1. GenTrans Technology Technical Presentation QWERTY Compact Keyboard

2. Introduction QWERTY Compact™ keyboard is designed for a mobile personal computer. The goal of this development is to create a new standard small-size keyboard for mobile devices that implements the localized layouts as in a standard-size computer keyboard. Also, nowadays, when every person uses mobile devices, it is a clear necessity to modify the QWERTY layout which was initially intended (the basic layout for a modern computer keyboard was invented by Christopher Sholes in 1868) for typing by two hands on a typewriter so that it should be fitted for holding in one hand and typing on it by the other hand. This requirement is critical for the effectiveness of communication and mobile computing.

3. Specification Figure 1 shows a layout of the QWERTY Compact™ keyboard. The system of typing is as following: The first column of keys of the alphabetic part of the keypad is intended for the index finger, the second and third columns - for the middle finger (which is positioned over the central vertical line of the keypad) and the fourth column – for the ring finger. The Space key is pressed by the index finger. The thumb is used for pressing key combinations. This method is applied when you hold the device by the other hand. Fig. 1

4. The main concept of this project is to create a keypad that is fully functional to meet the specifications of a standard computer keyboard for typing in different languages. That means if you compare them the combinations of characters on the buttons are identical and the numbers of the buttons with the characters are the same. It provides a full localization for other alphabet systems (e.g. for the Cyrillic alphabet shown on the draft). When the localized layout is selected, the characters from the numeric keypad placed on the buttons with the additional letters and by default typed directly and using the Shift key are pressed using the Alt and Ctrl keys accordingly (for additional punctuation marks.,: in the localized layout – using the Shift and Alt keys).

5. The central ring is used for positioning of cursor and selection when it is pressed and held along with the Ctrl key. The keyboard layouts are switched using Alt+ Shift keys combination. Also, by default, the following designations are used: F1 - Help, F2 - Call Manager, F3 - Mail, F4 – Browser ; Quick Keys (optional) - Ctrl, Alt, Shift+ Enter (center key); Ctrl, Alt + Backspace key and also not assigned keys from the alphabet and numeric keypads; Home - Shift+ F1, End - Shift+ F2, Change Case - Shift+ F3, Esс - Shift+ F4; Delete – Shift+Backspace

6. Start of Document - Ctrl+ F1, End of Document - Ctrl+ F2, Page Up - Ctrl+ F3, Page Down - Ctrl+ F4; Character Left Extend - Shift+ Left, Character Right Extend - Shift+ Right, Word Left Extend - Alt+ Left, Word Right Extend - Alt+ Right; Paragraph Up Extend - Ctrl+ Left, Paragraph Down Extend - Ctrl+ Right, Insert Page Break – Ctrl+Space, Insert Column Break – Alt+Space, Start of Doc Extend - Alt+ F1, End of Doc Extend - Alt+ F2, Pause - Alt+ F3, Close Window - Alt+ F4; Caps Lock – Shift+Tab, Undo - Ctrl+ Z, Select All - Ctrl+ A, Select Whole Word – double-clicking with Enter key, Copy - Ctrl+ C, Paste - Ctrl+ V, Cut - Ctrl+ X, Taskbar - Alt+ Tab, Program Menu - Ctrl+ Tab, Task Manager – Ctrl+Alt+Space.

7. Mobile Device Design The first of the prototype models using QWERTY Compact™ keyboard has a mobile notebook design (Fig. 2). The case of the device has dimensions – 55 x 98 mm (display size – 2,8’’, 240x320 pixels). The practical implementation of the device could involve the use of sensor technologies for achieving more reliable and thinner design. Fig. 2

8. Fig. 3Fig. 4 The device construction could involve various mobile TV, video, audio and networking solutions. For example, it implements a videophone mode with the second display (Fig. 3) and a digital camera mode with a rotatable main display (Fig. 4).

9. The second mobile PC prototype has a solid monoblock construction with the keyboard hidden inside emerging like an automatic drawer. It has the three separated parts - display, motherboard with a keyboard and battery with a camera (Fig. 5). The case of the device has dimensions – 58 x 104 mm (display size – 3’’, 240x320 pixels). Fig. 5

10. Fig. 7 And the third mobile PC model is a “double slider” that additionally to an ordinary slider form factor has a possibility to mount a detachable display (Fig. 6) on the case in a landscape mode (Fig. 7). The display works as a separated Bluetooth device and could be a light- weight phone itself when the case is set somewhere around. Fig. 6

11. Conclusion The QWERTY Compact™ keyboard layout is fully functional for working as a computer keyboard and could be the base for a standard mobile keyboard specification. The layout includes a standard phone numeric keypad “as it is” and there is no need to switch between the alphabetic and numeric keypads as it’s been implemented in the most of the existing models. And as the most important feature, the QWERTY Compact™ keyboard design allows the developers completely integrate the localized layouts of a standard computer keyboard and that is the crucial thing for being chosen by the customers around the world. Therefore, the mobile PC prototype models using the QWERTY Compact™ keyboard described in this presentation are comfortable in use devices which would implement a great majority of the state-of-the-art mobile computing and consumer electronics technologies.
