Bulletin No.PMY10013 PMY10013 2010/07/01 PenMount Drivers Enhance Your Touch System Touch screens have become the most popular technology in recent years. Because touch control is for users to operate their systems in a intuitive manner, it is therefore much more satisfactory than any other input type that exists. However, since it concerns user's intuitive inputs, the accuracy and stability of a touch screen are strictly demanded. PenMount touch control solution holds full functionality and high quality and is also provided with specifically developed drivers that realizes user's intuitive inputs. The linearity of a resistive touch screen deteriorates as it is used as time passes. When the linearity gets really bad, the accuracy of a touch screen is crippled. To fix such problem, PenMount drivers are developed with a calibration program that effectively enhances the accuracy of a touch screen. Although touch screen calibration is supported by various popular Operating Systems (such as Microsoft Windows Embedded CE for 5-point calibration and QNX for 3-point calibration), only small extend of rectification can be made by the native calibration programs of these O.S, while PenMount's Calibrate presents the calibration modes of 4-, 9-, 16-, and 25-point that are applicable for the touch screens of various linearities. Aside from the linearity calibration feature, Edge Compensation is also made available by PenMount. Edge Compensation enables driver to automatically locate the touched positions around the edges of a touch screen while the touch screen's accuracy won't get damaged by the bad linearity at these areas, so that users can easily select any graphic icons on screen that appears adjacent to touch screen's edges to invoke any program. Hence Edge Compensation particularly serves the O.S. of Microsoft Windows, in which the Taskbar is occasionally hidden by default and needs user's touch at the edge to be displayed. The Edge Compensation featured by PenMount drivers comes in handy in such situation. Another feature of PenMount drivers is the Beep Sound. For example, someone operating an ATM with touch screen trying to transfer money might not know if he/she has done all he/she has to do to complete the transfer. If there is an audio feedback to help him/her confirm, he/she won't mistake and will be able to save troubles. Then again, the Beep Sound of PenMount drivers can be put to use for such purpose. PenMount drivers enable system buzzer or audio speaker of alert sound while the timing, length, and frequency of the alert sound to be given off are configurable. However, there is one note that this alert sound feature varies depending on the O.S. that you're using. Taking the buzzer for example, in Microsoft Windows Vista 64 bit and in Windows 7, buzzer isn't supported. It is recommended that you use audio speaker for sounding device if you're using either of the said two O.S. If you need to view or operate the touch screen in other orientations, PenMount drivers offer the orientation support of ATI, nVIDIA and intel's display chips. Your touch on the screen will be correctly located. Moreover, if there should be any special requirement coming from customers, such as setting up a physical button and have the screen orientation executed through pressing such button, PenMount team is also pleased to discuss with you about the implementation. All of the functions mentioned above are also included in the PCI touch solution that PenMount is going to launch soon. Although the projected capacitive touch screen in fact doesn't need any calibration of linearity, the other functions with PenMount drivers will still greatly enhance your touch system. PenMount series of touch software and hardware are designed to meet market demands. If customized specifications are needed, we are always ready and available to help customer to complete their project.
