Subjunctives are considered to be unclear in patent claims. Both claims can be lost by finding a citation that only has the system, or only the method.

The system here is basically a normal video presence system. But the claims specify the camera is at ~3 feet (whilst a normal video presence system will have the camera at average eye-level). That's the only part that might be hard to find a good citation against [in the allowed time] IMO.

The yoga parts are all non-technical elements so they add nothing.

Given the system is all well-known tech the method is all you've got.

That said the claims have a ring about them of not having been done by a highly skilled patent attorney.
