Apple去年发布的iphone，结合大屏幕，多点触摸，和虚拟键盘等技术开创了触摸屏手机的新时代。而最近曝光的nokia一系列关于触摸技术的专利表明，该公司要让手机不“摸”也能用。

新的专利里，首先包含了一套和苹果的屏幕触摸技术类似的系统，包括单手操作，双手操作，和手势操作等等方面，完整定义了一套操作规范。

Single finger based Gestures/commands

Clockwise, counter clockwise circular rotations - browsing, scrolling listing applications
Subsequent typing by a single finger (Tap1-Tap2…) - activate device/phone, run/execute pre-selected option
Finger stays motionless (over certain time treshold) above some object/icon - select object/icon
Finger stays above some item/object/icon, followed by slow movement - select object till end of the move
Crossed perpendicular lines (X mark) - Delete
Perpendicular moving breach (Check mark) - Accept/Verify
Enclosed Curve around group of items - Select enclosed items

Two finger based Gestures/Commands

Linear approaching/digression (fingers approach, then move apart, and vice versa) - Zoom In/Out, size adjustment
Simultaneous touching of an icon/object by two fingers - Select the icon/object ready for size adjustment
Simultaneous tapping by two fingers (Tap 1&2, Tap 1&2, repeated) - High level importance Acceptance & Verification
Onefinger stays above an icon/object then object specific menu appears;the other finger performs circular rotations and toggles through themenu options, lifting simultaneously both fingers up selects andexecutes menu option

Compound Gestures/Commands

COPY=SELECT + Check mark inside (performed in vicinity of selected item)
CUT= SELECT + X mark inside
PASTEis based on COPY assuming that an indicator of the clipboard content isvisible on screen after COPY, then one TAP on clipboard may createPASTE command and paste content at the pointer of pre-selcted item/icon

同时在专利当中，nokia还展示了一个集成在手机上的复杂三维空间影响和模式识别系统，可以对手机周围的一个空间里的用户虚拟操作进行定位和运动识别。以便用户不“摸”手机就可以对手机进行完整的操作控制。

Three or more transducers (14 A-B-C in picture above) arrayed around aperimeter of the mobile device create a 10-20 cm working volume ofspace above the display, where user finger ( 20A and B) locations andtheir movements in real time can be detected using triangulationtechniques. These movements can then be interpreted as various threedimensional gestures.
To ease the operation of the device, visual finger pointers (12A, B) are displayed on the screen of mobile device.
3D gestures are translated into various object oriented, orgesture/browsing oriented commands. The patent application givesseveral examples.
Object oriented commands:

Select:- Picking up gesture - Finger 1 at a display corner or some reservedarea, Finger 2 moves slowly under a displayed object to be selected
Copy: - when selected, click by single finger on the object
Paste: - fast double click by a single finger
Move: - move slowly two fingers located on moving objects
Delete: - double (fast) click by two fingers on previously selected object
Switch:- switching (on/off) is based on change in directions of fingersmovement or, alternatively, on a change in finger acceleration

Gesture/browsing oriented commands:

Select object attributed to the pointer position: Open/closed hand
Forward/Backward Browsing: anticlockwise/clockwise cyclic rotation by a single finger
Zoom in/Out: expand/close two fingers
Run/Execute pre-selected icon/command: make a circle with your thumb and pointing finger (an OK sign)
