Avi Bar Zeev, a manager on Apple’s secret augmented-reality headset team, said on Monday that he left the company.

Bar-Zeev joined the company in 2016 as Apple ramped up its hiring to build an AR headset and served as a senior manager on the team, Bloomberg News reported last year. On his LinkedIn profile, which disclosed his departure, Bar-Zeev said he led ‘experience prototyping for a new effort’ and ‘developed key prototypes to rapidly prove concepts.’

The former Google, Amazon.com and Microsoft manager said on Twitter that he ‘had the best exit one can imagine’ and ‘won’t comment on any specific product plans.’ Former Dolby executive Mike Rockwell runs Apple’s AR team as vice president of augmented and virtual reality.
