Ian Porteus Howard (July 20, 1927 – June 1, 2013) was a Canadianpsychologist and researcher invisual perception atYork University inToronto.^[1]

Ian Howard was born inLancashire, England, close to theYorkshire border. He studied for a BSc atManchester University, graduating in 1952. Howard held academic positions in Departments of Psychology atDurham University (1953-1964) (from which he obtained his PhD in 1965), atNew York University (1965), and atYork University in Toronto (1966-2013). At York University, he contributed to the development of the Department of Psychology and, in 1992^[1] founded theCentre for Vision Research (CVR).

While at York, Howard became full professor. Upon retirement in 1993, he became Distinguished Research Professor Emeritus, a position he held until his death.

Howard was renowned for his research into human visual perception.^[2]

In June 2013, Howard had anh-index of 35.^[3] During his time at York, Howard hiredMartin J. Steinbach as his first postdoctoral fellow (1968) and supervised four PhD students.^[4]

In 1956, Howard married Antonie (Toni) Eber. They had three children: Ruth, Neil and Martin, and 7 grandchildren: Colin, Graeme, Alice, Shifra, Helah, Eli, and Katie/Mika.^{[citation needed]}

Ian died of cancer on 1 June 2013.^[5]

Howard's research areas included humanspatial orientation (how we tell whether we are upright or lying down),stereopsis (how we sense the distance of objects from our eyes from the differences in the images in the eyes),eye movements, andperceptual ambiguity. Howard was reluctant to use computer-simulated stimuli for his studies; Howard's approach was to study visual perception in realistic settings with real objects, unlike many others in the field, who studied it using pictures of objects. Realistic settings Howard constructed included a full-size rotating room and a 3-m-diameter sphere. He also researched human orientation inmicrogravity using the "vomit comet"^[6] and theSpace Shuttle.^{[citation needed]}

Howard was renowned for his kindness and sense of fun and curiosity. For one example, visitors to Howard's laboratory would inevitably be offered a ride in the rotating room, which contained a sturdy seat into which a willing visitor would be strapped with aircraft-type seatbelts. The seat was on one wall of the room, giving the occupant a view of the rest of the room, consisting of conventional furniture including a coffee table with (at one stage) a Time magazine with Mikhail Gorbachev's photograph on the cover resting on it, a light fitting hanging from the ceiling, a window on the left wall giving a view of a photograph of a natural scene, and the closed entrance door on the right wall. Although the seat could be rotated in the x-y plane (i.e., potentially rolling the occupant around his or her line of sight), the room itself was rotated, giving the same visual consequences as if the occupant had been rolled. Many occupants perceived themselves to be rolling, a phenomenon known asvection.^[7][8]

For another example, while at York he and his wife, Toni, held annual parties at their house for all members of CVR and for anyone else who wanted to attend. The house and yard were filled with puzzles and toys for all guests to enjoy. Outside toys included azip-line that took riders for an exhilarating ride down through the yard and into trees, and something like an extremely sturdyrotary clothes line with a parachute harness on one arm and a rope on the other. A rider got into the harness and someone else grabbed the rope and ran around the central axis of the device, tugging the rider faster and faster until he or she was nearly horizontal to the ground because ofcentrifugal force. One of many experiences of the rider was that he or she was stationary and the visual world was rotating.
