  Cyber human interaction is a broad term encompassing the range of
interactions that humans can have with technology. While human interaction with
fixed and mobile computers is well understood, the world is on the cusp of
ubiquitous and sustained interactions between humans and robots. While robotic
systems are intertwined with computing and computing technologies, the word
robot here describes technologies that can physically affect and in turn be
affected by their environments which includes humans. This chapter delves into
issues of cyber human interaction from the perspective of humans interacting
with a subset of robots known as assistive robots. Assistive robots are robots
designed to assist individuals with mobility or capacity limitations in
completing everyday activities, commonly called instrumental activities of
daily living. These range from household chores, eating or drinking to any
activity with which a user may need the daily assistance of a caregiver to
complete. One common type of assistive robot is the wheelchair mounted robotic
arm. This device is designed to attach to a user's wheelchair to allow him or
her to complete their activities independently. In short, these devices have
sensors that allow them to sense and process their environment with varying
levels of autonomy to perform actions that benefit and improve the well-being
of people with capability limitations or disabilities. While human robot
interaction is a popular research topic, not much research has been dedicated
with regard to individual with limitations. In this chapter, we provide an
overview of assistive robotic devices, discuss common methods of user
interaction, and the need for an adaptive compensation framework to support
potential users in regaining their functional capabilities.
