Although intelligent interactive systems have been the focus of many research efforts, very few have addressed systems for individuals with disabilities. This article presents our methodology for an intelligent interactive system that provides individuals with sight impairments with access to the content of information graphics (such as bar charts and line(More)
This paper presents the SIGHT (Summarizing Information GrapHics Textually) system that enables visually impaired users to gain access to information graphics that appear on a web page. The user interface is implemented as a browser extension that is launched by a keystroke combination. The output of SIGHT is a textual summary of the graphic, the core(More)
Information graphics (such as bar charts and line graphs) play a vital role in many multimodal documents. Unfortunately, visually impaired individuals who use screen reader programs to navigate through such documents have limited access to the graphics. This paper presents the <i>Interactive</i> SIGHT (Summarizing Information GrapHics Textually) system that(More)
Molecular hydrogen is widely used by microorganisms as a source of energy. One of the best studied aerobic hydrogen oxidizers, the beta-proteobacterium Ralstonia eutropha (formerly Alcaligenes eutrophus), harbors two distinct [NiFe]-hydrogenases which catalyze the heterolytic cleavage of H2 into 2H+ and 2e-. The genes encoding the hydrogenase subunits are(More)
<i>Interactive</i> SIGHT is a system that is intended to provide people with visual impairments access to the kind of information graphics found in popular media (i.e., electronic newspapers or magazines). The majority of such graphics are intended to convey a message; the graphic designer chose the graphic and its design in order to make a point.(More)
Information graphics such as bar charts, line graphs, and pie charts play a vital role in many documents found on the Web. In contrast to graphics generated for the purposes of data visualization, which are intended to allow the viewer to visually explore the data, we posit that the majority of information graphics that appear in popular media are designed(More)
We built a high-speed, digital mean-field Boltzmann chip and SBus board for general problems in constraint satjsfaction and learning. Each chip has 32 neural processors and 4 weight update processors, supporting an arbitrary topology of up to 160 functional neurons. On-chip learning is at a theoretical maximum rate of 3.5 x 10 8 connection updates/sec;(More)
