The New Sony HMZ-T3W Head Mounted Display – More of the Same

September 7th, 2013 · 8 Comments · 3D / AR / VR / HMD


If you were expecting Sony to bring something new and innovative rivaling what the Oculus Rift offers already in terms of immersion, then you will most likely be disappointed by the new Sony HMZ-T3W HMD device that the company has just announced. The HMZ-T3 is the third generation of 3D-capable HMD from Sony in their more recent experience that the company has in the HMD device market, as some years ago they have had other HDM devices as well. The new T3 does not add in the visual or immersion factors as it is still equipped with 1280×720 OLED displays for each eye and provides 45 degrees field of view, the same specs as the previous model had. And though not yet officially announced the device supposedly will use HDMI 1.4(a) frame packaging method for stereoscopic 3D support ensuring compatibility with the PlayStation 3 console and possibly the new PlayStation 4. And while the use of HDMI 1.4 interface for 3D makes it compatible for gaming in stereo 3D on PC as well, PC gamers will most likely want to wait a bit more for the consumer version of the Oculus Rift.

– Supplied accessories: In-ear headphones, headphones attachments (S/M/L), 2x AC adaptors, AC cable, 1.5m HDMI cable, ambient light shield, carrying case


So what is new in the Sony HMZ-T3W HMD device? Slightly different design, just a bit lighter and a wireless option and a mobile battery. The useful feature here is definitely the support of WirelessHD technology for streaming the video without cables to the HMD device if your hardware is also capable of supporting the WirelessHD technology (supposedly with very low lag). And in order to be able to loose the cables you will also need a battery, so that you will not have to use not only a video cable, but a power cable as well and the HMZ-T3W does provide that as well. The battery should be able to provide you with up to 3h for full wireless connection or up to 7h when using HDMI cable connection for the video, though you probably would want to use the full wireless option.

According to Sony the new HMZ-T3W Head Mounted Display will be available in November 2013 in Europe and the announced price in Germany is 1299 Euro and in the UK is £1299 Pounds, there is no price and release date yet available for the American market.

Sony’s Phone 3D Sweep Panorama Mode is a Real Disappointment

July 19th, 2012 · No Comments · General 3D News

Sony Ericsson and now only Sony has announced last year that they’ll be bringing the 3D Sweep Panorama mode on their smartphone lineup as well, a a special software function that allows the recording of stereoscopic 3D panorama photos with the use of a normal 2D camera. Previously this mode has been available on some of the company’s portable digital cameras and there it was not performing that bad actually, so I’ve had some hopes for the functionality brought to smartphones. Just as a reminder, Sony still doesn’t have a full fledged 3D-capable digital camera targeted at consumers, though the company offers 3D digital camcorders like the portable 3D Bloggie or the Sony HDR-TD10 and the newer Sony HDR-TD20V. For digital cameras and apparently smartphones as well the company remains in 2D and only offers the 3D Sweep Panorama as an extra that you can use together with a 3D HDTV if you own one.

I’ve already explained in an article how the 3D Sweep Panorama mode works on digital cameras and the principle for it on smartphones is essentially the same, though due to the smaller camera sensor you should not expect that good results as when using a Sony digital camera. I just recently took a friends Sony Ericsson Xperia Arc S smartphone to do a quick test of the stereoscopic 3D capabilities that the smartphone might be offering and to see if it can actually be used in 3D for something else besides the 3D Sweep Panorama mode. You know, I was interested in the 3D Sweep Panorama when it was made available at first on the digital cameras, but my expectations from it being introduced on smartphones weren’t that big, so I was not in a hurry to try it… and apparently I was right not to.

When the 3D Sweep Panorama mode was announced that it will be made available on Sony Ericsson’s upcoming smartphone lineup I personally expected that this would mean HDMI 1.4 3D support and actually also being able to do other things in 3D with the smartphone when connected to an external 3D-capable display. Unfortunately it did not happen this way as I’ve just found out, the Xperia Arc S for example does not support HDMI 1.4 output in 3D, instead the phone outputs 3D in Over/Under mode essentially splitting the screen in two. So when you connect it to a 3D HDTV and open up a 3D panorama photo you have to manually switch the TV set into Over/Under 3D mode and that simply means that you get half of the vertical resolution of the smartphone’s screen. Yes, you’ve got that right the Xperia Arc S has a screen resolution of 854×480 pixels (in Landscape mode) and in stereoscopic 3D photo output mode you get just 854×240 per eye – pretty low quality or with other words blocky-looking image with low resolution and not very good stereoscopic 3D effect on top of that. And of course the fact that you are not being able to lets say play a 3D video from the phone on an external 3D HDTV or use it for pretty much anything else in stereoscopic 3D mode is really a big disappointment. So my advice is just not to pay any attention at all to the 3D Sweep Panorama mode you get available on Sony Ericsson and the upcoming Sony smartphones, should you consider to get such a device, just forget that it has support for something 3D in it.

Sony’s EX720 Series of 3D HDTVs Not a Good Choice for 3D Use

March 5th, 2012 · 18 Comments · Other S3D Tech

If you were planning to go for one of the more affordable 3D HDTV series from Sony, namely the Ex720 series that offers 3D-capable TV sets with size of 32, 37, 40, 46, 55 and 60 inches and you want to actively use this television set for 3D, then you better not. I’ve read some people complaining that the 3D effect is really bad on this lower-end series from Sony due to the presence of a lot of crosstalk, but I was not expecting that it is so bad. Recently I’ve played a bit with the 46-inch version of the EX720 (Sony KDL-46EX720) and I was surprised to find that the situation with the level of crosstalk is so bad, it is way more than you would expect to see on a 3D HDTV. It is probably even worse than on the first generation of 3D Vision-ready monitors that came out a few years ago, and you’d probably not expect that from a more recent 3D HDTV (the models from EX720 series were introduced last year), the level of crosstalk you get in 3D mode on the EX720 totally ruins the 3D experience. So my advice would be to stay away from the Sony EX720 series if you are planning on using these in 3D mode, and there is not much reason to buy this model if you are not going to take advantage of its 3D capabilities. If you are looking for another 3D-capable solution in that price range, there are quite a lot of other options that will provide better 3D experience – passive 3D solutions from LG or active from Samsung for example. And if you are already an owner of an EX720 3D HDTV from Sony, you are welcome to share your feedback from how your 3D HDTV works in stereo 3D mode and if you are happy with the result. I’ve spent a few hours trying to tweak the settings of the 46-inch EX720 TV set and as a result got a very slight improvement, but the end results were still very far from satisfactory. There seems to be no new firmware updates addressing the bad 3D performance for the series available yet, and I’m not sure if it would be possible to get better results via a software update only, maybe the LCD panels being used are just not good choice for 3D and that is the cause of the problem. So my advice would be to just stay away from Sony’s EX720 series of 3D HDTVs and instead go for another brand that will provide better 3D experience within the same price range.
