## Trackpad Multitouch (Indirect manipulation)
### Gesture Types
> [<img alt="image"
> src="/user-experience/multitouch/GesturesImages.png">](/user-experience/multitouch/GesturesImages.png)
* 1 finger: traditional pointing
* 2 finger: traditional scrolling
* 3 finger horiz.: three fingers in a row (usually ring/middle/index)
* 4 finger horiz.: four fingers in a row (usually
pinky/ring/middle/index) - may be hard to disambiguate horizontal
swipes on small trackpads, so we will overlap many gestures with the
three finger variants
* 1 finger edge: one finger moving in and out of the trackpad bounds
* May require hardware support.
* Vertical gestures may be problematic because of limited space.
* 3 finger group: three fingers in a circle (usually
thumb/middle/index \[or ring\])
* Due to people resting their thumb on the trackpad, many of these
gestures are problematic, particularly pinch and rotate
gestures. Swipe gestures are generally pretty usable.
* 4 finger group: four fingers in a circle (usually thumb +
ring/middle/index)
* Problematic as above. Swipe gestures are acceptable.
### Proposed behaviors
> #### Main view
* **one finger** — cursor
* **two** fingers — content manipulation
* Sites can override all two finger gestures passed to the
content area
* Pinch - defaults to page zoom
* Rotate - defaults to nothing
* Translate - defaults to scroll
* **three** fingers horizontal
* tab switch
* **three** fingers up — into overview
* **three** fingers down — focus panels
* **four** fingers up — into overview
* **four** fingers down — focus panels
* **four** fingers horizontal — window switching
* **three** finger group translate — back/forward or tab switch
(reverse of horizontal's behavior)
* **three** finger group rotate — problematic because of two
finger with anchored thumb
* **one** finger left/right edge in — back/forward
* **one** finger left/right edge out — forward/back, or sidebar
reveal
* **one** finger top edge in — overview
* **one** finger bottom edge in — panels
> #### Overview
* **two** fingers horizontal — switch tabs
* **two** fingers up/down? — close tab
* **three** fingers — switch windows
* **four** fingers — window switching
* **three** fingers down — out of overview
* **four** fingers down — out of overview
* **three** or **four** fingers up — logout
> #### Panels
* **two** fingers = scroll current panel
* **three** fingers horizontal = switch panels
* **three** fingers up = back to main view
## Full Multitouch (Direct manipulation)
* All content area gestures (two and one finger) passed directly to
web pages
* Default behaviors for one and two finger gestures as above
* We may reserve the above 3/4 finger gestures for os needs:
* three fingers — window movement/resizing
* four fingers — overview
