ITEC 2017: GBvi premieres Chronos Greyscale on Canon and Sony stands

Last week’s ITEC show in Rotterdam, the Netherlands was a huge success – thanks to all who stopped by our stand.

The trend of an increased need for optical blending to maximise dynamic range in projected display systems continues.

Chronos Greyscale – our new optical blend technology capable of blending 4K laser phosphor projectors was demonstrated on Canon and Sony stands – this specialist solution will be available from Q3 2017.

 

The technology works with true greyscale, 4K+ resolution projectors and is laser phosphor compatible with low light loss.

David Cotterrell’s 2nd Exhibition of Mirror III using GBvi’s VOID comes to close at Danielle Arnaud, London

For his fourth solo exhibition at the gallery, David Cotterrell presented three works from the Mirror project: a series of two-screen works produced in collaboration with Ruwanthie de Chickera at London’s Danielle Arnaud Gallery.

The travelling exhibition was open from 25 February to April 1.

Mirror III: Horizon examines what might transpire between two strangers if their communication was reduced to the language of lights. Filmed in Malta, set against the dramatic edges of the island’s stunning coast and contextualized by the island’s deep historical experience of visitors who arrived repeatedly by sea, the installation draws on the fluctuating paranoia of the current refugee crisis. Mirror III examines what might possibly be communicated between strangers if their words were reduced to beams of light and their faces need never be revealed.

The art installation comprises two VOID installations by GBvi, each presenting video media of a Pakistani guard communicating with the other in the secondary VOID. A suspended dome speaker above the installation ensures visitors only experience both sight and sound when underneath the audio and between each of the VOID stations.

VOID, an infinity display experience for educational spaces, attractions and themed experiences, uses special display techniques and light path management to create extreme depth cues and illusions of distance – so that viewers and audiences are provided with a sense of peering into space.

“It’s very difficult to transfer the sensation of place into reality. People can’t understand or recreate this experience from an illustration or image alone and we wanted to generate a sense of emotion and understanding from this installation. The VOID allowed us to do just that.” explains artist David Cotterrell.

“It was important that visitors became fully immersed and engaged with the media. We will continue to use this technology and refine how we apply it in future installations to continue innovating with depth cues and immersion in art.”

Available in a range of size, brightness, projection performance and playback configurations up to ultra-high contrast 4K, VOID is built to deliver realistic, immersive experiences.

ITEC 2016 – great to see all

The GBvi team has returned from a great ITEC 2016 event in London. We met up with many faces old and new and are excited to continue being a part of such a vibrant and innovative industry.

See you again next year, if not at another event until then.

GBvi to speak at ITEC 2016

ITEC 2016 is the annual forum where representatives from across the military, industry and academia connect and share knowledge about military simulation, training and education community. For more information on ITEC 2016, click here.

Geoff’s ITEC 2016 presentation is titled ‘Optical Blending – Difficult yet Essential for Maximising Dynamic Range of Projection Displays’

 

Here’s a snippet of the abstract…. For full details or to request a copy of the presentation, please contact us

 

Quality projection displays for visual simulation have evolved to use mainstream commercial projection devices, which, together with automatic alignment solutions, have dramatically reduced time required for their installation, alignment and maintenance. However, one bugbear has remained in the form of projector light leakage when displaying dark scene content.

Electronic blending solutions exist that produce excellent results for bright scenes but, for continuous background intensity levels in dark scenes, one must use infill techniques that sacrifice precious dynamic range. Often, solutions are commissioned that sacrifice up to 75% of the possible dynamic range, on the basis that ‘it’s the best you can get’. Often, this trade-off is not even apparent to the end-user, who therefore understandably assumes that the resulting performance really does represent the state of the art, which in turn limits the useful application scope of an expensive simulation system. Optical solutions to blending multiple channels can solve this problem, offering the promise to increase the utility and hence value of visual simulation training substantially, yet often this option is not even considered – so why is this?

 

Factors limiting the take-up of optical blending include: –

 

  1. Difficulty: implementing optical blending has proven to be surprisingly difficult. While standalone projected image quality of commercially available projectors is often excellent, optical characteristics tend to be unsympathetic to simple solutions. A systematic and well-founded methodology can lower this barrier substantially.
  2. Higher contrast projectors are available: even displays employing some of the more recent high-contrast projectors would benefit from optical blending – almost to the same degree as lesser contrast examples, owing to the enormous perception range of the human observer over a wide range of viewing conditions.
  3. Cost: while cost of the display system is certainly increased by the addition of optical blending hardware, it is a low proportion of visual system cost and the performance enhancement can represent value well in excess of this increase. Optical blending implementations – which place physical masks in the projection light paths – have been around for a long time, but a universal solution for all projector types and scene content has yet to become available. Many solutions give relatively poor performance that can be tolerated for dark scenes such as those experienced in night training, so are actuated out of the light paths for use with daytime scenes. These present logistical challenges to simulator users, where a choice must be made as to what ‘mode’ you are training, or some transition must be suffered while the blending system switches mode. Other solutions cannot withstand sustained light flux without degradation, so again must be actuated, while yet others may cause image sharpness degradation in the blend regions, so must be designed very carefully to limit this impact, particularly with high-resolution projectors.

The purpose of this paper is to inform the simulator operator and trainee community of this key area of visual system optimisation, including its cost-benefit analysis. Included in this will be a review of the mainstream projection technologies and their respective pros & cons, particularly with regard to scene dynamic range and blend implications. This in turn leads to a detailed review of optical blending options, presenting their operating theories and application scope. Finally, a new active optical blend technology is introduced that widens the range of display types that can benefit from high quality optical blending.

GBvi at ISE 2016 with 7thSense

This year, the biggest yet for ISE 2016 in Amsterdam, GBvi will be exhibiting for the first time in partnership with 7thSense Design.

The annual show will take place from Tuesday 9th to Friday 12th February at the Amsterdam RAI and is expected to attract over 70,000 visitors.

On show, we will have our brand new product release ‘The Void’ – being premiered for the first time. Designed for attractions, classrooms, science centres, museums, this versatile infinity viewing pod system is built for the next generation of immersive experiences. Drop by the stand to find out more.

We will also be actively seeking international reseller partners for Chronos optical blending technologies.

You can find us on the 7thSense Design stand in Hall 10 (10-Q116). You can navigate your way around the show in advance via the interactive floorplan.

Get in touch if you would like to arrange a meeting during the four day show.
