I am gathering information on the history of devices and tools used in user and product research. For example:
-What data collection devices have been used to capture how people use products (both currently and historically) - for example journals, photographs.
-What tools have been used to measure people, products and environments to ensure ergonomic fit?
-Also look for more general/historical research tools such as t-scopes, etc.
Please post responses to this thread via the comment feature or direct reply to me (firstname.lastname@example.org). Any existing sources of information on this topic would also be appreciated.
