  A Breakdown of the Psychomotor Components of Input Device Usage
Devices that allow faster primary movement results in a less accurate primary movement and lead to a greater distance travels in secondary movement phase.
The most efficient devices are less constrained by the “speed accuracy/tradeoff” allowing users to move at a higher optimal velocity, without increasing the chance of error.
This is consistent with the SOS model prediction that movements are made to optimize performance by limiting the effect of motor noise and suggest input devices should be designed to limit the effect of noise in the interaction between the user and the input device.

 General Input Device Emulating Interface
Therefore, once the AAC device is connected to the computer as shown in Figure 1 (e.g., either directly through the use of a serial cable or indirectly via some kind of wireless link), something must act as a "go-between" to translate the AAC device language into the keyboard or mouse language understood by the computer.
Since the fl box is connected between the standard input devices and the computer, it understands the language used by the keyboard and mouse when talking with the computer, and is therefore capable of allowing the AAC device to again "emulate" the standard input devices.
Since many of the alternate input devices today require the user to program these escape sequence strings in "squares" or "selections" on their alternate input device, user readability was given greater priority than device memory requirements.

Input device is on and running: Device is receiving full power from its power source, delivering full functionality to the user, and preserving applicable context and state information.
This is recommended because a user typically uses an input device of some kind to wake the system when it is in a power management state (for example, when the system is sleeping).
The actual input data (particular button or key pressed) that's associated with a wake event should never be discarded by the device itself, but should always be passed along to the policy owner or other software for further interpretation.

 Technical Note TN2091: Device input using the HAL Output Audio Unit
If the channels of the device format and the desired format do not have a 1:1 ratio, the AUHAL unit can use channel maps to determine which channels to present to the user.
For obtaining input from a device, the device format is always expressed on the input scope of the AUHAL's Element 1.
For example, we have a 4-channel device that we are using for input, but we only desire channels 2 and 3 of the device for stereo input.

 Vibration sensing touch input device patent invention
The present invention provides a touch sensitive input device that uses vibrations due to touch impacts and/or frictional movement of a touch implement across a surface to determine information related to the touch, such as touch position.
The action of touching the input surface of the plate generates an impulse of energy whose bandwidth and amplitude depend on the contact material (finger, stylus, glove, etc.), the plate material (glass, acrylic, etc.), and the strength of contact.
The energy input at the contact point propagates to the vibration sensors and the location is calculated in much the same way as for the initial impact of the touch.
