Touchscreen technology is gradually becoming more popular and massive in our present society to the point where it is hard to find a person that has never used this interface system. Handheld devices such as mobile phones and tablets are predominantly based on touchscreens as the main way to interact with them. Nevertheless, that is not the case when it comes to personal computers either desktop machines or laptops which are still chiefly based on traditional keyboard and mouse as their main input system. In this study we explore the potential that touchscreen based interface can offer for personal computers carrying through an observational experiment with six participants that were asked to perform a list of tasks using both traditional keyboard-mouse interface and touchscreen interface. The measurements during the observation concerned time and error rate for every task. Each participant was interviewed right after the completion of the observational phase in order to get a qualitative insight on their views and perceptions regarding both interfaces. The data collected was analyzed based on some existing models within touchscreen interface and human-computer interaction that have been elaborated in previews research. The final results led to the conclusion, that touchscreen-based interface proved to be slower and have higher error rate than traditional interface in a big number of the tasks performed by the participants. Similarly, the general perception of the people towards having touchscreen on a personal computer still seems a bit doubtful, although they do see some concrete positive aspects about this interface. Nevertheless, touchscreen outperformed traditional interface in some particular tasks. This implies that touchscreen interface has a clear potential for personal computers that would let users utilize these machines in a much broader and more interactive way than people do it today with the traditional keyboard-mouse interface.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / The explosive use and extensive development of software and hardware for the IBM PC and PC Clones over the past few years has positioned the PC as one of many viable alternatives to system designers configuring systems for both data acquisition and data analysis. Hardware abounds for capturing signals to be digitized and analyzed by software developed for the PC. Communication software has improved to where system developers can easily link instrumentation devices together to form integrated test environments for analyzing and displaying data. Telemetry systems, notable those developed for lab calibration and ground station environments, are one of many applications which can profit from the rapid development of data acquisition techniques for the PC. Recently developed for the ADS100A telemetry processor is a data acquisition module which allows the system to be linked into the PC world. The MUX-I/O module was designed to allow the PC access to telemetry data acquired through the ADS 100A, as well as provide a method by which data can be input into the telemetry environment from a host PC or equivalent RS-232 or GPIB interface. Signals captured and digitized by the ADS100A can be passed on to the PC for further processing and/or report generation. Providing interfaces of this form to the PC greatly enhances the functionality and scope of the abilities already provided by the ADS100A as one of the major front-end processors used in telemetry processing today. The MUX-I/O module helps "bridge the gap" between telemetry and the PC in an ever increasing demand for improving the quantity and quality of processing power required by today's telemetry environment. This paper focuses on two distinct topics, how to transfer data to and from the PC and what off-the-shelf software is available to provide communication links and analysis of incoming data. Major areas of discussion will include software protocols, pre vs post processing, static vs dynamic processing environments, and discussion of the major data analysis and acquisition packages available for the PC today, such as DaDisp and Lotus Measure, which aid the system designer in analyzing and displaying telemetry data. Novel applications of the telemetry to PC link will be discussed.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The trend of current data acquisition and recording systems is to capture multiple streams of Pulse Code Modulation (PCM) data on a single media. The MARS II data recording system manufactured by Datatape, the Asynchronous Realtime Multiplexer and Output Reconstructor (ARMOR) systems manufactured by Calculex, Inc., and other systems on the market today are examples of this technology. The quantity of data recorded by these systems can be impressive, and can cause difficulties in post-test data processing in terms of data storage and turn around time to the analyst. This paper describes the system currently in use at the Strategic Systems Combined Test Force B-1B division to simultaneously post-flight process up to twelve independent PCM streams at twice real-time speeds. This system is entirely personal computer (PC) based running the Window NT 4.0 operating system with an internal ISA bus PCM decommutation card. Each PC is capable of receiving and processing one stream at a time. Therefore, the core of the system is twelve PCs each with decommutation capability. All PCs are connected via a fast ethernet network hub. The data processed by this system is IRIG 106 Chapter 8 converted MIL-STD-1553B bus data and Chapter 4 Class I and II PCM data. All system operator inputs are via Distributed Component Object Modeling (DCOM) provided by Microsoft Developers Studio, Versions 5.0 and 6.0, which allows control and status of multiple data processing PCs from one workstation. All data processing software is written in-house using Visual C++ and Visual Basic.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / A new kind of telemetry ground data system--Multi-Pulse PPK (Pulse Position Keying) Telemetry System Based on PC(MPPK-PCTS) is presented in this paper. Being Aimed at the lower bit rate which is the essential shortcoming of Single-Pulse PPK(SPPK), Multi-Pulse PPK(MPPK) signal is introduced to this system. Its signal forms, bit rate, energy efficiency and error probability have been analysed in detail. The symmetric Bi-Pulse PPK(BPPK) signal with fixed reference pulse can be practised in engineering. In this system, front-ends are intelligent and modular, all modules are integrated in a personal computer chassis through EISA/PCI bus. The system operates under multi-media WINDOWS environment, with intelligent user interface. Faults can be detected and located automatically. With flexible performance, good expandibility and small size, the system can be used in reentry telemetry and many other fields where higher rate and lower power are both required.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Due to the rapid advancement of technology in GUI design tools within Microsoft Windows™, a sophisticated human-machine interface can be developed for telemetry systems. A PC Windows™-based telemetry system would effectively provide a "bridge" between the telemetry world and the Windows™ world, bringing many low cost off-the-shelf software and hardware tools into the telemetry realm that has been unprecedented. This paper describes the results of such an approach in the development of Loral's Visual Telemetry System (VTS) software.
