Many smartphones support direct calling via motion control. With the direct calling function activated, if the display shows a specific contact or a message from a specific contact you only need to place your smartphone up to your ear to call this contact. Using motion and proximity sensors, the smartphone recognizes a connection is to be established and in this case uses the information on the screen to make the call.
The direct calling function is helpful for individuals in need of care or children unable to dial a specific number or execute an action on a phone. In this case, first a number is stored in the phone which will then be used for direct calling. With direct calling activated on the phone, this number is dialled automatically when the receiver is picked up or a key is pushed. This allows children to easily call their parents from their call phone without dialling the entire cell phone number or pushing a specific speed dial button. This feature is often referred to as baby call.
Smartphones can often be configured so that touching a picture of an individual will place a call to them. Children and persons in need of help can also use this function for direct calling.
