In this case, the attacker doesn't necessarily need you to touch the keyboard or anything. Their attack scenario is the following:
1. they send you an email with specific content and encrypted using your public key.
2. your email client fetches the email
3. the moment the client decrypts it (e.g. using Enigmail in Thunderbird), they can infer your private key just from the CPU's EM radiations.
4. Profit !!
Besides, their hardware is very small (as in "fits in a pocket"), and quite cheap (as in less than 300$) compared to what (they claim) existed before.
