" IIMIIIIIHIMM\nCENTRE FOR INTEGRATED COMPUTER SYSTEMS RESEARCH 'C'hC'S'R*\nTHE UNIVERSITY OF BRITISH COLUMBIA\nBuilding virtual environments with reality-based modelling\nDinesh Pai's research is breaking\nnew ground in real-time sound &\nobject deformation simulation\nIf virtual reality is to be more real than\nvirtual, then objects must not only look\nrealistic, but sound and feel realistic as well.\nDinesh Pai has taken on this challenge-the\nCICSR member's work in reality-based\nmodelling is helping to flesh out virtual\nenvironments, and to improve the feel of\nhuman-machine interfaces that require the\nreal-time simulation of remote or virtual\ninteractions.\n\"I want to build rich computational\nmodels of the physical world,\" says Pai, an\nassociate professor of Computer Science\nwho specializes in computational robotics.\n\"Models that are based on actual measure-\nments-this is the reality part-and that can\nsupport interactive simulation.\"\nExtending virtual reality\n\"The idea,\" explains Pai, \"is that, in the\nnear future, in any sort of virtual environment, you will not only see a 3d object, but\nalso be able to pick it up and feel it. And\nwhen you put the object down it will make\na realistic sound. You'll be able to interact\nwith these environments.\"\nThe realistic models and interfaces Pai\nand his team are creating will have an\nimpact on everything from computer games\nto training simulations to microsurgery.\nThe technology could also be used, for\nexample, in the remote assembly of\nindustrial components over the Internet.\nReality-based modelling starts with the\nmeasurement of real objects, and the\ncapture of contact feedback and audio\ncharacteristics. Pai is leading a team of\nfaculty, staff, and students that is developing\nACME, the Active Measuring facility. The\nteam includes students Doug James, Jochen\nLang, Derek Difilippo, Paul Kry and Josh\nRichmond.\nACME is an integrated system that\nincludes a robot arm to capture contact\ndata, a 5 degree-of-freedom field measurement system that measures the sound and\ncontinued on page 2\nc\nFall 1999 Vol. 10, No. 2\nSelf-test microchip 3\nAligning information systems 4\nImproved lumber grading 5\nBob Evans 6\nPassing Notes 7\nDistinguished Lecture Series 8 The academic year begins again,\nwhich means it is time for CICSR's\n1 lth annual Distinguished Lecture\nSeries. We have another great line-up\nof speakers, so be sure to read the\nposter that accompanies this issue of\nFOCUS. (The speakers and dates are\nalso found on page 8.)\nIn this issue we profile the\ninnovative work of four CICSR\nmembers. The common thread is\ntheir collaborative approach to\nresearch-many of them work in teams\nto solve their research problems.\nDinesh Pai is leading a team into\nvirtual territory; Peter Lawrence's\ngroup is improving sawmill performance; Yair Wand and Carson Woo\nare investigating the relationship\nbetween organizations and their\ninformation systems; and Andre\nIvanov is developing self-testing\nmicrochips.\nWe also pay a tribute to Bob\nEvans, who steps down as head of\nUBC's Mechanical Engineering\ndepartment. I have enjoyed working\nwith Bob in my role as CICSR\ndirector, and thank him for his\ncontributions over the years.\nLastly, don't forget to note that the\nNational Science Foundation's Year\n2000 conference will be held here in\nVancouver, January 3-6. CICSR\nmember Yusuf Altintas is co-chair of\nthe proceedings.\nRabab Ward, CICSR Director\nVirtual environment, continued from page 1\nlight field around an object, and a laser\nrange measurement system. The ACME\nsystem also permits remote modelling, so\nthat researchers can interact with ACME\nover the Internet.\nReal-time simulation\nWith measurements obtained through\nACME, Pai can then build accurate models\nof objects and their\ncharacteristics. He is\nparticularly interested\nin the real-time\nsimulation of the\nsounds and forces\nproduced by contact,\nsince these provide\nimportant perceptual\ncues for users\ninteracting with\nsimulated objects.\nOver the past 4\nyears, Pai and his\nteam have developed a framework for the\nsimulation of sounds caused by the contact\nor collision of physical objects in a virtual\nreality environment.\n\"The framework is based on the\nvibration dynamics of bodies,\" says Pai.\n\"The computed sounds depend on the\nbody's material, its shape and the contact\nlocation.\"\nThese simulated sounds give a user\nimportant auditory cues that lend a larger\nsense of reality to the objects in the virtual\nenvironment. Another important sense-cue\nis object deformation.\nIn recent years, huge advances in\nsimulating 3d objects have been made. But\nmuch of that work has focussed on the\nshape and texture of objects. And shape, as\nPai points out, is only the beginning.\n\"You want to know what an object feels\nlike,\" he says. \"If it's a soft object and you\npush on it, how does it behave?\"\nOne potential application of deformation simulation is surgical training. Medical\nDinesh Pai\nstudents could practise surgical procedures\non computer-modelled tissues that deform\nas students cut them with virtual scalpels.\nReal-time simulation of object deformation, however, is far more difficult than\nsound simulation because the act of\ndeforming an elastic object is computationally expensive. But one of Pai's\ndoctoral students, Doug James, has\ndeveloped a highly\nefficient method for\ndeformable object\nsimulation that was\npresented at\nSIGGRAPH this\npast August.\nIndustry support\nPai, who is a\npast ASI fellow,\nhas enjoyed steady\nindustry support.\nPartners include\nPoint Grey Research and International\nSubmarine in BC; Haptic Technology Inc.;\nMPB Technologies in Montreal; and\nVirtual Technologies in Palo Alto, Ca.\n\"They've been supporting us with their\nequipment,\" says Pai, noting that Virtual\nTechnologies has loaned his group\nCyberGloves, and Point Grey Research has\ncontributed trinocular stereo systems.\nInternational Submarine was interested\nin Pai's research because it builds robotic\narms for submarines and the Canadian\nspace agency. Now CICSR is trying to\ncombine that company's interest in\ntelerobotics with Pai's research in reality-\nbased modelling. And Virtual Technologies\nwants to see how deformable object\nsimulation can be plugged in with its\nCyberGlove.\n\"In a sense,\" says Pai, \"we are pioneering\nthese technologies.\"\nFor more information, contact Dinesh\nPai at pai@cs.ubc.ca or (604) 822-8197.\nFOCUS Self-test part of microchip revolution\nAndre Ivanov develops built-in self-test technology\nfor the next generation of microelectronic devices\nExponential growth in the complexity and\nfunctionality of microchips is the norm in\nthe microelectronics industry. Moore's Law\nstates that the number of transistors on a\nmicrochip doubles every 18 months. Today\nthere are 21 million transistors on a typical\nmicroprocessor chip; in 2012 the Semiconductor Industry Association predicts that\nnumber will grow to 1.4 billion.\nThis warp-speed growth creates enormous pressure on chip manufacturers, as\nmarket demand threatens to outstrip their\nability to design and test fault-free microchips and quickly bring them to market in a\ncost-effective manner.\nAndre Ivanov, an expert in integrated\nmicroelectronics engineering (IME) is\nhelping to relieve that pressure by developing IME test tools and techniques that will\nsave chip manufacturers time and money.\nBIST and SOC\nIvanov, a CICSR member and associate\nprofessor of Electrical and Computer\nEngineering, develops special circuits and\nCAD tools that verify digital, analog and\nmixed-signal circuits. His most recent work\nfocuses on new testing techniques such as\nbuilt-in self-test (BIST) and its use in\nemerging system-on-a-chip (SOC)\ntechnologies.\nMicrochip manufacturing is an imperfect process, and random defects are a\nreality. Testing is a vital step in the manufacturing process as it detect faults; but the\nautomatic testing equipment (ATE) that\nmanufacturers use to test chips is very\nexpensive to buy and run. And since chip\ndesigns change so quickly, manufacturers\nstruggle to keep testing technology abreast\nof microchip development while amortizing\ntheir current ATE investment.\n\"It's a losing battle,\" says Ivanov. \"Testers\nare required to verify and test state-of-the-\nart circuits\u00E2\u0080\u0094but how can they keep ahead\nof state-of-the-art when the testers are built\nfrom the same technology? It's a moving\ntarget.\"\n\"And it doesn't make sense for testing to\nbe more expensive than design and manufacture,\" adds Ivanov, a past ASI fellow.\nThis frustration was the impetus for\nBIST. Over the years, researchers have\nmulled over the possibility of self-testing\ncircuits that would eliminate the bottleneck\nand expense of ATE testing.\nBut chip designers, until recently, could\nnot afford to allocate any circuitry on their\nchips to a BIST function. With transistors\nnow numbering in the millions on a single\nchip, BIST functionality is today a practical\nreality.\nState-of-the-art testing\n\"A big advantage is that BIST allows for\nstate-of-the-art testing,\" explains Ivanov.\n\"By having the technology test itself, the\ntesting keeps pace with the latest developments in chip design.\"\nThis includes system-on-a-chip (SOC)\ntechnology, another focus of Ivanov's work.\nSOCs are portable miniature systems that\nfit on a single microchip. SOC applications\nrun the gamut from household appliances\nto life-critical, in-body devices such as\npacemakers or micropumps that regulate\nin-body medicine delivery.\n\"SOC is the enabling technology for\ntomorrow's systems,\" says Ivanov. \"But how\ndo you figure out what's wrong with a\nminiaturized microelectronic or\nmicromechanical system? You can't reverse\nengineer or diagnose it. That's why self-test\nand monitoring are so important.\"\nIvanov is currently developing a BIST\ncircuit that will monitor the power supply\nfor portable low-power devices.\n\"There's a demand for low-power\nelectronic gadgets with more and more\nfeatures,\" explains Ivanov. \"But battery\ncapacity has not kept pace with the\nevolution in electronics.\"\nThe BIST chip is designed to optimize\nbattery power and detect faults on- and offline. Ivanov hopes the chip will make\nelectronic devices more reliable and sees it\nas having particular utility in life-critical\napplications, such as pacemakers, where\npower supply monitoring is vital.\nNew areas of development\nTo Ivanov, BIST and SOC promise to\nopen new areas of microelectronics development. A chip in an automobile, for\nexample, could test itself and communicate\nthe resulting diagnostics to the manufacturer. Self-diagnosis could lead to self-\nrepair, an innovation that Ivanov believes\nwould usher in an era of ultra-reliable\nmicroelectronics-based systems.\n\"We're living a revolution,\" he says.\n\"Everything is going to be riding on SOCs.\nAnd if you build in self-testing, you can\nbuild the product correctly and cost-\neffectively and get it to market on time,\"\nsays Ivanov.\nIvanov has strong support from the\nmicroelectronics industry including\nCanadian Microelectronics Corporation,\nthe BC Advanced Systems Institute,\nMicronet, and PMC Sierra.\nAndre Ivanov can be reached at\nivanov@ece.ubc.ca or at (604) 822-6936.\nFall 99 Aligning\ninformation\nsystems with\nbusiness goals\nYair Wand and Carson Woo developed\na new method of object-oriented\nenterprise modelling and are using it\nto help organizations change during\ncompetitive times.\nMost organizations now depend on\ncomputers to automate business tasks such\nas order processing and customer billing.\nSophisticated computerization, however,\ncan create difficulties for organizations\nwhen it comes time for them to change or\n\"reengineer,\" an inevitable occurrence in\ntoday's competitive business environment.\nThe need to adapt existing systems can\nbecome an obstacle to successful change. As\nwell, organizations often acquire packaged\nsystems that do not fit well with their\nbusiness model, thus imposing system\nimplementation considerations on business\ndecisions. To Carson Woo and Yair Wand,\nthis is like putting the cart before the horse.\nUnique method\nWoo and Wand are associate members of\nCICSR and professors of Management\nInformation Systems (MIS) in the Faculty\nof Commerce. Their specialty is the use of\nmodels to support the analysis, design and\nconstruction of information systems (IS).\nDissatisfied with traditional methods of\nsystems analysis, they have developed a\nunique method of object-oriented enterprise modelling (OOEM) to help businesses\nalign their information systems with their\nbusiness goals.\n\"What we advocate is using the business\nmodel as a guide to developing information\nsystems,\" says Woo. \"Our overall goal is to\npromote a better fit between the business\nand its information systems, and to reduce\nthe time and resources needed to develop\ninformation systems.\"\nCarson Woo\nWand and Woo approach the problem\nby breaking it into three steps. First, they\nconstruct an organization's business model,\ni.e. a description of its mission, and\nproducts and services. Second, from the\nbusiness model, they derive the \"ideal\" IS\narchitecture. Third, they reverse-engineer\nexisting or proposed information systems\ninto the underlying business model by\nlinking existing system components to\nbusiness functions.\nTrue needs of an organization\nThis process enables them to conduct a\n\"match-gap\" analysis between the true\nneeds of the organization (as implied by the\nbusiness model) and pre-existing components (whether part of the current information systems portfolio or a new, proposed\npackage). This analysis can then be used to\nguide the adaptation process, to support\nreusability and to evaluate the appropriateness of new IS solutions.\nWand and Woo found that existing\nobject-oriented methods lacked precise rules\nfor modelling enterprises. Borrowing from\nontology, the branch of philosophy that\nconsiders models of reality, they derived a\nclearer definition for the role of objects in\nmodelling and a set of rules for constructing enterprise models.\n\"We have tested and improved OOEM\nover the last six years through instruction,\ngraduate research, and practical large-scale\napplication,\" says Wand. \"We have found\nYair Wand\nthe approach useful in constructing\nunambiguous, easy-to-understand models\nof both an enterprise and its IS architecture. \"\nThe new approach allows for an IS\nevaluation in terms of business needs and\nprocesses, rather than by an exhaustive\nexamination of system features. Shifting the\nfocus from IS details to the bigger business\npicture has the potential of making\ncompanies faster on their feet when it\ncomes to re-engineering business processes,\nintroducing new products and services, or\nmigrating to new information systems.\nObvious and essential\n\"People say later, 'it is so obvious we\nshould have thought about it sooner,'\" says\nWoo. \"What essentially matters is the\nbusiness rather than specific implementation details.\"\nWand and Woo have successfully applied\ntheir novel approach to companies in the\ntelecommunications and oil industries\nwhere competition and change is intense.\nWoo recently completed a sabbatical at\nBC Tel Mobility in Vancouver, BC, where\nhe introduced that company to the OOEM\napproach. He and Wand are hoping to\ngarner support from other companies who\nare beginning to show interest in their\nenterprise modelling method.\nYair Wand is at (604) 822-8395 and\nyair.wand@ubc.ca; Carson Woo is at\n(604) 822-8390 and carson.woo@ubc.ca\nFOCUS Speeding and improving lumber grading\nA CICSR team led by Peter Lawrence is working with CAE Newnes Ltd.\nto develop the latest generation of automated lumber grading systems\nThe next generation of automated lumber\ngrading machines will soon be on the job,\nthanks to a Precarn-supported project by a\nCICSR research team and its industrial\npartner.\nCICSR member Peter Lawrence is\nleading the UBC component of a team that\nis designing a more effective automatic\nlumber grading system along with CAE\nNewnes Ltd. of Salmon Arm, BC.\nCross-disciplinary team\nThe CICSR team is a cross-disciplinary\ngroup that draws on the talents of 7\nresearchers: Professors Lawrence from\nElectrical and Computer Engineering, Gary\nSchajer, from Mechanical Engineering,\nDave Barrett, of Wood Science, and Frank\nLam, also of Wood Science. The team also\nincludes Hossein Saboksayr, a CICSR\ngraduate student, Wilson Lau, a Wood\nScience graduate student, and Greg Grudic,\na consultant and former graduate student in\nElectrical and Computer Engineering.\nCAE Newnes is one of the world's\nleading manufacturers of automated\nsawmilling and woodprocessing equipment.\nThe company pioneered automated grading\nwith an x-ray system that sorted boards\nfaster and more accurately than the human\neye.\nBenefits of accurate grading\nFast, accurate board grading has two\nmajor benefits. It speeds wood processing\nand increases economic return by singling\nout strong, high-value boards. These boards\nare streamed into the fabrication of valuable\nproducts such as engineered beams and\ntrusses.\nNow the CICSR team is bringing\nlumber grading into the digital age by\ncombining advanced digital signal processing and microwave technology to improve\nthe x-ray system. The new system, which\nCAE Newnes plans to build and market,\nwill bring automated grading up to mill\nspeed while improving grading accuracy.\nThe system is designed to run unattended on a production line. As boards\ncome out of the sawmill they are bumped\ninto sequence past a scanner which uses\nsensors to measure each board for density,\nslope-of-grain and knot location. The\nmeasurements are then computed to make a\nstrength estimate of each board. This\nestimate is matched against a database that\nassigns the board its grade and finally prints\nit on the lumber.\nThe research team's major challenge is\ncombining accurate grading with high\nboard throughput. With sawmills running\nat speeds of up to 2,000 board feet per\nminute the system has to scan, analyze and\nmatch board data at a remarkable rate.\nTeam expertise\nThe team draws on the wide-ranging\nexpertise of its members to solve the\nproblem. Lam and Barrett contributed their\nknowledge of wood strength and mechanics, while Schajer's expertise in microwave\ntechnology and Lawrence's digital signal\nprocessing experience tackled the data\nanalysis side of the problem.\n\"It's a project that is exceptionally\nmultidisciplinary,\" says Lawrence, a past\nASI fellow. \"We've tapped into the knowledge base of CICSR people and others to\nmake this happen.\"\nThe team relies on statistical methods\nand functional approximation theory to\nbuild a system that will successfully and\nquickly capture and classify a large number\nof measurements. The classification scheme\nis being refined and simplified by\nSaboksayr. A neural network is being\nengineered so the system can train itself\nto learn board characteristics and build a\ndatabase. Board information will be\nsupplied on a CD-ROM as a system\nreference.\nThe system promises to significantly\nimprove the return on graded lumber.\nLandmark Truss & Lumber of Abbotsford,\nBC will be a testbed site for the new\ntechnology.\n\"It's a classic case of adding value to our\nimportant timber resource,\" says Frank Lam.\nThe $1.4-million project is being funded\nby CAE Newnes and Precarn Associates,\nand will be completed by March 2000.\nPeter Lawrence can be reached at\npeterl@ece.ubc.ca and (604) 822-5934.\nFall 99 Evans ends term as head of Mechanical Engineering\nWhen Bob Evans, of Mechanical Engineering, was asked what he looked forward to as\nhe prepared to step down as head of the\ndepartment, he answered with one word:\n\"Time!\"\n\"I'm looking forward to having time for\nreading, writing and generally catching up\nwith my research work,\" he added. \"And\nhaving more time to spend with my family.\"\nEvans has been head of the department\nfor five years and before that was associate\ndean of Engineering Student Services for\nthree.\n\"Over the last five years Bob Evans has\nprovided exemplary service to the Faculty of\nApplied Science,\" says Michael Isaacson,\ndean of Applied Science. \"He has taken the\ndepartment through some very positive\nchanges.\"\nOne of those changes was bringing new\nfaculty members into the department.\n\"We have made some outstanding\nappointments of young faculty members\nwho will lead our department well into the\nnext century,\" says Evans.\n\"I believe that faculty renewal is one of\nthe most important tasks that a department\nhead can take on.\"\nHe also oversaw equipment and course\nBob Evans: \"He has taken the department\nthrough some very positive changes.\"\nimprovements in the undergraduate\nprogram. Over the past five years, the\ndepartment has upgraded its undergraduate\nlaboratories, and introduced a one-week\nundergraduate machine-shop practice\ncourse that has been well received by\nstudents.\nBudgetary issues are a constant source of\ndifficulty for university administrators, and\nEvans has had to face his share. \"We have\ncontinued to see reductions in our operating budget each year, with the resulting loss\nof both faculty and staff positions.\"\nEvans credits CICSR with helping to\nlessen some of that financial burden, and\ncontributing to the continuing success of\nthe Mechanical Engineering department\ndespite its budgetary setbacks.\n\"CICSR has had a very positive impact\non our department,\" he says. \"Through the\nfaculty appointments and operating funds\nmade available by CICSR we have been\nable to greatly strengthen our research\nactivities in the areas of controls, robotics\nand manufacturing.\"\nAs for the future, Evans sees the department consolidating its position as one of\nthe strongest ME departments in Canada.\n\"We have an extensive and varied\nprogram of research and a very solid\nteaching reputation,\" he says.\"I think we\nwill see more team-work as our faculty\nmembers join together to move to the next\nlevel in their research activities.\"\nThe department itself has moved to a\nnew level, thanks to Evans's leadership.\nDean Isaacson sums it up: \"We are all\ndeeply grateful to Bob for his invaluable\ncontributions.\"\nNational Science Foundation's Year 2000\nconference to be held in Vancouver\nVancouver will be the host city for the National Science Foundation's annual Design and Manufacturing Research Conference.
