Many people go to bars nightly for a few drinks to relax and interact with friends and strangers. When bars get crowded, the situation can sometimes turn from relaxing to stressful. Instead of enjoying your drinks while mingling with friends, you can find yourself annoyed and frustrated at having to wait a long time to obtain your drinks. We hope to combat this problem by creating kiosks placed throughout the bar at tables and other stations. These kiosks then allow the customer to order his/her drinks while avoiding the inconvenience of waiting in line. Whenever the customer wants a newdrink, he simply submits his order from the table that he is sitting at and has the drink delivered to him as soon as it is prepared.Task AnalysisPeople using our system will be the bar’s patrons, which are usually young men and women with no distinguishing skills, habits, preferences, and physical characteristics except for the fact that they enjoy the bar environment. A high percentage of them are likely to have debit/credit cards that they use to pay for their drinks. The bar patrons currently purchase drinks by waiting in poorly formed lines/crowds around the bartendersworking at the bar. A “veteran” bar patron can usually make his way through the line much more quickly than a novice. If a person is new to waiting in line at a bar, he can find himself waiting in front of the bar for a long time while people who have not waited as long get served before him. This can prove to be very frustrating.The user should not need specific instruction to use our interface, instead he couldlearn how to order the drink as he is going through the process of ordering the drink. This means that the interface design should be as simple as possible and maybe mimic existing interfaces so that it is easy to learn in one attempt.The kiosk will be used in a bar environment. That is, it will be noisy, dark, and there will be lots of drinks around. People are likely to have wet hands from the condensation of the drinks. The tables are likely to get dirty. All this means that the touch screen interface should not rely on any sound for I/O, the screen should light itself so it will be visible, and the screen should be able to bear the spilling of drinks and be very durable. A rule of use for the kiosk is that if a customer orders from a certain table, they must remain there until they receive the drinks they ordered. The bar knows where to deliver the ordered drinks by identifying from which kiosk the order was received. The customer will always have access to his order information because he will be seated at the table from which he made his order. Nobody else will be able to access the customer’s order because only the customer will have access to the kiosk at his table.Access to order information is not restricted. If the customer wants to leave his table, he must cancel his order to be sure that it is safe.If the customer ever changes his mind on his order or realizes that he has made a mistake, he can always cancel or modify the order up until it is actually being made. Thisis because the status of his order is always visible on the screen after the order is made, and there are options to view, modify, or cancel the order.Contextual InquiryWe went to Henry’s Bar and interviewed, observed, and followed three bar patrons throughout a Tuesday night. Henry’s is very crowded on Tuesday nights and waiting in line for drinks becomes a major consideration. We followed one female and two male Berkeley students. We followed these people around, allowing them to lead all interactions and make all bar decisions. As they would move around or decide to buy drinks we would ask them questions such as why they are buying drinks now, why they are buying the quantity of drinks they are buying, and why they position themselves at certain locations in the barWe chose these people based on the following criteria. We wanted to follow regular bar goers. This is so that we could see how somebody who has adjusted to the current practices of the bar scene conducts his night. Specifically, we wanted to see what course of action people have decided is the best way to cope with the long lines. We wanted to see if this altered behavior is something that is detrimental to the bar experience as a whole or if it is trivial. To what extent is behavior altered due to the lines? We interviewed one more male than female because the males tend to buy more drinks than the females both because they drink more and that they buy drinks for the females.We came to some interesting conclusions. The first characteristic of the environment that we noticed was that although the bar was very crowded, the crowd was not spread out evenly throughout the bar. Half of the bar was relatively empty, while sideof the bar closest to the drinks was overly crowded. The location of drinks dictated where everybody was positioned. Another habit which we concluded was directly due to the problem of waiting in line is that people ordered more drinks than they wanted to consume at a certain time so that they have more time to interact between waiting in line for drinks. However although buying two drinks at a time for a person saved them waiting time, it also ended up limiting them. One person who we were observing was reluctant to change positions in the bar because he did not want to be seen carrying two drinks in his hand. As a result he positioned himself beside a table so that he could place one drink on the table and have the other drink in his hand. Another effect of the crowded section around the bar is that people who bought their drinks often times had a lot of trouble carrying all of them away from the crowded section.All of these observations led us to come to the conclusion that the bar (the location of ordering drinks) and line overly dictate the behavior of the patrons, and that the use of kiosks will likely improve
