ESr|s are used where liquids, which can irritate or even harm the eyes, are handled in a way that eye contact is a potential risk
purpose: rinse the eyes thoroughly if they got in contact with these liquids
non-portable safety devices requires high visibility and all-time good accessibility
cannot be taken to where the danger situation currently is (there are exceptions, such as eye-wash bottles)
affected workers need to be able to get to it, even though their vision is already constricted by said liquids
OHS-issue which has to be resolved is the blocked access to the ESr by a large rubbish bag -> user is supposed to "clean up" by moving the bag to a nearby dustbin
Trivia
Very early and very industry-typical object (26th August 2018, 8c66bb40)
We felt to give the user context to motivate for the ESr
added shelf with chemicals jugs next to ESr (has its own OHS issue: Do not put drinking bottles next to other liquids)
to increase visibility we added differently coloured liquids (21st September 2018, 789245cf)
added a routing/drilling machine, which requires a liquid fluxing agent. This agents supply could be stored in the chemicals jugs on the shelf (16th September 2018, d4711e1a)
"untold" background story -> appears on reflection
peer-motivation for ESr
We moved the rubbish bag (and the dustbin?) closer to the ESr to make it more visible by making it more severe
rubbish bag: there is no way to access the ESr any more without removing the rubbish bag (16th September 2018, d4711e1a)
dustbin: easier to find when bag was grabbed
small field of view, dragging needs to track fingers constantly (28th November 2018, f7a731ce)
I know we discussed that but could not find visible evidence in Git Commits
In the early project stages, the ESr was mounted on the real/physical wall (still more AR than AV). After introducing background images, the ESr levitated in front of the space depicted by the background images (21st September 2018, 789245cf) -> designed a column to which the ESr can be (logically) mounted (28th November 2018, f7a731ce)
recognised that dragging is problematic for the user to drag over greater distances, while we focussed less on just having content and more on interaction design (designer place?)
the column design caused changing tools by demand (to make it feasible) not by having more freedoms due to having developed approaches is more basic tools (Unity 3D) (cf. CAa Overview#Reflections)
