Method and device for computing computer-generated video holograms

The data defining an object to be holographically reconstructed is first arranged into a number of virtual section layers, each layer defining a two-dimensional object data sets, such that a video hologram data set can be calculated from some or all of these two-dimensional object data sets. The first step is to transform each two-dimensional object data set to a two-dimensional wave field distribution. This wave field distribution is calculated for a virtual observer window in a reference layer at a finite distance from the video hologram layer. Next, the calculated two-dimensional wave field distributions for the virtual observer window, for all two-dimensional object data sets of section layers, are added to define an aggregated observer window data set. Then, the aggregated observer window data set is transformed from the reference layer to the video hologram layer, to generate the video hologram data set for the computer-generated video hologram.

Hot Spot Use in Advertising

InactiveUS20110178875A1Maximize available for ad viewingReduce areaMarketingDisplay deviceWorld Wide Web
The delivery of targeted advertisements (ads) to wireless mobile handheld display devices (MHDDs) with client specific advertisement and dynamic content for response and feedback is becoming important in advertising. As the return for ads on MHDDs becomes higher, there is a push to show larger and more interactive ads on devices that have small displays. This has created a need to maximize the area available for ad viewing. The need for larger viewing area reduces the area available for call-to-action response enabling switches or inserts on the screen for customer interaction. To overcome this deficiency and provide the necessary end-to-end response capability, hot-spots on the ad image are provided as call-to-action response regions without limitation on the ad viewing area. The use of such hot-spots provides users of MHDDs a preferred interaction mechanism for responding to the advertisement, while maintaining a large ad viewing area.
