With the ever increasing availability of the Internet and electronic media rich in graphical and pictorial information - for communication, commerce, entertainment, art, education - it has been hard for the visually impaired community to keep up. We propose a non-invasive system that can be used to convey graphical and pictorial information via touch and(More)
Common controls for photographic editing can be difficult to use and have a significant learning curve. Often, a user does not know a direct mapping from a high-level concept (such as " soft ") to the available parameters or controls. In addition, many concepts are subjective in nature, and the appropriate mapping may vary from user to user. To overcome(More)
BACKGROUND Monoclonal anti-IgE antibody omalizumab is a promising therapeutic option in patients with chronic urticaria (CU) resistant to non-sedating H1-antihistamines (nsAH). However, data about its long-term efficacy and safety are still scant. OBJECTIVE We retrospectively analysed the clinical course of patients with severe recalcitrant CU that were(More)
In previous work, we have proposed a dynamic, interactive system for conveying visual information via hearing and touch. The system is implemented with a touch screen that allows the user to interrogate a two-dimensional (2-D) object layout by active finger scanning while listening to spatialized auditory feedback. Sound is used as the primary source of(More)
We propose a new algorithm for the inference of minimum size nite state machines from training set data. Our approach is based on a well known search algorithm proposed by Bierman, but it incorporates a set of techniques known as dependency directed back-tracking. Although these techniques have already been used in other applications, we believe we are the(More)
