I recently did some work as a tester with mobile devices (wap phones, palm, winCE). These devices are really plagued by inadequete input/output capabilities. Despite market hype regarding wireless internet and wireless device, no one is really going to use these things because you cannot input information quickly enough and the resulting output images end up on miniscule, low-res screens. Inputs aside, I have always thought that the first low-to-mid-cost HMD which could be applied to a mobile device would really open the doors to mobile device applications (even if existing input technologies were all that was available). I searched through the list of topics on this discussion board, and I realize that this question is off-topic, but if anyone has any thoughts or information on the subject of HMDs and wireless data devices I would very much appreciate their contribution. | ||

My oven opinion is, that the sony Glastron and Olympus Eye Treek coud be used for the purpose you mention. The resolution is aprox. equvalent to 640x480 color monitor .... Somebody must only implement an graphic chipset with the proper output in the mobil devices ... I thing that the problem will be in the input interaction device - how to emulate an mouse on an mobil phone ? | ||

Michal, I think that inputs on phones might go the way of touch sensitive screens ala the palm computers. I think that interface is usable enough. Also, if you have seen some of the newer winCE devices like the HP Jornada, the screen resolution is pretty impressive. I guess it would make sense that a company like Sony, which makes PDAs and just about everything else for ordinary consumers, would move Glastron in that direction. I really think it would be a great move. Is the implementation of a graphic chipset difficult from a technical perspective? | ||

If you will use devices like Sony Glastron or Olympus Eyetreek (LCD screen galsses) the touch sensitve screen concept will not work. It will be vary funny to see people manipulating with a small pad on the phone and watching the result in the monitor/glasses :-) I do not thing that the graphic chipset will be any touble. Maybe that the trouble will be the power supply for biger LCD devices ... The combination of mobil phone working as an internet browser with monitor/glasses will be probably realy interesting device ... | ||

Have a look at http://www.MicroDisplay.com/ Side note : found this in MicroDisplay News Archive : November 29, 1999 - "Dominion Ventures Invests in The MicroDisplay Corporation" - at least we know now where the Vorta got their HMDs ;-) | ||

You're right Michal re: the touch sensitive impossibility. Sometimes I real surprise myself with my idiocy. However, I remember seeing a wearable computer at a Palm Pilot meeting at MIT where the mouse was gyroscopically maneuvered. Pretty cool. Andreas, do you think Microdisplay is a leader in this area? | ||

I guess you're talking about the low-cost standard Glasstron and EyeTrek, which have a resolution of 180,000 pixels. 640x480 on a LCD-HMD requires 921,600 pixels. 921,600 / 180,000 = 5.12 This means you're more than 5 times below VGA - and it shows! I once tried the EyeTrek myself. Christoph | ||

Interesting Discussion. The limitations of the wireless web are severe. Looking at a tiny little screen, trying to type on a number pad of a phone, etc. Do you think a monocular HMD with voice recognition as the i/o device would be a big seller? Steve@IIS | ||

At least, it made some nice TV commercial some time ago : a Yuppie, sitting alone among a load of pidgeons in a public place and wearing such a thing, apparently doing online trade by mumbling 'up,up,.. down..' and occasionally yelling 'BUY!! - SELL!!!' - always stirring up those poor birds. | ||

I know the topic is a bit dated, but on a similar note, i'm thinking about buying one of the eyetreks by olympus, but can't find any realworld information, only the normal useless prepared marketing garbage that doesn't do any good for getting an idea of what the product is like.. I used to have a pair of i-glasses (the originals. I kinda liked them at first. If memory works right, i think the displays worked at 320x240 highest but full color req'd half that. The eyetreks that have the 180,000 pixels.. i think (???) that is monochrome pixels and you have to divide by 3 (rgb) to find the number of real pixels which = 60,000, divide that by 200 = 320 meaning a color 320 x 240 display is that roughly right? From video, i remember that VHS is ROUGHLY comparable to a 320 x 240 display.. Does all that add up right? Anyone have any experience with the eyetrek as far as effective field of view? Would be nice to see some of these things before dropping $500 to $1000 but there is no place locally that i can find... Thanks, Rob | ||

Remember that commercial? Our Product will be on the market by the end of the year. 640x480 12-bit color display, Handheld PC operating system, English, German, French, & Japanese available. 2 Type II CF slots for wireless connection and extra memory. I do not have a pic on the web yet, but I can e-mail one if anyone wants to see it. A handheld version is available at http://www.iisvr.com/wireless.html. Stephen_glaser@iisvr.com | ||

HMD Interfacing for Handhelds: ============================== For iPAQ's there is at least 4 products that would provide the minimum vga rez for a HMD: 1) Expansion Pack - LifeView® FlyJacket i3800 2) CF - Colorgraphic Voyager VGA for Compact Flash 3) PC Card - Prolink PK201 4) CF - Margi Presenter-to-Go™ VGA Card I like the LifeView FlyJacket... the extra battery and included CF slot and Video IN and the inbuilt standard femail 15-pin VGA connector. Now, can I make it work under linux? *grin* Also... Reviews of the LifeView FlyJacket suggest that it's not capbable - in WinCE - of doing "full-motion video". Hmm. |
