%% Facial/Emotional Recognition with Chatbot
Problem statement
For the past few decades, the population of old people has been rapidly increasing, due to the advancement of healthcare education. This rapid increase means that a lot more caretakers are necessary to help get those people through the day. Not only physically, but also mentally. Depression and loneliness are right around the corner for a lot of old people if there is not enough interaction with caretakers or family members. One study showed that there is a significant relationship between depression and loneliness of the elderly. Meaning that if there is not enough social interaction, they will have a high chance of developing a severe depression further growing the feeling of loneliness.[1] It is therefore vital that there are enough caretakers to prevent this. Unfortunately, the shortage of caretakers is growing. To combat this the usage of care take robots is being developed quite extensively. These robots can not yet replace the full physical help a real person can give but can give some mental help by giving the elderly someone to talk to. This social interaction can include having a simple conversation with the person or routing a call to family members. In order to have a more complicated conversation, the robot requires to understand more about the state of the person. Finding the state of a person is very important as humans are emotional creatures. If a robot could get a clue how someone is feeling, this could greatly improve the interaction. While increasing the intelligence of the robot would solve this issue, this proves to be very difficult. Therefore, only small steps in increasing the robots world view can be made.
Objective
The proposal for this project is to use emotion detection in real-time to get a feeling about how the person is feeling so that it can use this information to further help the person. This reading of emotions from the face will not be perfect, but there are already some good results using neural networks.[2] However, the implementation of this emotion detection for specific use on the elderly with a chatbot has not been explored very deeply.
Previous Work
The facial recognition with emotion detection software has already been done before. One method that could be employed for facial recognition is done by the following block diagram:
This setup was proposed for a robot to interact with a person based on the persons' emotion. However, the verbal feedback was not implemented.
USE Aspects
Users
Lonely elderly people are the main user of the robot. How these elderly people are found is via a government-funded institute where people can make applications in order to get such a robot. These applications can be filled in by everyone(elderly themselves, friends, physiatrists, family, caretakers) with the consent of the elderly person as well. In cases where the health of the elderly is in danger due to illnesses(Final stages dementia etc) the consent of the elderly is not necessary if the application is filled by doctors or physiatrists. If applicable a caretaker/employee of the institute will go visit the elderly person to check whether the care robot is really necessary or different solutions can be found. If found applicable the elderly will be assigned a robot. They will interact with the robot on a daily basis by talking to it and the robot will make an emotional profile of the person which it uses to help the person through the day. When the robot detects certain negative emotions(sadness, anger eg.) it can ask if it can help with various actions like calling family, friends, real caretakers, or having a simple conversation with the person.
Society
Society consists of three main stakeholders. The government, the medical assistance and visitors.
The government is the primary funding for an institute that regulates the distribution of the emotion detecting robots. With this set-up, the regulation of the distribution is easier as the privacy violation of the real-time emotion detection is quite extensive. Furthermore, the government is accountable for making laws to regulate what the robots could do and how and what data can be sent to family members or various third-parties.
Secondly, the robots may deliver feedback to hospitals or therapists in case of severe depression or other negative symptoms that can not simply solved by a simple conversation. The elderly person who still has autonomy as the primary value must always give consent for sharing data or calling certain people. For people with severe illnesses, this can be overruled by doctors or physiatrics to force the person to get help in the case of emergencies.
Finally, any visiting individual may indirectly be exposed to the robot. To ensure their emotions are not unwillingly measured or privacy compromised, laws and regulations must be set up.
Enterprise
Robots must be developed, created and dispatched to the elderly. The relevant enterprise stakeholders, in this case, are the developing companies, the government, the hospitals and therapists to ensure logistic and administrative validity.

Approach
This project has multiple problems that need to be solved in order to create a system / robot that is able to combat the emotional problems that the elderly are facing. In order to categorize the problems are split into three main parts:
Technical
The main technical problem faced for our robot is to be able to reliable read the emotional state of another person and using that data being able to process this data. After processing the robot should be able to act accordingly to a set of different actions.
Social / Emotional
The robot should be able to act accordingly, therefore research needs to be done to know what types of actions the robot can perform in order to get positive results. One thing the robot could be able to do is have a simple conversation with the person or start the recording of an audio book in order to keep the person active during the day.
Physical
What type of physical presence of the robot is optimal. Is a more conventional robot needed that has a somewhat humanoid look. Or does a system that interacts using speakers and different screens divided over the room get better results. Maybe a combination of both.
The main focus of this project will be the technical problem stated however for a more complete use-case the other subject should be researched as well.

Implementation of facial data in chatbot
Once the facial recognition software has gathered information about the emotional state of the person this information has to be implemented somehow. In this section, there will be discussed how the state of the person will help the robot to personalize how it reacts to the person.
Data to use The recognition software will detect both whether there is a face in view, together with what emotion is expressed and with what intensity. This data can then be used to determine how positive or negative the person is feeling. These negative emotions are very important to detect, as prolonged negative feelings may lead to depression and anxiety. Recognizing these emotions timely can prevent this, negating help needed from medical practitioners.[3]
One very important thing is what kind of emotional interpreter is being used, as there are many different models for describing complex emotions. The most basic interpretation uses six basic emotions that were found to be universal between cultures. This model was developed during the 1970s, where psychologist Paul Eckman identified these six basic emotions to be happiness, sadness, disgust, fear, surprise, and anger.[4] [3]Maja Pantic and Marian Stewart Bartlett (2007).
