A haptic device using flexible sheet such as rubber has already been proposed. Controlling the bias tension of the sheet, the device varies compliance of the sheet in the normal direction; users can feel compliance of various virtual objects if they touch the sheet. This device is integrated into a visual and haptic display. The haptic device uses transparent flexible sheet, and a liquid crysta...

Frozen section and touch imprint cytology are important diagnostic procedures for surgeons during operation and must be accurate if the patient is to receive maximum benefit. To assess the accuracy of intraoperative pathologic consultation including frozen section and touch imprint cytology during a five year period (1995- 2000), a retrospective survey of 1000 consecutive cases of frozen s...

Touch-sensitive screens enable natural interaction without any instrumentation and support tangible feedback on the touch surface. In particular multi-touch interaction has proven its usability for 2D tasks, but the challenges to exploit these technologies in virtual reality (VR) setups have rarely been studied. In this paper we address the challenge to allow users to interact with stereoscopic...

In this paper, we introduce a novel computer vision based attack that discloses inputs on a touch enabled device, while the attacker cannot see any text or popups from a video of the victim tapping on the touch screen. In the attack, we use the optical flow algorithm to identify touching frames where the finger touches the screen surface. We innovatively use intersections of detected edges of t...

prototypes, a novel interaction system for blind users, which is especially designed and developed for non-visual touch screen devices and their applications. The FBT prototypes were developed with virtual keys to be identified based on finger holding positions. Two different models namely the single digit FBT and double digit FBT were propounded. FBT technique were applied using two different ...

Virtual touch screen using camera is an ordinary screen which uses a camera to imitate the touch screen by taking a picture of an indicator, e.g., finger, which is laid on the screen, converting the indicator tip position on the picture to the position on the screen, and moving the cursor on the screen to that position. In fact, the indicator is not laid on the screen directly, but it is interv...

With the popularity of touchscreen tablets and gesture control devices, the role of touch in online consumer behavior has become increasingly important. This study aims to investigate how sense of touch evoked by various interaction modes (i.e., mouse-driven interaction, touchscreen gesture interaction and mid-air gesture interaction) influences virtual product experience. Drawing on Feelings-a...
