Project 1 Final

Project 1 Final

After making our (nearly) full-scale cardboard prototype of Old Bean and presenting his form and interface, we received not only the student feedback as mentioned before, but also a few suggestions from Nassim.

Her suggestions, and additional suggestions from classmates, included the following:


-Inviting Welcoming Text
-Touch Screen to begin
-News Topic Buttons
-Change & Receipt spaces
-Update prices with size changes
-Take out green/red buttons and use more gestural feedback from the robot
-Research some robots to learn affordances of robots
-Get rid of embarrassing RSS feed font…


These adjustments were taken into consideration for Old Bean’s final form. As much as we wanted to go back into robot vending machine research to include useful features into our re-design, we acknowledged the fact that there were severe time constraints. So, we went back to make the more necessary changes to old bean. First, we decided to drop voice-activated ordering altogether. Although it would be a fun way for users to interact, we decided its first priority as a vending machine should be speed and efficiency. Enabling the users to carry on conversations with Old Bean, and maybe somehow give hackers incentive to ‘break’ him, was ultimately decided against. Because of the confines of the space we were designing for (remember, the Student Center post office area), we were cautious about adding too many novelty physical features to Old Bean. Gestures like waving, pulling levers, or moving too much might obstruct the flow of the space he would be placed within.

The primary features we kept for Old Bean were:

1. The novelty Old Bean personality and interaction.
2. RSS news feeds and topics the Old Bean can update with using Wifi.
3. Interactive and in-depth touch screen to enable drink customization and user satisfaction.


We felt that these were the most important improvements for the old coffee vending machine as it enhances the user’s experience, service compared to a coffee shop (or the cafeteria), and drink quality and customization level. The ‘button grid’ system used by the old machine is just too outdated and does not compete well against the level of drinks that companies like Starbucks can produce only a short walk from the machine. We believe that Old Bean would not only give consumers incentive to choose the vending machine first, but also brighten up their day with a clever, British robot butler.

Here is a link to the interaction case video on youtube that demonstrates how a user would order coffee from the Old Bean. Note that these use cases to not involve the Old Bean personality or news feed options, but just the ordering process.
