The Raspberry Pi is a Linux computer that has a multitude of connectors and in particular, it provides GPIO pins. The connector (HAT) provides an easy way to add your own sensors and actuators and there are many boars that can be connected.

Home Office Buddy:
 +
<br/> A speaker communicating in a pleasant way with the target person in order to minimize a possible social isolation and encourage the keeping of important routines & daily structures in order to maintain a certain productivity during a working day.
 +
<br/> Example: suggest unplanned short breaks if the target person is showing a lack of concentration measured by a certain level of body movement.

Problem: Tension due to prolonged sitting and incorrect sitting positions (e.g. crooked shoulders)
 +
<br/> Sensors: Kinect for analysis of posture, sensors that measure the tension in the neck
 +
<br/> The longer one maintains a bad sitting position, the older/bent an avatar becomes on the screen. Through movement the avatar becomes younger/upright again.

* Connect the Pi to your local network and access it from another device via SSH.

 +
Problem: ① Uncomfortable working environment in aspects of lighting and air quality; ② Avoidable disturbance by colleges, etc.; ③ Remaining stationary for too long
  
−
=== Troubleshooting ===
+
Solution: ① Automatic adjustable light, automatic jalousie roller, automatic humidifier, LED as indicator next to windows; ② Display as door sign; ③ Speaker with a switch as indicator

* If updating the Pi fails during its setup wizard (first start of the Pi), you might have to extend your file partition. The wizard interrupts with a "not enough space" error. You can find this option via "sudo raspi-config", select advanced options and expand the filesystem. After a reboot, you should have access to the whole SD card (you can check disk space with "df -h"). Make sure to finish the update with "sudo apt-get update && sudo apt-get upgrade".

Sensor: Temperature and humidity sensor Bme280, light sensor Tsl2561, CO2 sensor, motion sensor

=== HW ===
 +
Problem: Pain in the hand and wrist due to consistent movement or incorrect hand/arm position
 +
<br/> Sensors: e.g. Leap Motion for motion and posture detection, keyboard/mouse to track activity (?)
 +
<br/> Vibration of the mouse/keyboard if the same position was kept for too long or no pause was made. A visualization of an inflammation (red pulsating circles) is displayed, which gets worse/better depending on user behavior.  This warns the user when his hand position is worsening. The user may choose to be prevented from continuing to work or not.
