“HCI Research as Problem-Solving”(CHI’16) で学ぶ What is HCI Research ?

『HCI研究おもちゃ論争』が昨年勃発していた.
https://togetter.com/li/1334884

また,昨年は一時期HCI系研究をやろうとしていた(予算が取れなくてやらなかったが)こともあり,その際「HCIってそもそもなんだっけ?」ということを勉強していた.
その学びを整理する上で,研究室内でのプチ勉強会を開催した.
本スライドはその時に使用したものである.

  4. 7 Abstract Let’s Start This essay contributes a meta-scientific account

    of human– computer interaction (HCI) research as problem-solving. We build on the philosophy of Larry Laudan, who develops problem and solution as the foundational concepts of science. We argue that most HCI research is about three main types of problem: empirical, conceptual, and constructive. We elaborate upon Laudan’s concept of problem-solving capacity as a universal criterion for determining the progress of solutions (outcomes): Instead of asking whether research is ‘valid’ or follows the ‘right’ approach, it urges us to ask how its solutions advance our capacity to solve important problems in human use of computers. ……
