An Interactive Wireless Morse Code Learning System
Morse code has been shown to be a valuable tool in assistive technology, augmentative and alternative communication, and rehabilitation for some people with various conditions, such as spinal cord injuries, non-vocal quadriplegics, and visual or hearing impairments. In this article, a mobile phone human-interface system using Morse code input device is designed and implemented for the person wi...
متن کاملSome Algebraic Aspects of Morse Code Sequences
1 Morse code polynomials Morse code sequences are finite sequences of dots (•) and dashes (−). If a dot has length 1 and a dash has length 2 then the number of all such sequences of total length n−1 is the Fibonacci number Fn, which is defined as the sequence of numbers satisfying the recursion Fn = Fn−1 + Fn−2 with initial conditions F0 = 0 and F1 = 1. If a dash is assumed to have length j, j≥...
متن کاملThe Tap code - a code similar to Morse code for communication by tapping
A code is presented for fast, easy and efficient communication over channels that allow only two signal types: a single sound (e.g. a knock), or no sound (i.e. silence). This is a true binary code while Morse code is a ternary code and does not work in such situations. Thus the presented code is more universal than Morse and can be used in much more situations. Additionally it is very tolerant ...
متن کاملA Novel Approach to Mandarin Morse Code Recognition
Computers are being used in an increasing variety of fields. Especially, combining electronic and wireless technologies is emerging as a major trend. Most products manufactured now, however, are designed for abled persons and thus often inaccessible to the persons with disabilities. Often, persons with disabilities need adaptive tools to use the technological devices originally designed for abl...
متن کاملWeb accessibility by Morse Code modulated haptics for deaf-blind
Providing information using a modality that is both non-visual and non-auditory such as haptic feedback, may be a viable approach regarding web accessibility for deaf-blind. Haptic navigation systems have been shown to be easy to learn (Venesvirta, 2008), and modulating navigation related information as patterns of vibrations has been shown to be perceived as natural and nonintrusive (Szymzcak,...
