Problem statement

More elderly have to live at home because there is not enough personal staff in elderly homes and the number of elderly grows every year. Moreover, there is a trend of elderly who want to live independently. However not all elderly can live independently, they depend on home care, but home care cannot keep an eye on the elderly all the time.

Objectives

Our objectives are to help the elderly to live more independently at home and to give the home care a better overview of what is going on in the house of the elderly. Moreover, to give the family more comfort about how the elderly are going.

Users

First, the primary users, which are:

• the elderly
• the home care

Secondly, the secondary users, which are:

• the family
• the friends
• the government

thirdly, the tertiary users, which are:

• the technicians

Requirements

Requirements of primary users:

• The elderly need a system that helps them to be more independent.
• The elderly need to be reminded to take their medicine.
• The elderly need to be reminded to eat when they skipped a meal.
• The elderly need to be reminded to water the plants and keep busy.
• The home care needs to get a lower work pressure and a better overview of the state of the house of elderly.

Requirements of the secondary users:

• The secondary users need their elderly to be independent.

Requirements of the tertiary users:

• The tertiary users need a system that is easy to install and easy to maintain.
• The tertiary users need a system that gives a notification in case of an error or when it needs maintenance.

Approach, milestones and deliverables

Our approach will be based on a divide and conquer strategy. We will divide the big problem into subproblems, which we will solve independently and then put them together to get the big solution. The problem is to make some kind of smart house for a home living (forgetful) elderly, which need home care. Elderly live (better?) when they take care of things and keep busy. So having plans and hence responsibility to take care of the plans. Furthermore, most elderly have to take medication. However, they can forget to take those medications in time. Moreover, some elderly sometimes forget whether they have already eaten a meal or not. Furthermore, the temperature and oxygen levels are important to keep an eye on, whether the elderly take good care of themselves. So some milestones are:

• A system that recognizes that plans need watering and a system to notify the user that the plant needs care.
• A system that registers whether the user has eaten a meal and notify the user if the skipped a meal.
• A system that measures the temperature in the house and the oxygen levels.
• A system that helps the user to be reminded that medications need to be taken.
• A system that will keep the home care up to date about what is happening in the house.

For these subsystems, we need to build prototypes and test these. But for this, we first need to investigate the state of the art. The deliverables of this project are the systems who should work together as a whole and the prototypes of these systems and hence a prototype of the whole.

Literature study

The literature study can be divided into a few subjects. First of all a broad study of smart homes.

• (fill in source)
• Source connecting people with dementia to smart homes
• Smart home for elder care using wireless sensors

Secondly the state of the art of medication reminders.

• (fill in source)
• Smart home medication reminder system

Thirdly the state of the art of robots who take care of plants.

• (fill in source)

Fourthly the state of the art of robots who look at the eating of their users.

• (fill in source)

Lastly, the state of the art of thermostats and of measurements of oxygen.

• Neofox oxygen sensors: precise oxygen sensors for both liquids and gasses.
