Imagine asking AI to plan your trip itinerary, book and pay for all your flights, and arrange your airport transport — all within a single click. Fortunately, an international research team is making this vision a reality.  

The team, composed of researchers from the University of Waterloo, University of Hong Kong, Salesforce Research and Carnegie Mellon University developed Computer Agent Arena — an evaluation platform that can enhance and create computer agents. 

A computer agent is a type of software that can perform tasks on behalf of a person or organization, without needing constant human intervention. It can interpret the state of the computer and act autonomously to help users solve problems. Examples of computer agents include voice assistants like Siri and Alexa, who can help users send messages and schedule meetings.  

AI-based computer agents struggle with performing complex computer tasks because it requires controlling multiple computer applications and various steps. For example, filing an expense report may be difficult because it requires updating a spreadsheet by searching multiple emails and folders filled with bank statements and receipts.  

Computer Agent Arena is the first interactive computer use evaluation platform that focuses on performing diverse tasks across multiple applications. This work is an extension of the researchers’ work on OSWorld, the world’s first scalable and real computer environment for multimodal agents. 

 “Computer Agent Arena provides a platform for the research community to develop effective and efficient agents that generalize to real-world computer usage,” says co-developer Dr. Victor Zhong, assistant professor at the Cheriton School of Computer Science. Like other Waterloo researchers, he is investigating human-technology interactions, exploring how to mitigate everyday problems by creating novel technologies.  

“Computer Agent Arena is distinct from similar research like Mind2Web and WebArena because it provides unified application programming interfaces for comprehensive observations and actions in an executable environment with multiple applications.”  

Through Computer Agent Arena, users can assess and compare various computer agents based on large language models (LLM) and vision language models. First, users select an operating system such as Windows, and applications like Google Chrome and Excel. Users can then prompt the computer agent with a task, which will be performed simultaneously by two AI models in real-time. After completion, users can rate each model’s performance and provide feedback.  

Ultimately, the team seeks to provide a diverse and dynamic platform for building and evaluating agents that can perform real-world computer tasks as safely, effectively and efficiently as humans do. 

“Our current findings show that foundation models such as GPT4 and Claude are far from being able to act safely and effectively as assistant computer agents,” Zhong says. “Computer Agent Arena provides a timely testbed to develop the next generation of AI agents.”

Nutrition Month: food and sociocultural wellbeing

Nutrition Month banner featuring the slogan "nourish to flourish."

A message from Campus Wellness and Food Services.

This year’s Nutrition Month theme, Nourish to Flourish, focuses on the powerful role nutrition plays in helping individuals and communities thrive. Over the month of March, we will be highlighting the role nutrition plays in physical, mental, sociocultural and emotional wellbeing. 

The focus this week is on Sociocultural Wellbeing. 

Food connects families, communities, and cultures. Dietary patterns are a reflection of who we are. From family traditions to cultural and religious practices, food is more than just nutrients - it connects us to our families and communities and helps shape our identities. Social activities and celebrations often involve food. They can add value to our personal relationships as well as nurture positive food experiences.  Important factors that often influence our day-to-day food choices include busy schedules, food costs, cooking skills, and family dynamics. 

Tips to consider:

  • Making time to enjoy a meal with friends or family can nurture social relationships and a positive relationship with food. By sharing food skills, we can explore new foods, cultures, and traditions while enjoying quality time with others
  • Reflecting on the role specific foods or food traditions have in our lives can enhance our overall appreciation and understanding of food values
  • Choosing foods that align to your personal needs, preferences, and values demonstrates self-care and can help create enjoyable eating experiences​

 Remembering Professor Ian McGee

Professor Ian McGee.

This article was originally published on the Faculty of Mathematics website.

Dr. Ian James McGee, a professor emeritus of Applied Mathematics at the University of Waterloo, died on February 20, 2025. He was 87.

McGee was born on November 9, 1937, in Toronto, ON, one of four siblings. A “renegade” as a child, he frequently got in trouble in elementary school, with the principal once telling his parents that “at this rate, Ian won’t make it past grade eight.”

McGee's attitude towards school changed thanks to his sixth grade math teacher, who introduced him to logic puzzles and ignited his lifelong love of math and science. With the mentorship of other teachers throughout the years, he began to thrive at school, ultimately graduating as high school valedictorian.

McGee also met his beloved wife, Dawna, as a child: they grew up a block away from each other and attended the same elementary school, beginning to date in Grade Thirteen.

McGee earned his Bachelor of Applied Science, Engineering Physics from the University of Toronto in 1960. He then came to the University of Waterloo for the first time, earning his Master’s of Science in 1961. A PhD in Theoretical Physics at Yale University followed in 1965, then post-doctoral studies at the University of Wisconsin from 1966 to 1967.

In 1967, McGee was hired by the University of Waterloo as an associate professor in Applied Mathematics. He remained with the Applied Mathematics department throughout the rest of his career, save for an eighteen-month term as a visiting professor at the University of Newcastle & Australia University from 1974 to 1975.

McGee served as associate dean of the Faculty of Mathematics from 1976 to 1980. Reflecting the pivotal role his own teachers played in his life, he was passionate about education. In 1991, he received the Centre for Teaching Excellence’s Distinguished Teacher Award. As one of his former students noted in the citation, “Not only has he been able to teach the subject matter itself in a useful and interesting manner, but his attitude towards mathematics and his enjoyment of its applicability has nurtured and strengthened a similar attitude in me. This attitude and his skill in presenting a subject clearly and truly without a dull moment have convinced me that mathematics is indeed a wonderful science.”

While McGee was never official part of the Centre for Education in Mathematics and Computing (CEMC), he was a longstanding “friend” of the Centre, participating regularly in math contest creation and marking. As retired CEMC member Ed Anderson recalls, “Any activity that involved engaging with young people was not something that Ian ever considered as work.”

McGee and his wife Dawna had three daughters and six grandchildren. An avid amateur athlete, he won many awards as an A-level squash player at Northfield Racquet Club, and enjoyed watching sports live and on TV throughout his life. He also loved to travel, visiting every continent including Antarctica. He was accompanied on many of these trips by his family, and particularly enjoyed cruises with his family, and adventures with his son-in-law Robin, who is a naturalist and trip leader.  A self-taught classical guitarist, he particularly enjoyed learning and singing Australian folk songs during his term as a visiting professor.

After retirement, McGee stayed active, enjoying puzzles and games, numerous crafts, and outdoor activities. He spent time volunteering in hospice care, clowning with his sister Janet, and serving as an elder at St. Andrews Presbyterian Church. In 2008, in recognition of his work in hospice care, he received the Ontario Medal for Good Citizenship. The citation notes his frequent visits with “palliative care patients and those with Alzheimer’s Disease, offering them compassionate and practical support.”

McGee is survived by his sisters Heather and Janet, his wife Dawna, and his children and grandchildren, as well as their partners. “He was loved by many,” his family notes in his obituary, “and his stories of his life (and his jokes) will continue on.”

Visitation will be held at the Erb & Good Family Funeral Home on Saturday, April 5, from 10:00 a.m. to 11:00 a.m. The funeral service will take place in the chapel of the funeral home at 11:00 a.m. followed by a reception in the Fireside Reception Room. A livestream and recording of the service will be made available on Ian’s tribute page.

In lieu of flowers, condolences for the family and donations to Hospice Waterloo or the Alzheimer Society may be arranged through the Erb & Good Family Funeral Home.
