Band: opinion spread · Dot: weighted average
Sources split: every reviewer and video found the hand tracking accurate and lag-free, while a sizeable group of owners report calibration trouble, gestures that drop out, and tracking that degrades during a session. Reviewers also agree each gesture means lifting a hand off the keys, and that gestures can bleed into one another.
Measured
ROLI specifies infrared cameras tracking 27 joints per hand at 90 frames per second; SoundGuys reports two Ultraleap IR 170 cameras with a 100–1000 mm working depth. ROLI’s FAQ asks for the keyboard to be within 70 cm and centred, with reflective surfaces removed and lighting or clothing adjusted if hands aren’t tracked.
vs. listeners — The positive verdicts come from review loans and demos (SoundGuys used a prototype at a ROLI-hosted session); the failures come from owners’ own rooms and hosts — iPads in the Learn app losing tracking after 5–20 minutes, and Windows machines. ROLI’s own FAQ list of lighting, clothing and reflection conditions suggests the environment explains part of the split.
“the camera tracking is incredibly accurate and also without latency, so everything feels pin-sharp.”

“Nevertheless, the calibration never completes and the device is pretty limited in the end, although working from an hardware point of view.”
