While there are a large number of ways to interpret and play back MIDI data on your computer using any number of hardware and software devices, there is only one way to use MIDI to render a project in ACID. On the Track Header for MIDI tracks, the track must be routed through the Master device, which is the DirectX SoftSynth that ACID uses internally to process MIDI data. Click the Device Selection button (the Bus Selection button on audio tracks—see Figure 10.2) to see the list of available devices. The specific device that is available is set up on the Audio tab in the Preferences dialog box (see Figure 10.2). 

To simplify user input we have applied a simple menu based interface. A back, forward and select button are presented on the PDA screen and can be felt by the user via a raised paper control panel overlaying the touch screen. This allows controls to be shaped differently and therefore be easier to identify than using the inbuilt buttons on the PDA, or using the keypad of a smart phone device. However we must still identify how well this interface will scale when more functions are added. 

Clicking this button opens the Printer Setup dialog box through which the user can select the output device from a list of all devices known to the MS-WINDOWS operating environment. 

If necessary select the Printer Setup... button and setup your printing device. 

Choose the Page Setup... option in the Output pull-down menu and select the plotting parameters and projections to be included in the plot. Adjust the sizes of all windows (title, parameter, spectrum) to the size of the paper sheet. Set up a title and select the parameters to be plotted. Load the defined levels with the Load button, choose different colors for the levels if you have a multicolor output device. Click the Preview button to inspect the final layout in the Preview window. Repeat these steps, load the defined levels with the Load button as before, but add additional contour levels with the Fill button. 

Use again the 2D magnitude mode H/ H COSY spectrum D NMRDATA GLUCOSE 2D HH GHHCO 001999.RR and switch to the Stacked display mode. Select a region of interest. Use the Grid button in the button panel and the mouse to move and tilt the 3D spectrum according to your ideas. Set up your output device and plot the expanded COSY spectrum in stacked display mode. 

The next tab is usually the Driver tab (Figure 13.31). This tab allows you to see the driver name for the device as well as the driver version, if available. You can see in the figure that no drivers have been loaded for this device, or the drivers specified for the device are not compatible. If you need to load a driver (or update a driver), click the Update Driver button. Windows 9x will present you with a list of drivers to select from or allow you to install your own from floppy disk or CD-ROM. If you have upgraded to Windows 98 from Windows 95, you may find that a number of updated Windows 98 drivers are available on vendor Web sites. 

A small example will illuminate this setting. Users that participate in a collaborative session in an immersive VE are usually tracked and use mouselike input devices that provide six degrees of freedom and additional buttons for specific commands that can be used to interact with the system. As stated above, the collaborative part of this setting is that more than one user interact in the same shared virtual world. That means that all users have access or at least the possibility to interact with the presented objects at the same time, usually with a mouse-like device, gestures or speech recognition. E.g., the system detects the push of a button on the 3D-mouse over a virtual object and utters an event to the application that has then the possibility to interpret the push of the button over the object as a try to select that object for further manipulation, e.g., dragging around. In a different implementation, the user application does not see the push of the button as such, but is presented an event that indicates the selection of an object within the world and can react on that. 

The usual input device is a keyboard which may contain 90 or more keys. For the novice computer user, simply finding the correct key can be a daunting task, so alternative input devices have been developed. These include touch-sensitive screens, tracker balls, light pens and so on. Perhaps the most common alternative to the keyboard is the mouse. This is simply a small box with one or more buttons on the top and a tracker ball on its underside. The mouse is connected to the computer via a single cable. As the mouse is moved over a flat surface, sensors detect the movement of the ball and the computer can calculate the position of the mouse. An arrow or similar symbol is usually displayed on the screen and this symbol moves in synchrony with the mouse. The mouse can be used to move the symbol to indicate choices on the screen and these can then be selected by pressing one of the buttons on the mouse. While experienced computer-users sometimes complain that mouse-based... 

Technology has also become a tool that can be used to conduct training beyond the basic use of PowerPoint LaRose (2009) presents the value of integrating audience response systems into training sessions. Audience response systems utilize a handheld device commonly referred to as a clicker to gauge audience response to various questions. For example, a multiple choice or true/false question can be presented on a PowerPoint slide. Each trainee in the room will have a clicker that can be used to press a button that selects the response that they believe to be correct. In addition to clickers, smartphone applications can be used to convert the phone into a clicker. The trainer can then immediately present the response to the question. This tool can be used innovatively in training to include such applications as... 

Although the discussion so far has concentrated on devices that perform interlocking and trip functions, inputs to the control system processing unit are commonly in the form of signals from selection switches, push buttons and other devices. There is a huge range of such devices and, as far as safety is concerned, it will simply be noted that these devices are commonly used to implement start, stop and mode selection functions. 

In SONAR, from the Options menu, select MIDI Devices. In the MIDI Ports dialog, on the Inpnt Ports list, select 1 Sonic Fonndry MIDI Router (single click it to highlight it) and click the OK button. 

Hardwired ESD activation means have traditionally been a push-in knobs or buttons. These devices have been subject to false activation as individuals can inadvertently lean on them and cause activation. Such buttons are usually protected with a cover that an individual has to physically lift in order to allow the button to be pushed in. Alternatively, buttons are available that have to be pulled out in order to activate the signal. Both of these selections require a confirmed action for the ESD activation to prevent false activation by an operator. AH devices should only be manually resettable. 

While the InterCUBE selection is done by rotating the device the mouse selection is done by moving the device over the selected option and clicking the mouse left button. To allow for a fair comparison, we have set the distance between the options in the mouse system to be such that the time for mouse displacement should be approximately the same than an average rotation of the InterCUBE. Within the menu structure, options have consistent and identical positions on the display. The option at the top of the display is always used to go back, and the option at the bottom, when applicable, is used as a confirmation of choice. Left and Right options are used for choices, and when not available are simply not displayed. Both menus are identical and have a maximum of four options located at the top, bottom, right and left of the display.
