There's a probability for picking up infections for every object you touch, which is proportional to the number of hands that touched it prior to your operation

There's a probability for picking up infections for every object you touch, which is proportional to the number of hands that touched it prior to your operation. If this is a significant problem compared to human cashiers, there's an easy fix that is the same with bathrooms and tables: require that janitors on duty sanitize them every X hours.
Also, I've used automatic ordering touch screens before and didn't have any difficulty. I feel that the employee's response "She sighed, looked me in the eye, and confessed “Everybody does.”" is exaggerated. What she meant was probably "It's super easy but some customers still can't get it, so I will sympathize with you because saying 'no, it's easy' would be rude."

- vortico 8y agoHow much are these? (USD ea for 100,000 volume, say)
- AstralStorm 8y agoNo idea, I'd need a Chinese contract, but cheap enough that Apple considered getting these in iPads. Instead of ITO (indium tin oxide) coating you use AgNW (silver nanowire) coating. Unlike ITO this can be painted onto more substrates instead of vapor depletion. Useful for more flexible touchscreens.

- chaoticmass 8y agoI've used the Kiosks at McD's and it really was baffling trying to figure out how to order a combo meal. I figured I could just go to [Combo Meals] -> [#X Quarter Pounder] Instead you have to pick the burger, then way down on the bottom (where you're not looking because the screens are vertical and huge) there is a button to make it a combo. I never found the combo button on my own and had to ask. You'd think since most people order combos they would make it more intuitive to order those. Finally, there are some combo meals (two cheese burger meal) that you can't get as a combo from the kiosk. You'd have to order single cheese burger combo, customize it, add to order, then select a 2nd cheese burger and customize it-- except you can't because the single patty cheese burger can't be made into a combo meal (the combo button doesn't appear). So then you have to just pick the burger, add fries, drink, etc and presumably pay more. To a human I can just say "number X with ketchup and mayo only" and they have it rung up in seconds where it takes much longer on the kiosk.
- vortico 8y agoI haven't tried ordering combos (don't really like sodas), so I haven't had this experience. I feel it would be fun to be on the team to test and design revisions to the touch screen menu.
- chaoticmass 8y agoYeah, for such a huge company, who surely spend lots of money researching how to understand and optimize customer interactions, they really dropped the ball on their UX design on the kiosks.
