Free-hand mobile messaging-method and device
View Patent ↗A communication system and device that enables free-hand drawn SMS (Short Messaging Service) messages to be transmitted and received from/to various user devices. A buffer device is inserted within a GSM compatible handset providing a buffer for both conventional SMS messages created by typing a message on the keypad of the handset and for free-hand drawn SMS messages created by drawing or writing the free-hand message on a data entry device. An optional OCR (Optical Character Recognition) facility can be provided in either the buffer device inserted within the handset or in a network server that receives the transmitted message and processes it for proper routing to the intended recipient.
1. A communication device comprising:
a master microprocessor;
a security identity module operably connected to the master microprocessor through a bus;
a buffering device operable to communicate with said master microprocessor;
a character recognition device operable to recognize handwritten characters provided in a first message and convert the handwritten characters into text,
wherein said master microprocessor is operable to receive said first message from the buffering device or the security identity module;
wherein said buffering device is operably connected to the bus between the master microprocessor and the security identity module;
wherein each of the master microprocessor and the buffering device is capable of controlling the character recognition device, and
wherein the communication device is a handset, and transmits said first message, with said text therein, via a communication network;
a receiving portion operable to receive a second message in a form of a standard SMS message; and
a conversion device operable to convert said second message into a freehand drawn message.
2. A communication device as set forth in claim 1 , wherein said buffering device comprises:
a quantizer operable to transform said first message into a collection of quantized messages.
3. A communication device as set forth in claim 1 , wherein said bus is defined by GSM (Global System for Mobile Communication) standard 11.11.
4. A communication device as set forth in claim 1 , wherein said communication device is compatible with GSM (Global System for Mobile Communication) standards.
5. A communication device as set forth in claim 1 , wherein said communication device is a GSM (Global System for Mobile Communication) telephone.
6. A communication device as set forth in claim 1 , wherein said communication device is a PDA (Personal Digital Assistant).
7. A communication device as set forth in claim 1 , wherein said communication device is a wireless device.
8. A communication device as set forth in claim 1 , further comprising:
a message entry device operable to provide said buffering device with said first message in a form of a free-hand drawn message entered by a user with said message entry device.
9. The communication device as set forth in claim 1 , comprising:
wherein said buffering device is further operable to receive said first message in a form of a standard SMS message input on the communication device and a free-hand created message input using a free-hand compatible data entry device.
10. A communication device as set forth in claim 2 , wherein said buffering device further comprises:
a memory module operable to store said first message; and
an encoder operable to encode said first message prior to transmitting said first message.
11. A communication device as set forth in claim 8 , wherein said message entry device comprises:
a free-hand writing area in which said first message can be entered.
12. A communication device as set forth in claim 8 , wherein said first message comprises handwritten text, hand-drawn pictures, or both.
13. The communication device as set forth in claim 9 , wherein said free-hand created message can be transmitted as an SMS message, a facsimile message or an e-mail message.
14. A communication device as set forth in claim 10 , wherein said buffering device further comprises:
a decoder operable to decode received messages.
15. A communication device as set forth in claim 11 , wherein said message entry device further comprises:
a create portion operable to place said communication device in a freehand message entry mode when activated; and
a save portion operable to store said first message into said buffering device.
16. A communication device as set forth in claim 12 , wherein said message entry device comprises:
a text included portion operable to notify the master microprocessor that an optical character recognition function should be performed on said first message; and
a language portion operable to notify the master microprocessor that the optical character recognition facility to be performed is different than a default language associated with the communication device.
