A problem in smart environments is the interaction with a myriad of different devices, in particular the selection which of the devices should be controlled. Typically, different devices require ...different control tools. In contrast, a generic Point & Click appliance is proposed. To interact with a device in the environment this generic control appliance is pointed at devices for selection providing visual feedback to the user, obtains control information from the device, and allows control with the help of a simple user interface.
In this chapter, matrix application to tissue samples with the ImagePrep device is explained. The operating principle of vibrational vaporization of the matrix solvent and gravitational deposition of ...the droplets is presented. An important feature of the device is the control of the deposition process with an optical sensor; the principle of this detection is described. The chapter includes an introduction to the simple user interface with the adjustment of wetness, incubation time, and matrix thickness as intuitive parameters. A brief introduction to method development possibilities for detailed control over the matrix deposition process is given.
The simplest user interface might consist of a window with a few buttons or check boxes on the screen. However, there’s a limit to the number of options you can cram inside a window. Eventually, you ...may want to organize commands in categories and display those categories of commands in pull-down menus at the top of the screen.
Using these wizard-built buttons and the technique of opening and closing forms of carefully chosen dimensions, it’s possible to put together an attractive and useable front-end to your database, ...tailored to the needs of your users. The user interface described above, so far as it goes and with all its imperfections, is in the chap20end.mdb file.
