  Forthcoming 6G networks have two predominant features of wide coverage and
sufficient computation capability. To support the promising applications,
Integrated Sensing, Communication, and Computation (ISCC) has been considered
as a vital enabler by completing the computation of raw data to achieve
accurate environmental sensing. To help the ISCC networks better support the
comprehensive services of radar detection, data transmission and edge
computing, Reconfigurable Intelligent Surface (RIS) can be employed to boost
the transmission rate and the wireless coverage by smartly tuning the
electromagnetic characteristics of the environment. In this article, we propose
an RIS-assisted ISCC framework and exploit the RIS benefits for improving radar
sensing, communication and computing functionalities via cross-layer design,
while discussing the key challenges. Then, two generic application scenarios
are presented, i.e., unmanned aerial vehicles and Internet of vehicles.
Finally, numerical results demonstrate a superiority of RIS-assisted ISCC,
followed by a range of future research directions.
