Hello  I am a bit of a newbie looking for a stereoscopic display system that I can use for watching stereoscopic videos on a laptop (no dual gpu card and with LCD monitor). I have to make a decision as to which display to go with and I am a little stuck at the moment. I was hoping that one of the many experts in here maybe has some advice to spare. It would really be a great help to me. I am working with an underwater robot build to monitor the condition of the Great Barrie Reef. The robot records video sequences of under water reef enviroments with a pair of stereo cameras. I would like to see these videos when I am on boat field trips testing the robot. The resolution of each image is 628 x 582 and approx 43 HFOV and 33 VFOV. I have been reading through this forum for quite a few days now and I am still unsure which solution is the best for my project. There is much good advice in here for HMD used for gaming and for shutter glasses and CRT monitors/projector for 3D video display on a full screen. However, my problem falls a bit out of both categories. The problem I am facing is selecting a one-person display that can show fair quality stereoscopic video sequences from a laptop. I would like fair colour fidelity and no head-aches during the usage of the display My problem seems to be: 1) My budget is approx AUD2000, might be negotiable though... 2) I need to be able to run the system from my laptop computer 3) I need to be able to watch the video outside 4) I need to be able to have clear images so that I can see details in the recordings I have researched all sources I have been able to find on google and on various forums. It seems that a HMDs/FMDs would be a good solution. I have contacted CyberMind, Inition and I-O System Displays, however, since I am in Australia, I have not been able to get demos of the displays -and of course, all of them offer something perfect for my application according to the salesmen ) So... I am still very unsure of what display to go with and if an affordable HMD/FMD can deliver what I need (I have never tried using a personal display before so I have no experience to make my decision upon). Therefore, I would greatly appreciate any advice that can help me choose among the many display technologies available, or maybe give some feedback on how usable the different HMDs/FMDs would be. Many many thanks! /Maja | ||

Generalay no system for 3D visaulisation on LCD screen (laptop) looks good in comparison to active system visualziation on CRT monitor or active 3D projection by DLP projector ... If you serch for quality, no hedeakes, clear and contrast colors, no ghosting, you should re-thing your concept ... What about a laptop with Quadro card and active 3D DLP projection ?

Hi, the cheapest possibility were: Laptop with NV Card (NX6600), NVidia 3D stereo drivers, shutterglases from e-dimensional,stereo player and stereomultiplexer from P.Wimmer (www.3dtv.at) and old bigger color CRT and DYI built case for CRT for use this in dark emwiroment (and generator .-() This is I think cheapest possibility. Other possibility is use of Z800 (low picture qality). | ||

Thanks a lot for your feedback, I appreciate it. Husakm: The boat we are on is a dive rubber boat, so a projector wont work well. Husakm and Hornet: I am considering the shutter glasses and CRT + water proof case option, however the requirements reg. portability and high luminance levels will most likely not make the system work well outdoor -and i would very much like that. Reg. HMDs have any of you tried wearing the Z800 outdoor? I am also considering the i-glasses 3D Pro, because FOV is not a big issue for me, however image quality and the ability to adjust the optics to more than one use easily is. The source resolution is only 628x582 so 800x600 should be fine for my purpose. If the diagonal FOV is 28 as for the i-glasses then the angular res is less than 28*60/800=2.1. So, the i-glasse should be good for reading text and so also for seeing details in the image, do you agree with this? anyone tried the i-glasses for such tasks? I am still a it afraid that the image in the eyeglasses is too small for proper viewing? Reading several discussions on z800 vs i-glasses it seems that most users use these for gaming. Has any of you experiences with watching video with them both? I am also considering the option of the more expensive TriVisio 3Scope, but I cant find any user reviews on them http://www.inition.co.uk/inition/product.php?URL_=product_hmd_trivisio_3scope&SubCatID_=16 Also, the 5DT 800-26 is an option (maybe even a better one considering ooutdoor viewing, since the glasses looks like they can close around the eyes making it darker for the outdoor conditions) http://www.inition.co.uk/inition/product.php?URL_=product_hmd_5dt_HMD800&SubCatID_=16 However, no luck reg reviews there either. Is there anybody in this forum who has any experience with these HMDs? If yes, how superior do you think/experiense (if any) these two HMDs are to the Z800 and i-glasses?? What about comparison to shutter glasses and a crt monitor? Damn, its difficult without any experience to make the decision upon. its a lot of money  One last question for the experts!  What graphics card do I need for the single output z800, i-glasses and 5DT? will a NX6600 also drive these? is it possible to add the graphics card to my current laptop, T40P, or will it conflict with the integrated radeon card? (even though i do study computer science im more of a math nerd than a hardware nerd ) ) if I am to run the 2 channel trivisos what graphics card can i then use? i find, that the nVidis Quadro go 1400 is a tad expensive... Thanks for your comments on this post! :-) | ||

Hi I think, the biggest qestion is the output format of video from this robot, is this digitall, or analog. Dual stream, or single stream (analogue cameras) Other qestion is:were the video recorded?, in cameras, or in laptop?(digitally) when the source is analogue video is cheapest and simplest use of display vith analogue inputs. | ||

Thanks for your answer Hornet. the output from the robot is digital and the output I display will not come directly from the robots but from a laptop. Whether I output a stereopair in dual (if I get a dual graphics card or a splitter) or single channel is up to how I program the final solution. I think I would be able to accommodate any format. I know it was a lot of questions I posted at one time but since I am considering the i-glasses I would very much like to hear if any of you have had any experiences with video display and text reading? is the image too small for prober viewing? The reviews I have found are written with regards to online gaming . I was also thinking about the following solution: 1) triViso 3scope 2) a laptop with 1600x1200 res running usual 60Hz 3) my own stereo format displaying stereopairs side by side 4) Matrox dual2go splitter -> splits the output 1600x1200 image into two vga outputs each of 800x600 in 60Hz. I assume it also does the dvi-vga convertion... will have to look into that. has any of you got any experiences with such a solution? I think it sounds promising... can you see any problems with the solution? thansk a lot! | ||

Hi,have this readed, please see too: Sharp Announces Second-Generation 3D Notebook 3D-News Posted: Wednesday, March 9, 2005 (0:12 UTC) | Posted By: Webmaster Powerful Actius AL3D Notebook Features Sharp's 3D LCD Screen Technology, Eliminating Need for 3D Glasses Following a wake of awards and recognition for the Sharp Actius Notebook line, Sharp Systems of America today announced the availability of the Sharp Actius AL3D. Featuring Sharp's 3D LCD Screen Technology, the Actius AL3D represents Sharp's second generation of 3D Technology-enhanced notebook systems. Building on the foundation laid by its groundbreaking predecessor (the Actius RD3D), the Actius AL3D represents a significant step up in power and style for Sharp's 3D notebook line. Powered by Intel's brand new Pentium® M Processor 750, the New NVIDIA® GeForce(TM) Go 6600 graphics processor with 128 MB Video RAM, and stocked with 1024 MB of DDR2 SDRAM, the powerful Actius AL3D is geared for high-end mobile performance. "The Actius AL3D offers high-end power and functionality, providing users with some of the most advanced computing technology available in a very attractive package," said Ian Matthew, 3D Business Development Manager at Sharp Systems of America. "Viewed on the impressively bright LCD screen that the Actius AL3D possesses, Sharp's 3D LCD Technology provides users with a superb three-dimensional visual experience that is crisp, clear, and precise." Sharp's 3D LCD Technology Developed jointly by Sharp Corporation and Sharp Laboratories Europe, Ltd. (SLE), Sharp's TFT 3D LCD Technology provides a significantly enhanced visual experience by offering a realistic sense of depth and presence. Unique to Sharp's 3D Technology, the Actius AL3D display can be easily switched between 2D and 3D display modes at the touch of a button, providing a flexible working environment that takes full advantage of both 2D and 3D applications. The 3D effect is achieved using a parallax barrier technique to separate light signals. Light from the LCD is divided so that different patterns reach the viewer's left and right eyes. The direction in which light leaves the display is controlled so that the left and right eyes see different images. When centered in front of the display, each eye receives the correct visual information for the brain to process. This makes it possible for the image on the screen to appear in three dimensions without the user having to wear special goggles. "Sharp's TFT 3D LCD technology works on the principle of displaying left and right eye views that are separated so that the left eye sees only the left eye image, and the right eye sees only the right eye image," explained Ian Matthew, 3D Solutions Business Development Manager at Sharp Systems of America. "Since these images have perspective and are offset in the same way that the human eye normally sees the two images, the brain naturally interprets the image disparity and creates a 'sense-of-depth' effect. The result is a 3D, 'out-of-screen' display that provides users with a visual experience previously unattainable without polarized or liquid crystal shuttering lenses." Target Markets Aimed primarily at the professional market, the Actius AL3D is targeted toward market segments that are already familiar with 3D solutions using Shutter Glasses and page sequential display mode, which are widely supported on PC using both Windows and Linux. Medical Market: Use for 3D computer modeling for diagnosis has increased tremendously over the last 3 years. Software tools now make accurate computer models from MRI data and other methods, and these models are providing very powerful analysis tools. With the increase in complexity of the computer models being generated, new visualization techniques are in demand to improve analysis. With the Actius AL3D, Sharp offers 3D stereoscopic visualization, without the need for glasses, in a mobile environment. These same modeling tools are now being applied in the area of surgery preparation. In conjunction with haptic devices, which offer resistance feedback, surgeons are provided with a realistic practice environment where difficult procedures can be safely practiced, leading to better-trained surgeons and faster surgeries. Pharmaceutical Market: Computational Chemists have been using 3D viewing as part of the drug synthesis process for many years. Now, Medicinal Chemists are employing 3D visualization techniques in the experiment process to create synthesized drugs. Sharp's Actius AL3D provides these chemists 3D visualization in a mobile computing environment for their experiments. In addition, the Actius AL3D takes up a smaller footprint than traditional CRT 3D solutions, allowing researchers to take back valuable lab space. Educational Market: 3D visualization is finding its way into the classroom for K-12 as well as Universities and schools of higher education. Sharp has partnered with companies such as EON Reality, Inc., Emergence, and JTM to provide 3D platforms for teaching environments and for high-tech labs in the education field. Oil & Gas: Scientists in petroleum exploration and production are using 3D visualization techniques to more accurately understand the complex geometry of oil reservoirs and to provide real-time input for navigating new oil drilling. The mobile platform offered by the Actius AL3D allows production engineers in the field to acquire real-time data and control the drilling process more accurately. Manufacturing: Advanced 3D visualization is a boon for manufacturers of all types, including automotive and aerospace, by providing three-dimensional virtual prototyping. By using 3D tools to verify the designs created on CAD systems, designers are able to scrutinize their designs in a 3D environment using virtual models and cutting down on the amount of defects before physical prototypes are created. Using the ability of the Actius AL3D, cycles between design and manufacturing can be reduced, significantly cutting time to market and development costs. Consumer Market: Though aimed primarily at the professional market, significant progress has been made toward the consumer adoption of 3D Technology. NVIDIA Corporation has added stereoscopic display support for the GeForce series graphic processors, enabling over 1,000 games to take advantage of 3D viewing on Sharp's 3D LCD displays. Additionally, the Actius AL3D ships with the TriDef® DVD Player, created by DDD Group plc, which provides on-the-fly 3D conversion of any DVD movie. The Actius AL3D -- Powerful Mobile Computing & 3D Visualization Designed with the high-performance demands of 3D applications in mind, the Sharp Actius AL3D is equipped with the Intel Pentium M Processor P750 (1.86GHz) and driven by Microsoft® Windows® XP Professional operating system. The notebook is equipped with 1024 MB of DDR2 SDRAM, and comes complete with an 80GB (a) Serial ATA hard drive. In order to provide the advanced visual processing power for 3D applications, the Actius AL3D comes equipped with the NVIDIA® GeForce(TM) Go 6600 graphic processing unit driven by PCI Express for faster bus performance with 128 MB of dedicated graphics memory.

The Z800 is really the only solution for your application. (www.z800.com) The others HMD you identified is pretty much a prototype and won't give you the performance you can get from the Z800. Bang for your buck, the Z800 wins everytime. (Message edited by tekgear on August 30, 2006) | ||

...Tried sending this a week ago, but my Stereo3D account is %$&^*&'d up right now, so I've got an alternate... I don't know what resolution your laptop is capable of, which has some bearing on the available quality, but the main obstacles I see in your situation are 2 things: 1. Brightness/Contrast of the display system, particularly as regards being outside in sunlight. 2. Portability First, I would think that ANY laptop display being shown outside in sunlight is going to have a hard time competing with the sun--Stereo or NOT. So, my suggestion is a low-tech one... Get a hood/cover for your laptop display screen, black with top shade and possible side shades. While you're at it, make it possible to add in a "barrier" between the left and right halves of the screen (velcro or something). Now, use Peter Wimmer's Stereoscopic Player, set to Freeview/Parallel, Show at "Fullscreen/Resized" and you've got yourself a home-made "Stereoscope/Stereopticon". How good it works depends mainly on how well you can focus on the screen at the distance of the barrier's depth. If you need to do this live, you could also get his "Stereoscopic Multiplexer"... If this doesn't work, you'll still have a very good sunshade for your laptop, and you can continue to pursue the HMD route. Scott | ||

Scott Warren's last comment made me think about a system I've seen. It's the Screenscope by Berezin. There's a version for laptops arond 200 usd. It's "simple clamp and play"! You have to provide side-by-side images and it makes a stereo pair. No power needed, portable, cheap, hopefully well made. It does cut the screen in two, though. I wasn't sure about how to provide side-by-side images, so I was not thinking much about this item. With Scott saying that Stereoscopic Player does that (and with the sunshade), you might be set. Have you considered a discussion with Andrew Woods' group (fellow Australian) ? http://www.3d.curtin.edu.au/ (lol, maybe you work with him!) Note: I am currently building a lo-cost station for data visualisation. I am just trying to figure the right pieces; I am not an expert! |
