HDK Health and Safety

We want you to enjoy using the Haptics Development Kit (HDK-REC192) safely. Detailed information relating to Health & Safety can be found on this page.

Please read the information carefully and make sure that anyone else using the kit does so before using it.

Before you start using the Haptics Development Kit (HDK-REC192) Read the information contained on this page in full. If you have a pacemaker, implantable cardioverter defibrillator (ICD) or other medical device installed or if you are pregnant, elderly or suffer from a heart condition, hearing problems or other serious medical condition which could be affected by ultrasound, please consult a doctor before using the Haptics Development Kit (HDK-REC192).

Device touch temperature

The Haptics Development Kit (HDK-REC192) may become hot during use. This most commonly occurs when the device is set to emit haptics for long periods of time at high ambient temperatures. This is normal and does not usually indicate a fault, however we recommend exercising caution, limiting uninterrupted usage and letting the device cool off before handling it.


Every time you use the Haptics Development Kit (HDK-REC192): We advise that the Haptics Development Kit (HDK-REC192) is placed on a horizontal surface, is in front of you and there is room to rest your elbow during use. The haptics technology is designed for short bursts of feedback. Continuous feedback from the haptics system, or any other vibratory feedback system, can lead to a temporary loss of sensitivity in the frequency range of the feedback. If this happens, take a 10 to 15-minute break. Each person is different, so take longer breaks if you need to. The haptic feedback is created by a region of high-intensity ultrasound. Do not target the feedback directly onto your ears or eyes. We recommend that you do not place your head directly above the Haptics Development Kit (HDK-REC192). We also recommend allowing for approximately 30cm between your head and the area of feedback generated by your hand.

If you feel unwell

Stop using the Haptics Development Kit (HDK-REC192) if you feel any of the following symptoms: dizziness; disorientation; impaired balance; nausea; light-headedness; headaches; involuntary muscle twitches; discomfort or pain in the hand, arm or head; drowsiness; fatigue or any symptoms similar to motion sickness. Do not drive, operate machinery or engage in other demanding activities that have potentially serious consequences until you have fully recovered from any symptoms. Do not use the Haptics Development Kit (HDK-REC192) until all symptoms have completely subsided for several hours. Seek medical advice if you have serious and/or persistent symptoms or any concerns.

Repetitive strain injury

Frequently repeating similar movements can make your hands, muscles, joints or other parts of your body hurt. If you experience discomfort, stop and rest for several hours before resuming use of the Haptics Development Kit (HDK-REC192). If you continue to have any symptoms, please stop using the device and seek medical advice.

Radio frequency interference

The Haptics Development Kit (HDK-REC192) can emit radio waves that may affect the operation of nearby electronics, such as cardiac pacemakers, defibrillators and other medical devices. Operate the device at a safe distance from medical devices and if you have a pacemaker or other implanted medical device, do not use the Ultraleap Haptics Development Kit (HDK-REC192) without first consulting your doctor or the manufacturer of your medical device.
