Human‐computer interaction in 3D object manipulation in virtual environments: A cognitive ergonomics contribution Doctoral Thesis submitted to the Université de Paris‐Sud 11, Orsay Ecole Doctorale d'Informatique Laboratoire d'Informatique pour la Mécanique et les Sciences de l'Ingénieur (LIMSI‐CNRS) 26 November 2010 By Sarwan Abbasi Jury Michel Denis (Directeur de thèse) Jean‐Marie Burkhardt (Co‐directeur) Françoise Détienne (Rapporteur) Stéphane Donikian (Rapporteur) Philippe Tarroux (Examinateur) Indira Thouvenin (Examinatrice) Object Manipulation in Virtual Environments Thesis Report by Sarwan ABBASI Acknowledgements One of my former professors, M. Ali YUSUF had once told me that if I learnt a new language in a culture different than mine, it would enable me to look at the world in an entirely new way and in fact would open up for me a whole new world for me. I have found what he had said to be entirely true. So this was one of the things which had motivated me to look for a scholarship in a country, where the primary language of communication was not English (or for that matter, any of the other local South‐Asian languages that I learnt as a child), and hence I am here today writing my thesis in France. More concretely, this research was made possible through a contract between Higher Education Commission (HEC) and the French Embassy in Pakistan. While HEC funded most of my research for which I am grateful; the French Embassy arranged for us (me and certain other selected scholars) to learn and discover the French language and its culture by means of immersive language courses as well as arranging visits to different parts of the country before the commencement of academics. My interactions with the different people that I have met in France as well as the exploration of its different cities and regions has enabled me to enrich myself personally, academically, and culturally. This research came into being as a result of a meeting that was held between me and Michel DENIS, who has become my thesis director at LIMSI‐CNRS at the Université Paris‐Sud 11 (Orsay). Since that time and up until now, it would not have been possible to carry on, had it not been for the help provided to me by him on a continual basis. He has always been there whenever I have needed him for his intervention in the capacity of my aid, be it administrative or academic. He has gone beyond the normal limits, in helping me out with progressing farther, even when sometimes I had thought that it was beyond my limits, though his aid was not limited just to encouraging me only. He responded to my emails most promptly, and always gave invaluable, timely, and relevant feedback whenever I had needed it. This was indeed extraordinary. Michel, I really thank you for that. ii Object Manipulation in Virtual Environments Thesis Report by Sarwan ABBASI I was lucky enough to have gotten a chance to work under the direct supervision of Jean‐ Marie BURKHARDT, my co‐director, and with whom I also shared the same work‐place at the Université Paris Descartes. Whether at his office desk or at lunch table, he provided me with invaluable academic feedback on a continual basis and helped me learn and generate new ideas whenever I had needed them, and made me see things from a fresh point of view. I cannot thank him enough, for other than giving me useful advises throughout my research, he also ensured that I had enough resources for my personal sustenance especially towards the end of my thesis. No research takes place in isolation and without the interaction and/or help from a vast variety of people and my research is not an exception to that. The most critical portion of the technical facilities and assistance was provided by the VENISE team at the LIMSI‐CNRS lab at Université Paris‐Sud 11 (Orsay). I would primarily like to thank Patrick BOURDOT, who is also the director of VENISE, who kindly accepted to let his virtual reality room and other facilities at his lab be used for my research. I cannot possibly thank him enough for accepting to help me, as a major part of my research would not have been possible without it. In addition to just the place and equipment, I was also helped by various other people of the VENISE team, including Pierre MARTIN, Damien TOURAINE and Jean‐Marc VEZIEN, without whose help also, the experiments in the virtual setting would not have materialised. In particular, Pierre MARTIN helped me extraordinarily, to make my underlying ideas about the virtual puzzle (especially the interactions part) come to life. I cannot thank him enough for the devoted and untiring effort that he put in for me. I am grateful to Françoise DETIENNE and Stéphane DONIKAN for agreeing to be reviewers of my thesis. They provided me feedback and suggestions which proved very valuable for me and which are reflected in the current version of the thesis. I am also thankful to Philippe TARROUX and Indira THOUVENIN who graciously accepted to be the examiners of my thesis. There are many other people that I would like to thank, who have helped me in one way or the other, and I will probably not be able to name them all here. They appear here in no iii Object Manipulation in Virtual Environments Thesis Report by Sarwan ABBASI particular order: my former colleague Rami AJAJ (researcher in graphics), a former student and an internee at Université Paris Descartes, Gosia TARASEWICZ (ergonomist), internee Adrien SCHWARTZ (ergonomics student) and Karin HEIDLMAYR (psychology student). I am thankful also to many friends and family members, particularly Safdar Abbas KHAN, Sohail IQBAL, Issa ABBASI, Tjaša NABERGOJ, Marie‐Laure LE GUEN, Asim ARIF and Taj KHAN, who helped me at different times and in different ways, whether their help was in the form of brain‐storming, typing, proof‐reading, giving ideas when I got stuck, or in the form of giving helpful advices and encouragement. I thank also all the people who graciously accepted to participate in my experiments and without whom this research would also not have been possible. Last but not the least, I would like to thank my colleagues Julien NELSON, Cécile GIRARD, Amel Ben AYED, Sophie CAPO, Jeannine BOURDEAUX, Katarina BOHACOVA and Stanislas COUIX, who helped me at different times and in different ways with my research work, as well as with my personal development. It is perhaps impossible to name everyone, and I am sure there would still be a lot of people whose names I have forgotten, and for which I sincerely apologise in advance. iv Object Manipulation in Virtual Environments Thesis Report by Sarwan ABBASI Executive Summary It is proposed to investigate the cognitive processes involved in assembly/disassembly tasks, and then to apply the findings to the design of 3D virtual environments (VEs). Virtual Environments are interactive systems that enable one or more users to interact with the simulation of objects and scenes usually in three dimensions, in a realistic fashion, by means of a set of computational techniques covering one or more sensory modalities (vision, touch, haptic, hearing, etc.). Often described as the ultimate direct manipulation interface, this technology seeks to make the interface eventually ‘disappear’ in order to provide users with a ‘natural’ mode of interaction. Virtual reality (VR) is the experience of being within a VE. One objective of the VR technology is indeed to exploit natural human behaviour without requiring any learning from their users [Fuchs2003], [Bowman2005]. Moreover, VEs are a stimulating field of research because they involve perceptually and cognitively novel situations [Burkhardt2003]. VEs also offer a large potential of innovative solutions to existing application problems. Among others, assembly tasks are a major focus for VEs [Boud2000], [Brooks1999], [Lok2003‐a], [Lok2003‐b], due to their numerous potential applications, such as assembly/disassembly of objects, scientific research (e.g., molecular docking [Ferey2009] etc.). The common feature in VEs is the use of representations and devices to support the users in handling and arranging several distinct elements in a three dimensional (3D) space under specific constraints. Most of the current devices and interaction techniques have focused on providing users with high‐fidelity sensory stimulations, rather than targeting real‐life or task‐centred functions associated with the corresponding interfaces. While many contributions have been made to the field of VR, there are only few empirical data that have been published. We believe that it is very unlikely that more adapted VEs and assistance to users’ task – in the specific context of assembly tasks – will follow either just by chance [Brooks1999], by making repeated trials, by tuning what we already have at hand, or v Object Manipulation in Virtual Environments Thesis Report by Sarwan ABBASI by more realistic sensory renderings, without any reference to the ‘specific properties of the tasks’ including its cognitive dimension.

Frank David Barner Stanford University University of California, San Diego Mental abacus (MA) is a system for performing rapid and precise arithmetic by manipulating a mental representation of an abacus, a physical calculation device. Previous work has speculated that MA is based on visual imagery, suggesting that it might be a method of representing exact number nonlinguistically, but given the limitations on visual working memory, it is unknown how MA structures could be stored. We investigated the structure of the representations underlying MA in a group of children in India. Our results suggest that MA is represented in visual working memory by splitting the abacus into a series of columns, each of which is independently stored as a unit with its own detailed substructure. In addition, we show that the computations of practiced MA users (but not those of control participants) are relatively insensitive to verbal interference, consistent with the hypothesis that MA is a nonlinguistic format for exact numerical computation.

  • Project Design: Tetris
    Project Design: Tetris Prof. Stephen Edwards Spring 2020 Arsalaan Ansari (aaa2325) Kevin Rayfeng Li (krl2134) Sooyeon Jo (sj2801) Josh Learn (jrl2196) Introduction The purpose of this project is to build a Tetris video game system using System Verilog and C language on a FPGA board. Our Tetris game will be a single player game where the computer randomly generates tetromino blocks (in the shapes of O, J, L, Z, S, I) that the user can rotate using their keyboard. Tetrominoes can be stacked to create lines that will be cleared by the computer and be counted as points that will be tracked. Once a tetromino passes the boundary of the screen the user will lose. Fig 1: Screenshot from an online implementation of Tetris User input will come through key inputs from a keyboard, and the Tetris sprite based output will be displayed using a VGA display. The System Verilog code will create the sprite based imagery for the VGA display and will communicate with the C language game logic to change what is displayed. Additionally, the System Verilog code will generate accompanying audio that will supplement the game in the form of sound effects. The C game logic will generate random tetromino blocks to drop, translate key inputs to rotation of blocks, detect and clear lines, determine what sound effects to be played, keep track of the score, and determine when the game has ended. Architecture The figure below is the architecture for our project Fig 2: Proposed architecture Hardware Implementation VGA Block The Tetris game will have 3 layers of graphics.

  • Roles of Semantic Structure of Arithmetic Word Problems on Pupils’ Ability to Identify the Correct Operation
    ROLES OF SEMANTIC STRUCTURE OF ARITHMETIC WORD PROBLEMS ON PUPILS’ ABILITY TO IDENTIFY THE CORRECT OPERATION J ustin D. V ale nt in and Dr Lim Chap Sam (University of Science Malaysia) December,Dec em ber , 20042 004 Abstract This paper draws on findings from a study conducted in seven primary schools in Seychelles about pupils’ proficiency in one-step arithmetic word problems to discuss the roles of semantic structures of the problems on the pupils’ ability to identify the operation required to solve them. A sample of 530 pupils drawn from Primary 4, 5 and 6 responded to a 52 multiple choice item test in which they were to read a problem and select the operation that is required to solve it. The results showed some consistencies with other international studies in which pupil related better to additive than to multiplicative problems. Moreover, they could solve better those problems that do not involve relational statements. The general picture indicated that there is an overall increase in performance with an increase in grade level yet, when individual schools are considered this increase in performance in significant in only one school. In the other results there were many cases of homogenous pairs of means. Analysis of distractors conducted on the pupils’ responses to the seventeen most difficult items reveal that in most cases when an item required the operation indicating an additive or multiplicative structure, the most popular wrong answer would be one of the same semantic structure. Otherwise there is a strong tendency for the pupils to select the operation of addition when they could not identify the correct operation for a particular problem.

DESCRIPTORS Arithmetic; *Division; Elementary Education; *Elementary School Teachers; Higher Education; 'Mathematics Instruction; Preservice Teacher Education; *Questioning Techniques IDENTIFIERS Mathematics Education Research; *Preservice Teachers; Problem Posing; Situated Lep.rning; *Subject Content Knowledge ABSTRACT Previous research has suggested that many elementary school teachers have a firmer understanding of addition and subtraction concepts than they have of more complex topics in elementary mathematics, such as division. In this study, (n=24) prospective elementary teachers' understanding of aspects of division involving remainders was explored by examining the problems they posed. The tea-:hers' responses revealed a clear preference for posing problems associated with real world contexts, suggesting that the term "story problem" had that particular meaning for this group. Although the vast majority of problems were situated in contexts, the problems and solutions frequently did not represent a solid connection between the mathematical and situational aspects of the problem. About two-thirds of the subjects spontaneously posed problems and proposed solutions that reflected their understanding of the relationship between the given computation and at least one member of its family of associated computations.

  • Arithmetical Development: Commentary on Chapters 9 Through 15 and Future Directions
    ARITHMETICAL DEVELOPMENT: COMMENTARY ON CHAPTERS 9 THROUGH 15 AND FUTURE DIRECTIONS David C. Geary University of Missouri at Columbia The second half of this book focuses on the important issues of arithmetical instruction and arithmetical learning in special populations. The former repre- sents an area of considerable debate in the United States, and the outcome of this debate could affect the mathematics education of millions of American children (Hirsch, 1996; Loveless, 2001). At one of the end points of this debate are those who advocate an educational approach based on a constructivist philosophy, whereby teachers provide materials and problems to solve but allow students leeway to discover for themselves the associated concepts and problem-solving procedures. At the other end are those who advocate direct instruction, whereby teachers provide explicit instruction on basic skills and concepts and children are required to practice these basic skills. In the first section of my commentary, I briefly address this debate, as it relates to chapters 9, 10, and 11 (by Dowker; Fuson and Burghardt; and Ambrose; Baek, and Carpenter respectively). Chapters 12 to 15 (by Donlan; Jordan, Hanich, and Uberti; and Delazer; and Heavey respectively) focus on the important issue of arithmetical learning in special populations, a topic that has been largely neglected, at least in relation to research on reading competencies in special populations. I discuss these chapters and related issues in the second section of my commentary. In the third, I briefly consider future directions. Instructional Research (Chapters 9 to 11) Constructivism is an instructional approach based on the developmental theories of Piaget and Vygotsky (e.g., Cobb, Yackel, & Wood, 1992).

  • Tetromino Reptiles
    Mathigon – Lesson Plan Tetromino Reptiles Standards Prior knowledge NC Key Stage 3: Use scale factors, scale diagrams and maps It will help if students have some familiarity with expressing relationships CCSS 7.G.A.1: Solve problems involving scale drawings of using ratio, and with square numbers. geometric figures Lesson outline This task uses Polypad’s tetrominoes as a context for exploring enlargements (dilations) and scale factors. Tetrominoes are shapes which can be made from 4 individual squares, and will be instantly recognisable to any student who has played the classic game Tetris. Lesson objective: Understand how the area of a shape changes when it is enlarged. Lesson activity Warm-up Show students this Polypad canvas. Explain that two of the tetrominoes have been enlarged (dilated) correctly, but two of them have mistakes. Invite students to work out the scale factor by which the two correct enlargements have been drawn, and to use the pen tool (or copy the diagrams onto squared paper) to correct the mistakes in the Canvas Link incorrect enlargements. Solution: The square has been correctly enlarged by a scale factor of 3, and the L tetromino has been correctly enlarged by a scale factor of 5. The T tetromino and the Z tetromino have not been enlarged correctly. If students haven’t seen tetrominoes before, and you think they could benefit from additional scaffolding before the warm up above, you could challenge them to find all the different arrangements of four 1-square tiles. They can use this canvas as a starting point. Main Activity Some shapes can be used to tile an enlargement of themselves – this is sometimes called a rep-tile.

  • Developing a Pedagogical Domain Theory of Early Algebra Problem Solving Kenneth R
    Developing a Pedagogical Domain Theory of Early Algebra Problem Solving Kenneth R. Koedinger Benjamin A. MacLaren March 2002 CMU-CS-02-119 CMU-HCII-02-100 School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213 Abstract We describe a theory of quantitative representations and processes that makes novel predictions about student problem-solving and learning during the transition from arithmetic to algebraic competence or "early algebra". Our Early Algebra Problem Solving (EAPS) theory comes in the form of a cognitive model within the ACT-R cognitive architecture. As a "pedagogical domain theory", our EAPS theory can be used to make sense of the pattern of difficulties and successes students experience in early algebra problem solving and learning. In particular, the theory provides an explanation for the surprising result that algebra students perform better on certain word problems than on equivalent equations (Koedinger & Nathan, 2000; Nathan & Koedinger, 2000). It also makes explicit the knowledge and knowledge selection processes behind student strategies and errors and provides a theoretical tool for psychologists and mathematics educators to both productively generate and accurately evaluate hypotheses about early algebra learning and instruction. We have abstracted our development process into six model-building constraints that may be appropriate for creating cognitive models of problem solving in other domains. This research was supported by a grant from the James S. McDonnell Foundation program in Cognitive Studies for Educational Practice, grant #95-11.

  • BOOK the Tetris Effect: the Game That Hypnotized the World
    Notes by Steve Carr [www.houseofcarr.com/thread] BOOK The Tetris Effect: The Game That Hypnotized the World AUTHOR Dan Ackerman PUBLISHER Public Affairs PUBLICATION DATE September 2016 SYNOPSIS [From the publisher] In this fast-paced business story, reporter Dan Ackerman reveals how Tetris became one of the world's first viral hits, passed from player to player, eventually breaking through the Iron Curtain into the West. British, American, and Japanese moguls waged a bitter fight over the rights, sending their fixers racing around the globe to secure backroom deals, while a secretive Soviet organization named ELORG chased down the game's growing global profits. The Tetris Effect is an homage to both creator and creation, and a must-read for anyone who's ever played the game-which is to say everyone. “Henk Rogers flew on February 21, 1989. He was one of three competing Westerners descending on Moscow nearly simultaneously. Each was chasing the same prize, an important government-controlled technology that was having a profound impact on people around the world . That technology was perhaps the greatest cultural export in the history of the USSR, and it was called Tetris . Tetris was the most important technology to come out of that country since Sputnik.” “Tetris was different. It didn’t rely on low-fi imitations of cartoon characters. In fact, its curious animations didn’t imitate anything at all. The game was purely abstract, geometry in real time. It wasn’t just a game, it was an uncrackable code puzzle that appealed equally to moms and mathematicians.” “Tetris was the first video game played in space, by cosmonaut Aleksandr A.
