CS295J/Triage for class 10

Steven

1. A model of human cognitive and perceptual abilities when using computers

• Extremely relevant, huge impact – though it would require well trained cognitive scientists to properly interpret a huge number of studies as to their relevance to HCI

2. Something about design rules collected and merged

• Doesn’t incorporate cognitive principles, discard

3. A predictive, fully-integrated model of user workflow which encompasses low-level tasks, working spheres, communication chains, interruptions and multi-tasking.

• Doesn’t contribute terribly in terms of cognitive and perceptual modeling, as it works almost exclusively with behavior, but could inform and be informed by other aspects. Would be fairly expensive though, as procuring and analyzing data would be a long process.

4. A low-overhead mechanism for capturing event-based interactions between a user and a computer, including web-cam based eye tracking.

• Very relevant in terms of estimating perceptual patterns and applying cognitive research, could have a very large impact. Cost depends upon equipment, though recruiting fresh users could also be expensive.

5. A classification of standard design guidelines into overarching principles and measurement of the relation of each design principle with quantifiable cognitive principles.

• Very relevant and low cost, though the impact might not be huge.

6. A systematic method to determine task distribution based on psychological principles.

• Could be very impactful and is certainly very relevant, but the cost could be high as this would require multiple experiments and likely advanced imaging tools.

7. A method for collecting data on user performance in cognitive, perceptual, and motor-control tasks that requires less monetary cost, allows for a greater number of samples, and measures user improvements over time.

• Very similar to the event-based interactions contribution above, has similar potential for impact but once again – development costs could be large.
