Equipped with a 20-cell 8-dot display, the Orbit Reader 20 is based on revolutionary braille cell technology developed by Orbit Research. The breakthrough technology uses mainstream components and manufacturing processes to enable unique signage-quality refreshable braille at a fraction of the cost of the piezoelectric technology that has been used in braille cells so far.
When used as a standalone reader, it enables the user to read any file from the SD card. These could be BRF and BRL formatted books, text files or files in any format. This allows students, especially in developing countries, to have content loaded on to the SD card by teachers and use the unit without any live connectivity to a computer or the internet. The reader has features for easy navigation, inserting and editing bookmarks, browsing through folders, etc.
As a braille display, the Orbit Reader connects to PCs and Macs, iOS devices and Android devices. It provides Bluetooth and USB connectivity and can connect simultaneously to multiple devices. Using the screen reading capability on the computing device, such as Voiceover, Brailleback or popular PC screen readers the user can control the functions of their computer or smartphone, use their favourite apps, read and send text messages and email and browse the internet.
As a note-taker, the Orbit Reader offers all essential file creation and editing functions. A user can create new files, save them on SD card and edit existing files. The Orbit Reader also includes file management features, allowing the user to rename, delete, copy, and create folders and files.
While it offers a host of features, the Orbit Reader 20 is extremely easy to use and allows seamless and instantaneous switching between reader, note-taker and braille display modes, as well as selection between connected devices such as a computer or phone.
The Orbit Reader 20 is very compact, measuring a little over an inch in height and about 6 inches by 4 inches and weighing under a pound. It includes a high-quality Perkins style keyboard with 8 keys and a space bar. It also has a cursor pad with 4 arrow keys and a select button, as well as rocker keys on each side of the braille display to control navigation.
The unit is powered by a user-replaceable fast-charging lithium battery which is recharged through the USB port. It is fluid and dust resistant and its construction is optimized for durability in extreme environmental conditions.

Central Access Reader (CAR) is a free, open source, text-to-speech application designed specifically for students with print-related disabilities. CAR reads Microsoft Word documents and pasted text using the voice installed on your computer. CAR has an intuitive interface and many customizable features.
Print Disability means a disability that prevents a user from effectively utilizing print material and may include blindness, other serious visual impairments, specific learning disabilities or the inability to hold a book.
CAR is not screen-reader compatible. However, CAR can export documents as a fully accessible HTML file. We are currently working on an interface that will allow blind users to export content to HTML and MP3 independently.

Do you have a meeting or event and want to track attendance? Are you taking payments for T-shirt sales or other items and would like to accept Lancer CA$H? If your answer is yes, then you should check-out a card reader from the Lancer Card & Campus Services Office.
Clojure is a homoiconic language, which is a fancy term describing the fact that Clojure programs are represented by Clojure data structures. This is a very important difference between Clojure (and Common Lisp) and most other programming languages - Clojure is defined in terms of the evaluation of data structures and not in terms of the syntax of character streams/files. It is quite common, and easy, for Clojure programs to manipulate, transform and produce other Clojure programs.
That said, most Clojure programs begin life as text files, and it is the task of the reader to parse the text and produce the data structure the compiler will see. This is not merely a phase of the compiler. The reader, and the Clojure data representations, have utility on their own in many of the same contexts one might use XML or JSON etc.
One might say the reader has syntax defined in terms of characters, and the Clojure language has syntax defined in terms of symbols, lists, vectors, maps etc. The reader is represented by the function read, which reads the next form (not character) from a stream, and returns the object represented by that form.
Since we have to start somewhere, this reference starts where evaluation starts, with the reader forms. This will inevitably entail talking about data structures whose descriptive details, and interpretation by the compiler, will follow.
'.' has special meaning - it can be used one or more times in the middle of a symbol to designate a fully-qualified class name, e.g. java.util.BitSet, or in namespace names. Symbols beginning or ending with '.' are reserved by Clojure. Symbols containing / or . are said to be 'qualified'.
Integers can be indefinitely long and will be read as Longs when in range and clojure.lang.BigInts otherwise. Integers with an N suffix are always read as BigInts. Octal notation is allowed with a 0 prefix, and hexadecimal notation is allowed with a 0x prefix. When possible, they can be specified in any base with radix from 2 to 36 (see Long.parseLong()); for example 2r101010, 052, 8r52, 0x2a, 36r16, and 42 are all the same Long.
Characters - preceded by a backslash: \c. \newline, \space, \tab, \formfeed, \backspace, and \return yield the corresponding characters. Unicode characters are represented with \uNNNN as in Java. Octals are represented with \oNNN.
Map literals can optionally specify a default namespace context for keys in the map using a #:ns prefix, where ns is the name of a namespace and the prefix precedes the opening brace { of the map. Additionally, #:: can be used to auto-resolve namespaces with the same semantics as auto-resolved keywords.
Keys that are keywords or symbols with a namespace are not affected except for the special namespace _, which is removed during read. This allows for the specification of keywords or symbols without namespaces as keys in a map literal with namespace syntax.
The keyed values in the map are assigned unevaluated to the relevant fields in the defrecord. Any defrecord fields without corresponding entries in the literal map are assigned nil as their value. Any extra keyed values in the map literal are added to the resulting defrecord instance.
The behavior of the reader is driven by a combination of built-in constructs and an extension system called the read table. Entries in the read table provide mappings from certain characters, called macro characters, to specific reading behavior, called reader macros. Unless indicated otherwise, macro characters cannot be used in user symbols.
Metadata is a map associated with some kinds of objects: Symbols, Lists, Vector, Sets, Maps, tagged literals returning an IMeta, and record, type, and constructor calls. The metadata reader macro first reads the metadata and attaches it to the next form read (see with-meta to attach meta to an object):
^:a 1 :b 2 [1 2 3] yields the vector [1 2 3] with a metadata map of :a 1 :b 2.
A shorthand version allows the metadata to be a simple symbol or string, in which case it is treated as a single entry map with a key of :tag and a value of the (resolved) symbol or string, e.g.:
^String x is the same as ^:tag java.lang.String x
Another shorthand version allows the metadata to be a keyword, in which case it is treated as a single entry map with a key of the keyword and a value of true, e.g.:
^:dynamic x is the same as ^:dynamic true x
A regex pattern is read and compiled at read time. The resulting object is of type java.util.regex.Pattern. Regex strings do not follow the same escape character rules as strings. Specifically, backslashes in the pattern are treated as themselves (and do not need to be escaped with an additional backslash). For example, (re-pattern "\\s*\\d+") can be written more concisely as #"\s*\d+".
For Symbols, syntax-quote resolves the symbol in the current context, yielding a fully-qualified symbol (i.e. namespace/name or fully.qualified.Classname). If a symbol is non-namespace-qualified and ends with '#', it is resolved to a generated symbol with the same name to which '_' and a unique id have been appended. e.g. x# will resolve to x_123. All references to that symbol within a syntax-quoted expression resolve to the same generated symbol.
For Lists/Vectors/Sets/Maps, syntax-quote establishes a template of the corresponding data structure. Within the template, unqualified forms behave as if recursively syntax-quoted, but forms can be exempted from such recursive quoting by qualifying them with unquote or unquote-splicing, in which case they will be treated as expressions and be replaced in the template by their value, or sequence of values, respectively.
