The virtual interaction space of the skill should ideally be reinforced or encoded in the physical
environment, so that interacting with the robot becomes intuitive from a physical perspective:
● Can the physical setup be used to constrain the number of users to optimal levels ?
● Can the physical design help separate active users from bystanders ?
● Is the camera facing users in the best manner, e.g. enabling their detection as they enter ?
Lighting Considerations
Your robot’s face projection is most vivid in medium and darker indoor lighting conditions and
less vivid in bright direct sunshine. Your robot's camera and perception features require users
interacting with the robot to be reasonably well lit in order to detect, track and identify the users.
Ideal lighting conditions are those where there is less direct light on the robot, but direct light on
the users in the interaction space.
Ambient Noise Considerations
The ambient noise of the environment has a significant effect on the speech recognition
performance of your robot. Noisier environments will cause increases in speech recognition
errors. Environments containing a lot of background human speech “noise” are the most
negative for speech recognition performance. For best performance, we recommend you reduce
ambient noise levels as much as possible
Microphone Placement Considerations
Your robot includes a USB connected external microphone. For optimal performance, the
microphone should be placed on a level surface where it is directly in between the users and the
robot. If placed closer than 10-15 cm to the robot, there is a risk the microphone will pick up fan
noise from the robot. To be able to detect the direction of the user speaking, the microphone is
best placed on a level surface, however, it can also be placed on a sloping surface of no more
than 45 degrees incline.
External Monitor Placement Considerations
If you choose to use an external monitor with your robot, it should normally be placed within the
robot's actual field of interaction, so that the robot can reference the screen, by looking at it.
The monitor should also be placed such that the brightness of the screen will not interfere with
the face projection of the robot. The placement of the monitor needs to be in line with the use of
the monitor in the skill. E.g. if the user is supposed to cooperate with the robot on the content
displayed on the monitor, the monitor should be placed at an equal distance from the user and
