Introduction

Cities contain loads of birds who cannot find enough food to stay alive. Therefore, many people help these birds by supplying them with food like seeds or peanut butter. This helps most of these birds to get through the cold winter months. However, if you have ever looked outside at one of these food spots, you might have noticed that strong or large birds often hog these for themselves. This scares away small birds, who need food more than large birds. For example, in the Netherlands, a big subset of these strong birds are Magpies, who are quite aggressive. They will guard these feeding spots often and prevent tiny Sparrows from getting food.

To help these smaller birds, we want to create a feed-dispenser-type device. It will be able to detect what birds are around it and will close off access to the food if large birds are trying to eat. To help you as a user in finding a good spot and making sure that the container will not get empty. It will send notifications about which bird is eating food, it will also send the current food level.

State of the art research

Before conducting interviews to gain a better understanding of the problem and how the product should be designed state of the art research was conducted.

USE

Users

An automatic bird feeder can be made into a product suitable for multiple purposes and can be interesting for different users. Most birdfeeders are in gardens of people who simply like to watch birds from the comfort of their homes. However, they do not know when birds are feeding and thus when they can watch them. The automatic birdfeeder is ideal for this type of situation because it can send a message to the user's phone alerting them which type of bird is in their garden. For example, an elderly man who loves to bird watch has 2 feeders in his garden at different places around his house. His vision is a bit impaired, so he cannot keep a close watch on the feeders since this costs too much energy. With the automatic birdfeeder, he does not have to keep a close watch since he now knows when and which bird is feeding, giving him a very pleasant user experience.

The automatic birdfeeder can also be used for wildlife conservation in areas where certain species have a difficult time surviving. Many habitats have exotics, species not native to an area, that were taken as pets from different countries and escaped. These exotics pose a big danger to the biodiversity of ecosystems since they do not have natural predators living there. As a result, the numbers of their population increase rapidly, leaving not enough food for native species. With the automatic bird feeder, wildlife reservists can help the native species by giving them food without the exotics benefiting from their advantage. The automatic birdfeeder can also help in helping to understand the severity of the problem by keeping count of the birds that tried to feed. This is also interesting for researchers and ornithologists to preserve ecosystems better since birds play a vital role in almost all ecosystems globally.

For the scope of this course, we decided to focus on the group of people who just like to have a feeder in their garden. To understand their needs better, we have conducted multiple semi-structured interviews with different users. The first questions were open questions regarding peoples bird watching behaviour. The latter questions were more guided by already identified possible features. These features were a way to scare off larger birds, a notification feature, bird identification and overfeeding prevention. The participants gave their thoughts on the proposed features and ranked them from most useful to least useful. The research questions and short summaries of the interviews can be found in Appendix D and Appendix E. From the answers, an affinity diagram was made with five different identified themes.

Requirements

MoSCoW

From the affinity attributes requirements for the bird feeder were made and ranked according to the MoSCoW Theory.
