At the 2018 AES International Conference on Audio for Virtual and Augmented Reality in Redmond, WA,
AuSIM announces a new product for collecting Head-Related Transfer Function (HRTF) data that meets
the enhanced needs of commercial VR and AR applications.
The needs observed are:
- Global Application
To meet the large world market for VR/AR, HRTF's must be collected and understood from every demographic including young and old, and every DNA pool.
- Big Data
With modern compute and storage, high-resolution data can be analyzed.
Higher-resolution requires better data integrity.
- Deep-Learning
Modern artificial intelligence (AI) technology provides the means to correlate
easily-recognized human characteristics with specific HRTF features.
However, AI is dependent on the two bullets above.
The challenges addressed to meet these needs are:
- Accuracy and Integrity
While HRTF accuracy and integrity is definitely contingent on the equipment and software quality,
they are also dependent on subject pose quality, which degrades with fatigue.
- Speed
Speed performance yields two benefits: more data and better quality due to less fatigue.

HeadZap-M
The product name HeadZap-M is derived from "HeadZap-Mechanized", a physically-automatic version of
HeadZap™.
Both azimuth and elevation axes are fully-automated with industrial automation controls.
Tracking, targeting, sensing, and monitoring technologies have been tightly integrated to
facilitate precision and speed.
The software has been optimized to deliver fast feedback for both operator and subject.

Background
AuSIM has been developing commercial HRTF measurement systems for 26 years,
dating back to
Dr. Jonathan Abel's Snapshot system
originally produced by Crystal River Engineering in 1993.
The technology behind Snapshot was patented by Dr. Abel and Scott Foster with US patent
US5729612A.
In 2000, AuSIM produced its first HRTF measurement system,
called HeadZap™,
developed principally by
Dr. Agnieszka Roginska at AuSIM.

Technology
HeadZap-M™ combines all of the most effective techniques
learned from 25 years of HRTF measurement, plus innovative sensing, automation, and
display to overcome the observed inhibitors of speed and data integrity.
As emphasized in the original Snapshot patent,
HeadZap-M™ employs a single excitation emitter to ensure
the difference in impulse responses is direction only.

Product Status
The first HeadZap-M™ system has been operating at a customer site
for over six months with proven results.
AuSIM is preparing to make a batch build and now soliciting pre-order interest.
More details will be available at this site in the near future.
Please contact William Chapin at wchapin@ausim3d.com to be notified of information posting
or to ask direct questions.
The current HeadZap product is still available,
meant to be setup or dismantled in one hour, manually operated in its traditional means,
but now controlled by the all new HZM software.
