We at Ultrahaptics believe our technology has numerous applications in Human-Machine Interaction (HMI) from gesture control in cars, home appliances, industrial and medical environments to creating rich and immersive VR and AR experiences. We offer our Evaluation Program and TOUCH Development Kit as a way for you to experience Ultrahaptics and to develop and integrate this unique technology into your applications.

General Points

You should consider the form factor of the transducer board, power requirements, the size of your interaction space and portability of the application in your design. Any tracking device will need good line-of-sight to identify the hand clearly and without obstruction. The ultrasound array itself should not be obstructed by any solid objects, while acoustic reflections should be considered when building the array into a confined space. For example, reflections from nearby, hard surfaces may have a detrimental effect on the acoustic field.

While sensations can be felt from 5cm from the array surface, the Ultrahaptics array works best at distances greater than 15cm and out to about 30° either side.

To protect from damage, dust and spillages the array should be covered with a suitable material. You can purchase the optional cover materials pack, UHDK5-CM1, for use with the TOUCH Development Kit, to assess a selection of hard and soft options. The same materials can be used with UHEV1 but we are happy to offer advice or evaluate any materials for you as part of our engineering services.

Remember to account for cabling and the location of the host computer.

TOUCH and Evaluation Kits

While the Ultrahaptics TOUCH Development Kit (UHDK5) and Evaluation Kit (UHEV1) are not designed as end user products, they are well suited for integration into a demonstration or proof-of-concept application.

The UHEV1 can be mounted directly in a suitable solid structure while the UHDK5 can be removed from its frame and anchored using the four corner attachment holes. Note that if the relative position of the tracking device is changed a new alignment definition file will be needed. You can find details of how to do this in the SDK documentation.

In addition to the standard, square array form factors we provide the rectangular UHDK5-AA1, 24×8 transducer board for UHDK5, and an optional 28×9 transducer array suitable for use with the UHEV1*.

Ventilation

Due to the heat produced from the transducer board, both UHEV1 and UHDK5 must have suitable ventilation, one of the reasons the UHDK5 kit is mounted in its distinctive frame. If placed inside a closed environment additional ventilation should be considered. To protect from overheating the UHDK5 is designed to go into a transducer standby mode. In this state, the device will still appear and communicate with the host machine but will not output ultrasound. Normal operation will resume once the device has cooled sufficiently.
