1. MouseSpeedV Introduction (Version 1.03 for Vista)

MouseSpeedV provides a number of ways to enable the user to change the mouse cursor control gain within the context of a game, or any other application. The program runs in parallel with the game. The mouse gain can be changed using either speech input, or buttons beneath the LCD on the Logitech G15 keyboard. You can also turn on/off mouse acceleration.

Speech input is processed using the Microsoft Speech Application Programming Interface (SAPI 5.3), and it uses the build in SR engine that ships with Vista.

Requirements

- Headset (for speech input, audio feedback)

- Logitech G15 LCD (for auxiliary display device)

- Windows Vista (which includes the .NET 2.0 Framework)

Files

The application consists of a number of files. Originally these were embedded in the application, but I got requests for different WAV files, optional LCD support, different spoken commands, etc.

File	Description
MouseSpeedV.exe	main program executable
DTMF-1-9s.wav	wave file played when increasing gain
DTMF-9-1s.wav	wave file played when decreasing gain
Interop.SpeechLib.dll	interface to speech recognition
lgLcdLibWrapper.dll	interface to Logitech G15 LCD
lgLCDNETWrapper.dll	interface to Logitech G15 LCD
MouseSpeedGrammar.xml	spoken commands to increase/decrease gain
MouseSpeedV.xml	program settings, including preset gains

2. Using the Program

High gain settings offer the possibility for rapid initial coarse movement towards a target, but this can result in difficulty with respect to making precise movements required to select the target at the end of the move sequence. Conversely, use of a low gain setting can result in slower initial movement, but improved precise positioning in target selection at the end of the move.

In many games there will be no single “optimal” gain setting; rather there is potential benefit to be achieved by the user having to ability to dynamically change it depending on the game situation e.g. depending on the zoom level, or current weapon selection, etc.

There are two distinct categories of cursor gain adjustment that the player may require:

- Experimentation: During the early stages of game play the player may want to make adjustments to cursor gain to determine their preferred setting for different game scenarios. This typically involves the user making small adjustments to the cursor gain, followed by their subjective evaluation of performance using that new cursor gain setting.

- Preset Switching: When the player becomes more familiar with the game and their controller the player may want to quickly switch between known gain presets for different game play situations e.g. higher gain setting for coarse target selection, lower gain setting for precision target selection.

User Interface Elements

Item	Description
	Option to play some sounds when the mouse gain is changed
	Option to display program information on the Logitech G15 LCD
	The currently selected recognizer
	The currently select audio input device
	Details of the last successful spoken command recognition
	The audio level VU meter
	If checked then the “next” and “previous” commands move between presets, otherwise these commands increment and decrement the mouse gain in steps of one.
	Reflects the state of the “Enhance Pointer Precision” checkbox in mouse control panel

Spoken Commands

Command	Description
Mode	Toggle between preset and experimentation modes.
Next	Next: Increase the gain by one, or move to the next preset gain
Previous	Decrease the gain by one, or move to the previous preset gain
Precision	Toggle “Enhance Pointer Precision” checkbox in mouse control panel

Editing the Gain Presets File

Presets are stored in the "MouseSpeedV.xml" file. You can edit this text file to change presets as you like.

Speech Recognition

A few notes on the speech recognition elements of the program:

The default Windows XP recognizer, unless trained, returned very spurious results for spoken speech. The Vista engine seems much more accurate and robust.

When Vista was released I changed the program to use in “in process” recognizer, so as not to interfere with the built-in operating system functionality which uses a “shared process” recognizer.

Ensure the language ID (control panel) for your system matches the default speech recognizer (speech recognition control panel), and these match the LANGID attribute in the “mousespeedgrammar.xml” file. There are grammar files for American English (*809.xml) and (*409.xml) in the package. So depending on the setting of the user account you have logged in to on Vista you might need to:

COPY MouseSpeedGrammar-409.xml MouseSpeedGrammar.xml

COPY MouseSpeedGrammar-809.xml MouseSpeedGrammar.xml

if you see the following dialog box when the program starts
