural way, by the movement of his hands and fingers. Through simple movements, it becomes possible for the user to grasp, move objects and control the 3D scene.

Haptic device

Tactile or touch feedback is the term applied to sensations felt by the skin. Tactile feedback allows users to feel things such as the textures of surfaces, temperature and vibration. Force feedback reproduces directional forces that can result from solid boudaries, the weight of grasped virtual objects, mechanical compliance of an object and inertia.

Haptic devices are human-computer interaction devices that give a perception of tactile and force feedback. They allow users to touch, feel and manipulate three-dimensional objects in virtual environments and tele-operated systems.
Haptic devices offered are input-output devices, meaning that they track a user’s physical manipulations (input) and provide realistic touch sensations coordinated with on-screen events (output).

Tracking devices (wired and wireless)

Tracking devices are intrinsic components that can be integrated to the VR system. These devices communicate with the system’s processing unit, telling it the orientation of a user’s point of view. In systems that allow a user to move around within a physical space, trackers detect where the user is, the direction he is moving and his speed.

There are several different kinds of tracking systems integrated into VR systems, but all of them have a few things in common. They can detect six degrees of freedom (6-DOF) — these are the object’s position within the x, y and z coordinates of a space and the object’s orientation. Orientation includes an object’s yaw, pitch and roll.

Based on application requirements we can offer:

electromagnetc tracking systems
optical tracking systems
mechanical tracking systems
