An Indian graduate student has designed a mobile phone application that enables people
with sight and hearing impairments to send and receive text messages.
The PocketSMS application was developed for Android smartphones, which are generally
cheaper than Apple's iPhones. The application converts text into Morse code vibrations
so that users can "feel" the message.
Regular mobile phones already use vibrations to alert users to incoming calls or messages.
Anmol Anand, a graduate student at the Guru Gobind Singh Indraprastha University in
Delhi, realized that the same vibrations could also convey text message content.
He used the open source Google App Inventor to write a new application to covert each
letter in a text message into Morse code in which each letter corresponds to a set
of a short and long tones and then used the phone's hardware to vibrate for each
letter.
An accompanying application, MorseTrainer, has been designed to teach deaf-blind users
Morse code, and to use it without having to rely on smartphone keyboards, which can
be difficult to see.
Text messaging is growing in importance as a tool for safety and
social inclusion. In the Democratic Republic of the Congo late last year, for instance,
a group of deaf users protested for their safety late last year when the government
shut down text messaging services, the BBC reported.
In Uganda, the National Association of the Deaf is working on a
project in which hearing students and deaf students learn how to send text messages
together. "We saw that deaf kids were not integrating", said education consultant
Sacha DeVelle, who was volunteering in Kabale with the charity Cambridge to Africa.
When teachers began showing pairs of hearing and deaf students how to send text messages,
deaf children became far more integrated into the school community. "It encourages
them to go on and do what they want to do, [for example] go to university or set up
a shop", DeVelle said.
Anand's collaborator, Arun Mehta president of the Bidirectional Access Promotion
Society (BAPSI) said that internet access is just as important for the disabled
as everyone else. He said that the introduction of text-to-speech screen reading software
had meant that "the gap between the sighted and the blind has shrunk dramatically.
We would like to do that for the deaf-blind too."
Inclusive technology can help disabled people take part in everyday life, said Mohamed
Jemni, a computer scientis at the School of Science and Technology in Tunisia.
