based on the lack of detection of the persistent contact within the defined location, causing one or more actions to occur including changing a display on the computing device to a locked state, displaying a message indicating the operation of the machine is paused, and providing at the computing device a vibration or audio alert to indicate the operation of machine has paused.

8. The method of claim 1 , wherein the GUI enabling the computing device to control the operation of the machine is further based on the computing device and the machine exchanging communications at regular intervals to maintain a heartbeat.

9. The method of claim 1 , wherein the other touch inputs are indicative of instructions for the machine to perform one or more actions.

10. A non-transitory computer readable medium having stored thereon instructions that, upon execution by a computing device, cause the computing device to perform functions comprising:

displaying a pattern on a touchscreen of a computing device that includes a graphical user interface (GUI) for enabling control of an operation of a machine;

receiving an input gesture on the touchscreen of the computing device, the input gesture including movement along the pattern on the touchscreen from a first location of the pattern to a second location of the pattern; and

the GUI enabling the computing device to control the operation of the machine based on:

an authentication of the input gesture, and

detecting persistent contact within a defined location on the touchscreen, wherein the defined location includes the second location,

wherein the computing device is configured to display on the touchscreen, based on the authentication of the input gesture, boundaries for input of contact that qualifies as the persistent contact within the defined location,

wherein an operating system of the computing device is configured to:

interpret touch input for the persistent contact within the defined location,

enable the computing device to control the operation of the machine,

provide control of the operation of the machine to an application of the computing device in response to the authentication of the input gesture and detecting the persistent contact within the defined location, and

based on a lack of detection of the persistent contact within the defined location, disable control of the operation of the machine by the computing device by locking the touchscreen and returning the touchscreen to an initial state requiring the authentication of the input gesture, and

wherein the application of the computing device is configured to:

distinguish the touch input for the persistent contact within the defined location from other touch inputs representing contact outside of the defined location, and

using the other touch inputs for controlling the operation of the machine while detecting the touch input for persistent contact within the defined location.

11. The non-transitory computer readable medium of claim 10 , wherein the functions further comprise:

based on the lack of detection of the persistent contact within the defined location on the touchscreen, sending instructions to the machine to perform a specific function.

12. The non-transitory computer readable medium of claim 10 , wherein the functions further comprise:

determining that the touch input for the persistent contact is lacking for about 1-2 seconds; and

responsively pausing the operation of the machine.

13. The non-transitory computer readable medium of claim 10 , wherein the GUI enabling the computing device to control the operation of the machine is further based on the computing device and the machine exchanging communications at regular intervals to maintain a heartbeat.

14. The non-transitory computer readable medium of claim 10 , wherein the other touch inputs are indicative of instructions for the machine to perform one or more actions.

15. A system comprising:

a computing device including a touchscreen, an operating system, an application, and a graphical user interface (GUI) for enabling control of an operation of a machine;

one or more processors; and

data storage including instructions executable by the one or more processors to cause the system to perform functions comprising:

displaying a pattern on the touchscreen;

receiving an input gesture on the touchscreen of the computing device, the input gesture including movement along the pattern on the touchscreen from a first location of the pattern to a second location of the pattern; and

the GUI enabling the computing device to control of the operation of the machine based on:

an authentication of the input gesture, and
