+# Automating mobile gestures
+
+While the Selenium WebDriver spec has support for certain kinds of mobile
+interaction, its parameters are not always easily mappable to the functionality
+that the underlying device automation (like UIAutomation in the case of iOS)
+provides. To that end, Appium implements the new TouchAction / MultiAction API
+defined in the newest version of the spec
+([https://dvcs.w3.org/hg/webdriver/raw-file/tip/webdriver-spec.html#multiactions-1](https://dvcs.w3.org/hg/webdriver/raw-file/tip/webdriver-spec.html#multiactions-1)).
+Note that this is different from the earlier version of the TouchAction API in
+the original JSON Wire Protocol.
+
+These APIs allow you to build up arbitrary gestures with multiple actuators.
+Please see the Appium client docs for your language in order to find examples
+of using this API.
+
+An unfortunate bug exists in the iOS 7.x Simulator where ScrollViews don't
+recognize gestures initiated by UIAutomation (which Appium uses under the hood
+for iOS). To work around this, we have provided access to a different
+function, `scroll`, which in many cases allows you to do what you wanted to do
+with a ScrollView, namely, scroll it!
+
+## Scroll
+
+To allow access to this special feature, we override the `execute` or
+`executeScript` methods in the driver, and prefix the command with `mobile: `.
+See examples below:
+
+* **WD.js:**
+
+```js
+// scroll the view down
+driver.execute("mobile: scroll", [{direction: 'down'}], function(err) {
+// continue testing
+});
+```
+
+* **Java:**
+
+```java
+JavascriptExecutor js = (JavascriptExecutor) driver;
+HashMap<String, String> scrollObject = new HashMap<String, String>();
+scrollObject.put("direction", "down");
+scrollObject.put("element", ((RemoteWebElement) element).getId());
+js.executeScript("mobile: scroll", scrollObject);
+```
+
+## Automating Sliders
+ 
+**iOS**
+ 
+ * **Java**
+ 
+```java
+// slider values can be string representations of numbers between 0 and 1
+// e.g., "0.1" is 10%, "1.0" is 100%
+WebElement slider =  wd.findElement(By.xpath("//window[1]/slider[1]"));
+slider.sendKeys("0.1");
+```
+ 
+**Android**
+
+The best way to interact with the slider on Android is with TouchActions.
+
+## Set orientation
+
+* **WD.js:**
+
+```js
+driver.setOrientation("LANDSCAPE", function(err) {
+// continue testing
+});
+```
+
+* **Python:**
+
+```python
+driver.orientation = "LANDSCAPE"
+```
