3 SMART QUILLIs a pen that can remember the words that is used to write, and then transform them into computer text.
4 HISTORY Lyndsay Williams of Microsoft Research's Cambridge UK lab is the inventor of Smartquill.Smart Quill, has been developed by research laboratories run by British Telecom at Martlesham,England.User can use any platform for writing like paper, screen or even air.
7 DISPLAY TECHNOLOGY Technology used for display is Kopin Corp Cyber Display technology.Cyber Display is a ¼ inch diagonal LCD that uses circuitry built on a silicon wafer
8 HAND WRITING RECOGNITION AND SIGNATURE VERIFICATION Accelerometers measure hand movement in 2 or 3planesOn board DSP converts to ASCII characters for pen applicationsWrite on paper, flat surface, vertical wall or in airSingle character recognition on penRecord cursive letters and download to PC for decodingPassword by signature recognition
9 Display scrolls by Tilting Screen By tilting the pen, user can choose applications and scroll through without using scroll buttons.
10 COMMUNICATION WITH OTHER DEVICES The data stored in the memory is uploaded to the personal computer when it is placed into a docking station.The output accelerometer signals from the pen are digitized with a National Instrument capture card with a frequency Fe of 1000Hz and a low pass filter at Fc=1/3*Fe.Future models could receive s and pager messages via a wireless messaging system .This enables two-way wirelesscommunication with other computing devices
11 PROTOTYPE OF SMARTQUILL This Smart Quill prototype records writing on paper for radio transmission to a pocketpc,desktop,cellphone or tablet computer.The pen will power down after a period of no movement so doesn’t need an on/off switch .
12 MEMORY It has 4MB EEPROM memory. At a time, up to10 pages of notes can bestored locally on the pen.It works by measuring the pen'smovements and matching them to themovements that produce letters and wordsprogrammed into its memory
13 Power Is powered by AAA battery. It will run for about 25hours on a single AAA battery.
14 APPLICATIONS 1.It is all space-age. It contains an ink cartridge so that users can see what they write onpaper .2. The information stored in the pen can be inputto other devices such as mobile phones, printers,modems, desktop computers etc for differentapplications.3. It also provides handheld computer applications such as digital diary, contacts, calculators etc.
15 4. It is used for receiving pager and e-mail messages. 5. It synchronizes files, s and messages to PC.6. It can be used for voice record and supports speech recognition.7. It also allows third party to add on applications.
16 ADVANTAGES 1. One of the major asset is that it does not need a screen to work. This is possible through revolutionary "Spatial Sensing"system which uses semiconductor accelerometers.2. It provides intuitive user interface.3. It enables handwriting recognition .User can train the pen to recognize particular handwriting style.
17 4. It is also a 3D-mouse, when twisted in air in a certain way it enables scrolling of the screen. It also automatically detects left or right handed use.5. Power savinga. Small screen size requires less battery power.b. No movement of the pen causes auto power down6. It is all mobile, smaller in size and enablesone-handed use.
18 CONCLUSION Smart Quill was brought to the market in the end of 2006.The estimated cost of this futuristic pen isaround $600.SmartQuill supports two factors : smallsize and convenient use. The future of Smart Quillensures all computation power the user needs rightinside the pen. Reducing the size of handheldcomputers can only be taken so far before theybecome unusable. Keyboards become so tiny yourequire needle-like fingers to operate them andscreens that need constant cursor controls to readsimple text. The introduction of Smart Quill is the best solutionfor this problem.
