Pushing a button, entering the elevator in Ethiopia, choosing the floor you want to go to, waiting a few minutes, and then exiting the Elevator Company should be the most complicated part of using an elevator. Having said that, the user must rely on a large number of affordances and identifiers in order to have faith in the fact that this series of events will proceed without a hitch. For instance, a common affordance that manufacturers provide to notify the user that their input floor has been received by the system is an LED light surrounding the buttons. When you push a button, the light turns on, and when the floor is reached, the light turns off. This affordance is provided by manufacturers to notify the user that their input floor has been received by the system. Although this is a relatively insignificant aspect, its absence may result in a discernible change.
When I take an elevator that has that LED, all I need to do is push the button, and then I can sit back and relax until I get to my destination. If there is no such feedback provided, I first wait for the elevator doors to close, then I wait to see (in anticipation) whether the Elevator Company will go up or not; if it does go up successfully, I then need to be alert to make sure that I get off on the correct floor rather than some other floor the elevator in ethiopia was called to . However, if there is no such feedback provided, I wait for the elevator doors to close first, then I wait to see (in anticipation) whether the elevator will go up or not. In the grand scheme of things, the absence of something as insignificant as a light notifier could result in a negative experience. The purpose of this example is to illustrate the significance of receiving feedback.
The picture on the left depicts an elevator that can be found on campus. The only noticeable difference is the presence of a card swiper, which gives it the appearance of a standard elevator. The swiper serves as an indication that certain floors are restricted from public access while others do not have any restrictions. Nevertheless, which floors have the additional security? The only way to find out is to practise making mistakes and learning from them.
In addition, if the user presses the button while attempting to go to a restricted floor, the LED light that surrounds the button will illuminate for a split second before going out again. What kind of information is the user supposed to gain from this if it’s the first time they’ve ever been in the elevator in ethiopia? Does the fact that the light turned on indicate that the system has understood the input that was provided by the user? Does the fact that it just blinked indicate that there is a problem with the hardware? My first inclination was to try pushing the button one or two more times when I tried to reach a floor that I believed I had access to but that was, in fact, secured. It wasn’t until the elevator doors opened and closed twice on me that it dawned on me that I was trying to access a secured floor.
Despite the fact that I may not have been in the best shape possible, the product is supposed to provide this kind of information to the user in a way that is both clear and immediate Vaccum Elevator in Ethiopia. That is the most important thing to me in a layout. This product does not fulfill those requirements in any way. It’s possible that this is due to the fact that the floor restriction wasn’t implemented until after the Elevator Company was already in place. Memorability is also low because there is no guarantee that the same floors will stay secured (as I’ve come to experience); learnability is high because once it has been learned that a blinking light indicates a secure floor, it sticks; affordances are also clear—you need to swipe your card to get in. Regardless, the efficiency is low due to the lack of indicators and immediate feedback, as it takes time for the user to realize they’ve made a mistake and react to it accordingly (i.e. remains lit until the target floor is reached).
The modification that would require the least amount of effort to implement would be the addition of a warning notice that specifies which floors have security (bottom left image). An additional set of small LED lights could be added next to the floor buttons, along with an icon of a padlock next to them (bottom middle), or the LED lights could surround the buttons (bottom right) in Ethiopia: a light on would indicate that the floor is secured, and a light off would indicate that it is not. This would be a slightly more complex solution for the manufacturer Elevator Company to implement. This would make it possible to have individualized configurations both within a single building, which is not a scenario that is likely to occur frequently, and when moving from one building to another in Ethiopia (i.e. the manufacturer can sell the same model to multiple different buyers).
