“…In [12], a 3D model reconstructed from multiple images is used for haptic rendering while auto-stereoscopic display is used for visualization of the model. In [13], haptic interaction with a reconstructed model from stereo images captured by cameras mounted on shoulders of a blind user has been proposed to enhance visually impaired users' navigation capabilities.…”

Haptic interaction significantly augments our experience with a computer and in cyberworlds in particular. However, haptic interaction requires the content creators to make physical or haptic models of the virtual objects while it is not always possible or feasible, especially when it comes to using real images or videos as elements of interaction. We, therefore, propose to use image-driven haptic rendering where a displayed image, real or simulated, is used as a source of the force-feedback calculations at any pixel touched by the haptic device. We introduce the main idea and describe how it is implemented as a core algorithm for image-driven haptic rendering, as well as for a few particular cases of haptic rendering of different dominant colors, textures and contours of the objects displayed in the images. Implementations of the proposed method to desktop tangible image application and haptic video communication on the web are presented as a proof of concept.

“…Since the difficulty of perceiving physical objects through hepatic user interfaces, many researchers have taken different approaches to solve this problem, specifically the information of perceptual level [23-26]. Object features may be classified into predetermined perceptual categories, and then subsequently conveyed to users to invoke mental concepts [24]. This method is much easier as compared to working with physical representations, and can enable users to perceive remote objects in real-time.…”

In this paper, we present a new framework to monitor medication intake for elderly individuals by incorporating a video camera and Radio Frequency Identification (RFID) sensors. The proposed framework can provide a key function for monitoring activities of daily living (ADLs) of elderly people at their own home. In an assistive environment, RFID tags are applied on medicine bottles located in a medicine cabinet so that each medicine bottle will have a unique ID. The description of the medicine data for each tag is manually input to a database. RFID readers will detect if any of these bottles are taken away from the medicine cabinet and identify the tag attached on the medicine bottle. A video camera is installed to continue monitoring the activity of taking medicine by integrating face detection and tracking, mouth detection, background subtraction, and activity detection. The preliminary results demonstrate that 100% detection accuracy for identifying medicine bottles and promising results for monitoring activity of taking medicine.

“…Real-time calculation of depth without the use of dedicated hardware recently became feasible [14][15][16][17]. Ansar et al [15] use bilateral filtering, while MMX-optimised code of a three-dimensional similarity accumulator is used by Schmidt et al [16].…”
