Observation Assignment
Click on the image
I worked with Gordie and Emily Ryan. We decided to go to a crowded bar and use the opportunity of the super bowl to do our observation assignment.
My first super bowl! Great ! It was at 6:30 pm and the name of the bar is Down The Hatch. I believe there were some 140 people between 21 through 40, mostly students. I actually never understood who was playing or whom I should cheer for.
Anyway, we were expecting to see the bar packed but it was not the case. We had to stand at the corner of the kitchen and lucky enough, this was the best view of the bar. This is why we stayed there. During this important event, people don’t stop communicating between each other. The food arrives at people’s tables. The customers are drinking and using their phones, some of them are talking, others are texting and some cameras here and there. The bartender smiling and working non stop receiving credit cards and serving drinks. Always using technology to solve social interaction but off course the most important for society: joy and have fun.
Here is how we have to think about technology as a social tool that bridges humankind
Women mostly use cell phones, while men were focused on the game. They were texting mainly during the commercials. They used mainly smart phones, blackberries and iPhones. They also had digital cameras which they used to take pictures of each other drinking, having fun, posing, etc.
In the back of the bar, they use a calculator to do the books at the end of the day. The credit card machine is next to the bartender to create easy access. This was the most used machine in the hole assignment, running almost non-stop.
And off course there are the HD TVs in each corner of the bar the tables are arranged around them.
We are creative animals that could think. This is why we are always creating system of communication and social solutions to increase trade.
