Direct Interaction with Large Displays Through Monocular Computer Vision
DIRECT INTERACTION WITH LARGE DISPLAYS THROUGH MONOCULAR COMPUTER VISION A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in the School of Information Technologies at The University of Sydney Kelvin Cheng October 2008 © Copyright by Kelvin Cheng 2008 All Rights Reserved Abstract Large displays are everywhere, and have been shown to provide higher productivity gain and user satisfaction compared to traditional desktop monitors. The computer mouse remains the most common input tool for users to interact with these larger displays. Much effort has been made on making this interaction more natural and more intuitive for the user. The use of computer vision for this purpose has been well researched as it provides freedom and mobility to the user and allows them to interact at a distance. Interaction that relies on monocular computer vision, however, has not been well researched, particularly when used for depth information recovery. This thesis aims to investigate the feasibility of using monocular computer vision to allow bare-hand interaction with large display systems from a distance. By taking into account the location of the user and the interaction area available, a dynamic virtual touchscreen can be estimated between the display and the user. In the process, theories and techniques that make interaction with computer display as easy as pointing to real world objects is explored. Studies were conducted to investigate the way human point at objects naturally with their hand and to examine the inadequacy in existing pointing systems. Models that underpin the pointing strategy used in many of the previous interactive systems were formalized. -

WIMP Interfaces for Emerging Display Environments
Graz University of Technology Institute for Computer Graphics and Vision Dissertation WIMP Interfaces for Emerging Display Environments Manuela Waldner Graz, Austria, June 2011 Thesis supervisor Prof. Dr. Dieter Schmalstieg Referee Prof. Dr. Andreas Butz To Martin Abstract With the availability of affordable large-scale monitors and powerful projector hardware, an increasing variety of display configurations can be found in our everyday environments, such as office spaces and meeting rooms. These emerging display environments combine conventional monitors and projected displays of different size, resolution, and orientation into a common interaction space. However, the commonly used WIMP (windows, icons, menus, and pointers) user interface metaphor is still based on a single pointer operating multiple overlapping windows on a single, rectangular screen. This simple concept cannot easily capture the complexity of heterogeneous display settings. As a result, the user cannot facilitate the full potential of emerging display environments using these interfaces. The focus of this thesis is to push the boundaries of conventional WIMP interfaces to enhance information management in emerging display environments. Existing and functional interfaces are extended to incorporate knowledge from two layers: the physical environment and the content of the individual windows. The thesis first addresses the tech- nical infrastructure to construct spatially aware multi-display environments and irregular displays. Based on this infrastructure, novel WIMP interaction and information presenta- tion techniques are demonstrated, exploiting the system's knowledge of the environment and the window content. These techniques cover two areas: spatially-aware cross-display navigation techniques for efficient information access on remote displays and window man- agement techniques incorporating knowledge of display form factors and window content to support information discovery, manipulation, and sharing. -

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. -
Enriching the Desktop Metaphor with Physics, Piles and the Pen
Enriching the Desktop Metaphor with Physics, Piles and the Pen by Anand Agarawala A thesis submitted in conformity with the requirements for the degree of Master of Science Graduate Department of Computer Science University of Toronto © Copyright by Anand Agarawala 2006 Abstract Enriching the Desktop Metaphor with Physics, Piles and the Pen Anand Agarawala Master of Science Graduate Department of Computer Science University of Toronto 2006 We explore making virtual desktops behave in a more physically realistic manner by adding physics simulation and using piling instead of filing as the fundamental organizational structure. Objects can be casually dragged and tossed around, influenced by physical characteristics such as friction and mass, much like we would manipulate objects in the real world. In addition we explore giving icons the affordances of paper supporting crumpling, creasing and pinning up to the walls for annotation. To manipulate and browse piles we integrate advances in techniques and propose our own novel set. We present a prototype, called BumpTop, that coherently integrates a variety of interaction and visualization techniques optimized for pen input we have developed to support this new style of desktop organization. Encouraging results of a user evaluation are also presented in which participants were able to complete 88% of tasks and find the interface enjoyable and satisfying. i Acknowledgements During my time at the University of Toronto, I developed in a few ways. I moved away from home, matured and grew up a little, gained some intellectual capacity, gained some pounds and my first grey hairs, gained the affectionate nickname “crispy”, gained several friends through a multitude of good times, infamously embarrassed myself, got to meet some interesting people like Master T and be in the proximity of others (Rick Mercer, Naomi Klein, JRS-One), and had my ego destroyed and rebuilt numerous times. -
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. -

Direct Pen Interaction with a Conventional Graphical User Interface
HUMAN–COMPUTER INTERACTION, 2010, Volume 25, pp. 324–388 Copyright © 2010 Taylor & Francis Group, LLC ISSN: 0737-0024 print / 1532-7051online DOI: 10.1080/07370024.2010.499839 Direct Pen Interaction With a Conventional Graphical User Interface Daniel Vogel1 and Ravin Balakrishnan2 1Mount Allison University, Sackville, New Brunswick, Canada 2University of Toronto, Ontario, Canada We examine the usability and performance of Tablet PC direct pen input with a conventional graphical user interface (GUI). We use a qualitative observational study design with 16 participants divided into 4 groups: 1 mouse group for a baseline control and 3 Tablet PC groups recruited according to their level of experience. The study uses a scripted scenario of realistic tasks and popular office applications designed to exercise standard GUI components and cover typical interactions such as parameter selec- tion, object manipulation, text selection, and ink annotation. We capture a rich set of logging data including 3D motion capture, video taken from the participants’ point-of-view, screen capture video, and pen events such as movement and taps. To synchronize, segment, and annotate these logs, we used our own custom analysis software. We find that pen participants make more errors, perform inefficient movements, and express frustration during many tasks. Our observations reveal overarching problems with direct pen input: poor precision when tapping and dragging, errors caused by hand occlusion, instability and fatigue due to ergonomics and reach, cognitive differences between pen and mouse usage, and frustration due to limited input capabilities. We believe these to be the primary causes of nontext errors, which contribute to user frustration when using a pen with a conventional GUI.
