  • Gestural Interaction Design for Information Exchange Between Large Public Displays and Personal Mobile Devices
    SimSense: Gestural Interaction Design for Information Exchange between Large Public Displays and Personal Mobile Devices Jobin Mathew James University of Tampere School of Information Sciences Human-Technology Interaction M.Sc. thesis Supervisor: Prof. Markku Turunen Dec 2015 i University of Tampere School of Information Sciences Human-Technology Interaction Jobin Mathew James: SimSense - Gestural Interaction Design for Information Exchange between Large Public Displays and Personal Mobile Devices. M.Sc. thesis, 60 pages, 4 index and 11 appendix pages December 2015 Large displays in public and semi-public spaces continuously permeate our everyday lives as the price of display hardware continues to drop. These displays act as sources of information, entertainment and advertisement in public environments such as airports, hotels, universities, retail stores, hospitals, and stadiums, amongst others. The information shown on these displays often varies in form that ranges from simple text to rich interactive content. However, most of this rich information remains in the displays and methods to effectively retrieve them to ones’ mobile devices without the need to explicitly manipulate them remains unexplored. Sensing technologies were used to implement a use case, wherein a person can simply walk up to a public display, retrieve interesting content onto their personal device without having the need to take it out of their pockets or bags. For this purpose a novel system called SimSense, which is capable of automatically detecting and establishing a connection with mobile phones that come in close proximity with the public display was developed. This thesis presents two alternative mid-air hand gesture interaction techniques: ‘Grab & Pull’ and ‘Grab & Drop’ to retrieve content from the public display without explicitly operating the mobile device.

  • Stresscheck 10.1 2014
    StressCheck 10.1 2014 RELEASE NOTES JUNE 16, 2014 (BUILD 10615) This document summarizes the new features available in 64-bit StressCheck 10.1 Professional Edition. For more details, please refer to the Master Guide Addendum available in the main menu of StressCheck under Help. FILE MANAGEMENT SYSTEM The StressCheck file system was completely redesigned in version 10.1 to simplify, improve stability, and make its usage intuitive. The input file (*.sci) and database (*.scm) have been replaced with the StressCheck workfile (*.scw) and the StressCheck project (*.scp). The StressCheck project file (*.scp) is designed to be the default file format when saving and opening StressCheck data. This single file solution replaces the database (*.scm), associated files and its dataset folder. The StressCheck workfile (*.scw) replaces the StressCheck input file (*.sci). As solution data can significantly increase the file size of StressCheck projects, the workfile exists as a smaller alternative that does not contain solution data. It is a snapshot of the model in its current state. The most significant feature of the project file is that StressCheck does not write to it during a session unless the user selects the save option. All temporary files are kept in a separate location which can be changed by the user in the Options dialog. TLAP LOADING Several improvements were made in the way StressCheck handles imported TLAP points. The Status column of the Case Definitions window now reflects the current point assignment status for TLAP points. If a point is assigned in a load, the Status column is updated with “Assigned(x)” where the number in parenthesis (x) is the number of times the point has been assigned in a load record.

  • The Trackball, a Related Pointing Device, Was Invented in 1941 By
    The trackball, a related pointing device, was invented in 1941 by Ralph Benjamin as part of a World War II-era fire-control radar plotting system called Comprehensive Display System (CDS). Benjamin was then working for the British Royal NavyScientific Service. Benjamin's project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user with a joystick. Benjamin felt that a more elegant input device was needed and invented a ball tracker called "roller ball", for this purpose.[5][6] The device was patented in 1947,[6] but only a prototype using a metal ball rolling on two rubber- coated wheels was ever built, and the device was kept as a military secret.[5] Another early trackball was built by British electrical engineer Kenyon Taylor in collaboration with Tom Cranston and Fred Longstaff. Taylor was part of the original Ferranti Canada, working on the Royal Canadian Navy's DATAR (Digital Automated Tracking and Resolving) system in 1952.[7] DATAR was similar in concept to Benjamin's display. The trackball used four disks to pick up motion, two each for the X and Y directions. Several rollers provided mechanical support. When the ball was rolled, the pickup discs spun and contacts on their outer rim made periodic contact with wires, producing pulses of output with each movement of the ball. By counting the pulses, the physical movement of the ball could be determined. A digital computer calculated the tracks, and sent the resulting data to other ships in a task force using pulse-code modulation radio signals.
