System and method for differentiating between incoming and outgoing messages and identifying correspondents in a TTY communication
A method and system are provided that examine incoming and outgoing TTY transmissions to determine an identifier for distinguishing between correspondents in a TTY call. The system may utilize existing contact information associated wit an incoming call to provide context to a user for accepting incoming calls and during conversations and may apply various display settings. For TTY users, the additional context simplifies the ability to conduct critical reasoning, especially those with cognitive impairments. In particular, a picture from the user's address book is provided to assist in identifying the caller. The other display settings may include modified font styles, colors, multi-line display etc. to differentiate between incoming and outgoing messages.
1. A method for distinguishing between correspondents in a teletypewriter (TTY) call on a mobile device providing access to at least a first communication line configured to receive TTY calls, said method comprising:
examining an incoming or outgoing TTY transmission associated with said TTY call;
determining an identifier in said TTY transmission associated with a respective correspondent participating in said TTY call, said correspondent being said mobile device for outgoing TTY transmissions and being an other party for incoming TTY transmissions;
for incoming TTY transmissions, comparing said identifier to data stored in an address book on said mobile device and, if said other party is found in said address book, accessing at least a portion of said data; and
using said identifier to identify said respective correspondent by displaying said at least a portion of said data on a display screen provided by said mobile device with text associated with said TTY call.
2. The method according to claim 1 wherein said at least a portion of said data is a picture associated with said other party.
3. The method according to claim 1 wherein said examining occurs upon receiving an originating TTY transmission from said other party and said modifying said display comprises displaying said at least a portion of said data in an incoming call screen.
4. The method according to claim 1 wherein said at least a portion of said data is a picture associated with said other party and said modifying said display comprises displaying said picture in a TTY conversation screen for the duration of said TTY call.
5. The method according to claim 1 wherein said modifying said display comprises differentiating text in incoming and outgoing TTY transmissions according to one or more display settings.
6. The method according to claim 5 wherein said one or more display settings comprise an option for specifying any one or more of the following settings in combination: font type, font style, font size, case, and colour.
7. The method according to claim 5 wherein said one or more display settings comprise an option for separating said text in incoming and outgoing TTY transmissions using line breaks.
8. The method according to claim 5 wherein said one or more display settings comprise an option for identifying said text in incoming and outgoing TTY transmissions by displaying a name for said respective correspondent.
9. A computer readable storage medium comprising computer executable instructions for: distinguishing between correspondents in a teletypewriter (TTY) call on a mobile device providing access to at least a first communication line configured to receive TTY calls, said computer executable instructions comprising instructions for:
examining an incoming or outgoing TTY transmission associated with said TTY call;
determining an identifier in said TTY transmission associated with a respective correspondent participating in said TTY call, said correspondent being said mobile device for outgoing TTY transmissions and being an other party for incoming TTY transmissions;
for incoming TTY transmissions, comparing said identifier to data stored in an address book on said mobile device and, if said other party is found in said address book, accessing at least a portion of said data; and
using said identifier to identify said respective correspondent by displaying said at least a portion of said data on a display screen provided by said mobile device with text associated with said TTY call.
10. The computer readable storage medium according to claim 9 , wherein said at least a portion of said data is a picture associated with said other party.
11. The computer readable storage medium according to claim 9 wherein said examining occurs upon receiving an originating TTY transmission from said other party and said modifying said display comprises displaying said at least a portion of said data in an incoming call screen.
12. The computer readable storage medium according to claim 9 wherein said at least a portion of said data is a picture associated with said other party and said modifying said display comprises displaying said picture in a TTY conversation screen for the duration of said TTY call.
13. The computer readable storage medium according to claim 9 wherein said modifying said display comprises differentiating text in incoming and outgoing TTY transmissions according to one or more display settings.
14. The computer readable storage medium according to claim 13 wherein said one or more display settings comprise an option for specifying any one or more of the following settings in combination: font type, font style, font size, case, and colour.
15. The computer readable storage medium according to claim 13 wherein said one or more display settings comprise an option for separating said text in incoming and outgoing TTY transmissions using line breaks.
16. The computer readable storage medium according to claim 13 wherein said one or more display settings comprise an option for identifying said text in incoming and outgoing TTY transmissions by displaying a name for said respective correspondent.
17. A mobile device comprising a display, an input device, a processor and a memory storing a computer readable TTY application providing access to at least a first communication line configured to receive TTY calls, said mobile device storing computer executable instructions for distinguishing between correspondents in a teletypewriter (TTY) call by:
examining an incoming or outgoing TTY transmission associated with said TTY call;
determining an identifier in said TTY transmission associated with a respective correspondent participating in said TTY call, said correspondent being said mobile device for outgoing TTY transmissions and being an other party for incoming TTY transmissions;
for incoming TTY transmissions, comparing said identifier to data stored in an address book on said mobile device and, if said other party is found in said address book, accessing at least a portion of said data; and
using said identifier to identify said respective correspondent by displaying said at least a portion of said data on a display screen provided by said mobile device with text associated with said TTY call.
18. The mobile device according to claim 17 wherein said at least a portion of said data is a picture associated with said other party.
19. The mobile device according to claim 17 wherein said examining occurs upon receiving an originating TTY transmission from said other party and said modifying said display comprises displaying said at least a portion of said data in an incoming call screen.
20. The mobile device according to claim 17 wherein said at least a portion of said data is a picture associated with said other party and said modifying said display comprises displaying said picture in a TTY conversation screen for the duration of said TTY call.
21. The mobile device according to claim 17 wherein said modifying said display comprises differentiating text in incoming and outgoing TTY transmissions according to one or more display settings.
22. The mobile device according to claim 21 wherein said one or more display settings comprise an option for specifying any one or more of the following settings in combination: font type, font style, font size, case, and colour.
23. The mobile device according to claim 21 wherein said one or more display settings comprise an option for separating said text in incoming and outgoing TTY transmissions using line breaks.
