Attendees and exhibitors alike judged the 2003 International Robots & Vision Show and Conference (Rosemont, IL; June 2–5) as exceeding expectations, despite about a 15% downturn in attendees and exhibitors from the previous show two years ago. Industry analysts blamed the still weak high-technology economy, the SARS threat, and dormant company investments. The exhibit floor for all three show days was steadily filled with highly interested visitors from 30 countries, especially in the separate Vision Exhibit area.

Most exhibitors were pleased with visitor quality and interest and the upbeat business activities carried out in the booths. Indeed, the number of new vision-related products, technologies, and applications was decidedly higher than at the last show. In addition, some 30 tutorials, conferences, and workshops were presented by industry professionals from around the world.

Sponsored by the Robotics Industries Association (RIA; and the Automated Imaging Association (AIA;, both Ann Arbor, MI, the show presented the latest robots, machine-vision hardware and software products, and related factory-automation devices.

Donald A. Vincent, executive vice president of the RIA, said, "Robots have just scratched the surface of potential applications. Tens of thousands of companies in every industry are just learning about what robots might be able to help them accomplish." Together, robotics and machine vision account for approximately $2.5 billion in annual North American sales.

AIA executive director Jeff Burnstein said, "The machine-vision industry has been hit hard by the cutback in capital spending by manufacturing companies in the United States and throughout the world. The slowdown in the semiconductor (-42%) and electronic industries (-29%), the two largest customers for machine vision, has been a particularly tough blow. But we're optimistic that a recovery is on the horizon, as the AIA forecast for the next five years suggests."

A new AIA market study of the machine-vision industry estimates the North American vision market at $1.5 billion in 2002, a decline of 15% from 2001. However, the study forecasts a market growth of almost 12% a year for the next five years, as the machine-vision industry is expected to recover from the global economic downturn that has hurt capital-equipment expenditures for more than two years.

On the other hand, the study found that the number of vision systems sold into the North American food, container, and pharmaceutical/medical device industries increased. Moreover, only a slight vision system sales downturn occurred in the automotive, plastics, fabricated metals, and wood industries.

The study also contains data on the machine-vision markets in Europe and Japan. It concludes that the total world market in 2002 was $5.3 billion, a drop of about 4% from the 2001 market. The Japanese market was the biggest in 2002 at $1.9 billion. The European market totaled about $1.3 billion.

Several outstanding products were displayed at the show. Cognex Corp. (Natick, MA, USA; unveiled its CDC-200 digital CMOS-based CDC camera series, MVS-8500 series of frame grabbers, and software for its In-Sight vision sensors for reading Composite Symbology and Reduced Space Symbology codes on pharmaceutical packages.

European Machine Vision Association established

The European Machine Vision Association (EMVA) was officially approved as a working organization at the European Machine Vision Business Conference held in Barcelona, Spain, last May. For the first time, nearly 60 European machine-vision company executives, professionals, and managers gathered to discuss market trends and concerns, new products and technologies, and business successes and problems within the European community and to establish a new network of information exchange.

The EMVA is expected to serve as a unified European framework for promoting market and business strategies, techniques, and solutions and sharing common problems and interests. The organization intends to function as an industry lobby to help ensure that leading European products and technologies are more widely promoted, distributed, and applied throughout Europe.

Participating European countries are Belgium, Denmark, Finland, Germany, Greece, Hungary, Ireland, Italy, Slovenia, Spain, Sweden, Switzerland, The Netherlands, and the United Kingdom. However, no French companies attended the conference. Several interested companies from the United States and Canada also attended as observers. Vision Systems Design is the EMVA official media sponsor.

At the conference, 27 companies and three national machine-vision associations voted to accept the association's proposed charter and agreed to join as members of the EMVA. Other attending companies expressed interest in becoming members in the near future. The official language of the EMVA is English.

During the inaugural assembly, the new members of EMVA elected an executive committee of five members who will lead the association for a three-year period. The members are Gabriele Jansen of ISRA VISION SYSTEMS AG, Germany, president; Mats Gökstorp of IVP Integrated Vision Products AB, Sweden, vice president; Toni Ventura-Traveset of DATAPIXEL, Spain, treasurer; Don Braggins of the UK Industrial Vision Association, United Kingdom; and Martin Wäny of Photonfocus AG, Switzerland.

SID 2003 thrives despite attendance decline

Exhibitor-attendee activities appeared busy on the show floor at the 2003 International Conference, Symposium, and Exhibition of the Society for Information Display (SID; San Jose, CA, USA; in Baltimore, MD, last May. Although overall attendance declined moderately and the number of exhibitor booths decreased slightly from last year's show, most exhibitors were generally pleased with the quantity and quality of their contacts.

Industry analysts speculated that the robustness of the SID show reflected the strong growth of the display sector in an otherwise lackluster electronics industry. This reasoning was supported by an attendance of more than 400 at the new SID Business Conference; only about 100 attendees were expected.

The display industry involves several competing viewing technologies as evidenced by the rise and fall of field-emission displays, by persistent work on various approaches to "electronic paper" technology, and by the slow but steady advancement of small organic light-emitting diode (OLED) displays into the mainstream.

While questions remain concerning differential aging of OLEDs, the technology is being adopted in less-critical small-screen applications, such as the EasyShare LS633 digital still camera, which is available in Europe but not yet in North America, from Eastman Kodak Co. (Rochester, NY, USA; Kodak also showed a 15-in. OLED demonstrator.

DuPont Displays (Research Triangle Park, NC, USA; introduced its "Dupont Olight" brand for OLED display devices, along with a five-year plan to provide color devices on flexible plastic substrates to the industrial and other markets.

Toshiba America Electronic Components (Irvine, CA, USA; captured and displayed images of business cards with an LCD panel that can both display 320 × 240-pixel color images and capture 960 × 240-pixel monochrome images.

Planar Systems (Beaverton, OR, USA; showed a 240 × 240-pixel display with an integrated 60 × 60-pixel touch sensor array capable of basic touch-selection functions.

Optiva Inc. (South San Francisco, CA, USA: received the SID/Information Display Display Material of the Year award for its unique material that "self-assembles" into polarizers that can be used in liquid-crystal devices.

The OmniView 360, a stationary optical viewing system with a 360° field of view, was shown by Physical Optics Corp. (Torrance, CA, USA; "We are looking for OEM or licensing partners," said vice president Rick Shie.

"QCIF Full Color Transparent AMOLED Display" by Kwan Hee Lee and others of Samsung Electronics (Suwon City, Gyonggi-do, Korea; described a transparent, 2.2-in., 176 × 220-pixel transparent OLED display that emits light from both sides.

Keithley Instruments (Solon, OH, USA; exhibited at the SID show for the first time "to explore the display business and gain visibility," according to business manager Chuck Cimino. Keithley is working on characterization of OLED current-voltage-light output relationships.

Samsung displayed a 1920 × 1080-pixel, 54-in. LCD and a 1366 × 768-pixel, 63-in. PDP. LG Philips (Seoul, Korea; showed its 52-in.-wide format TFT LCD.

Sharp Microelectronics (Camas, WA, USA; showed its autostereoscopic 3-D LCD in a cell phone. The company also showed its "Advanced TFT-LCD" transflective display technology, which maintains similar color balance and viewing in both dim room light and bright sunlight.
