Despite recent advances, blind students, researchers, and professionals lack easy access to mathematical resources. This lack of access is a barrier to higher education for many blind students and puts them at an unfair disadvantage in school, academia, and industry. A survey of current mathematical accessibility technologies for blind persons is covered in this paper, encompassing reading, wri...

The ability to identify schematic knowledge is an important goal for both assessment and instruction. In the current paper, schematic knowledge of statistical probability theory is explored from the declarative-procedural framework using multiple methods of assessment. A sample of 90 undergraduate introductory statistics students was required to classify 10 pairs of probability problems as simi...

The objective of this study was to design and evaluate new dynamic text-editingmethods (chatting, instant messenger) using a foot pedal control. A first experiment was to assess whether the foot-based method enhanced editing performance compared to conventional mouse use and to identify which type of foot control is most convenient for users. Five prototype methods including four new methods (t...

Tools for visualizing and creating groundtruth and metadata are crucial for document image analysis research. In this paper, we describe TrueViz which is a tool for visualizing and editing groundtruth/metadata for OCR. TrueViz is implemented in the Java programming language and works on various platforms including Windows and Unix. TrueViz reads and stores groundtruth/metadata in XML format, an...

Effective authoring aids, whether for novice, secondlanguage, or experienced writers, require linguistic knowledge. With respect to depth of analysis, authoring aids that aim to support revising and editing go beyond POS-tagging but cannot work on complete, mostly well-formed sentences to perform deep syntactic analysis, since a text undergoing revision is in a constant state of flux. In order ...

We present a text-based tool for editing talking-head video that enables an iterative workflow. On each iteration users can edit the wording of speech, further refine mouth motions if necessary to reduce artifacts, and manipulate non-verbal aspects performance by inserting gestures (e.g., smile) or changing overall style energetic, mumble). Our requires only 2 3 minutes target actor it synthesi...

Revising and editing are important parts of the writing process. In fact, multiple revision and editing cycles are crucial for the production of high-quality texts. However, revising and editing are also tedious and error-prone, since changes may introduce new errors. Grammar checkers, as offered by some word processors, are not a solution. Besides the fact that they are only available for few ...

Controlled Language (CL) for Ontology Editing tools offer an attractive alternative to naive users, wishing to create Ontologies. However despite the benefits of CLs, users are still required to learn the correct syntactic structures in order to use the Controlled Language properly. Referring to CL vocubulary/syntax rules can be time consuming, annoying and in certain cases may prevent uptake o...
