Development of 6DOF Finger-mounted Haptic Device for Operation with Two Fingers.

Two-Finger Gestures for 6DOF Manipulation of 3D Objects

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...

Development of Two-Handed Multi-finger Haptic Interface SPIDAR-10

Supportive Pointing Operation by Haptic Device

We developed a haptic device that uses a trackball to enable the user to recognize the direction of its movement through touch. The trackball with haptic feedback supports the subtle operation that is peculiar to a pointing device, so that users can easily point to even a small object on a screen. The haptic device developed in the present study possesses the characteristics of "compactness," "...

Detection for Haptic Exploration with Robotic Fingers

The authors consider the detection of small surface features, such as cracks, bumps, and ridges, on the surface of an object during haptic exploration and dexterous manipulation. Surface feature definition and detection are essential for intelligent haptic exploration and modeling of unknown objects. First, the authors review the representation of object surface geometry and present definitions...

Head-Mounted Sensory Augmentation Device: Comparing Haptic and Audio Modality

This paper investigates and compares the effectiveness of haptic and audio modality for navigation in low visibility environment using a sensory augmentation device. A second generation head-mounted vibrotactile interface as a sensory augmentation prototype was developed to help users to navigate in such environments. In our experiment, a subject navigates along a wall relying on the haptic or ...
