EBay's Innovation and New Ventures group, run by former eBay mobile executive Steve Yankovich, is taking part in the Google Glass trial program, she added.
EBay's online marketplace has been revitalized in recent years by the success of apps the company developed early for Apple Inc's iPhone, the first mobile computing platform to really take off commercially.
EBay wants to make sure that, if Google Glass becomes the next big mobile platform, its apps will be on there early too.
Some of eBay's existing mobile apps already let shoppers point smart phone cameras at products to check online prices and buy related items. The price-checking capabilities have sparked a new trend in retail known as show-rooming, the practice of looking at items in physical stores and then buying them online.
Google unveiled a half-dozen apps on Thursday designed to work on Glass, a stamp-sized electronic screen mounted on the left side of a pair of eyeglass frames that can record video, access messages and retrieve information from the Web.
Glass apps from social networking services Facebook Inc and Twitter were among those announced on Thursday.
