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)

更进一步的是，为了解决屏幕键盘空间窄小的问题，专利里还出现了一种虚拟键盘投影技术，用户可以在手机周围虚空投影的一个“空间键盘”上虚拟操作，而识别系统把结果反映在屏幕上和操作者进行互动。

这些技术到底是什么样子，也许3GSM2008上 NOKIA会有相关的发布和说明。

这样的话，手机用哪支手拿？

把空间键盘投影在正面不就行了，我猜哈
