There has been a big push for 3-D at movie theaters and on TV sets, so it was only a matter of time before digitally enhanced fisticuffs started popping out of smartphone screens, too.
The 3-D technology is the most boasted-about feature on HTC's new EVO 3D smartphone, which goes on sale Friday. You can watch 3-D movies and play 3-D games without putting on annoying glasses. You can shoot 3-D photos and videos, too.
The inclusion of 3-D is gimmicky and might make you feel nauseous, but it is creative at times and the EVO 3D is a fine smartphone overall. The phone costs $200 with a two-year service plan with Sprint Nextel Corp.
I wear glasses, so I was excited that I didn't need to put on another pair to try out the EVO 3D. The phone creates the appearance of depth using a technique called autostereoscopy. The screen has a layer that guides light so that the light from one pixel goes to the left eye and from the next to the right.
I got right to work watching a 3-D version of "The Green Hornet," which came with the phone. I was wowed by a fight scene where glass seemed to be flying out of the screen. A friend I handed the phone to even flinched when the shards blew past.
I also checked out some animated 3-D clips on YouTube. The scenes that looked best were, not surprisingly, those with people and objects in the foreground and background and with things moving right toward the camera.
Whether I was watching 3-D or 2-D videos, the phone's 4.3-inch touch screen was crisp and colors looked vivid.
That said, my brain wasn't thrilled about processing the 3-D images, so I couldn't stare at the display for long without feeling queasy.
It was also evident that I wouldn't really be able to share the dizzying experience with friends unless I handed them the phone. You need to tilt the EVO 3D in your hands until you find the viewing angle that is optimal for your eyes. That may not be an optimal angle for the person next to or behind you.
You can, however, involve buddies by letting them star in a 3-D movie or in photos that you shoot with the EVO 3D. The phone takes pictures or videos by recording overlapping images when its two 5-megapixel cameras are side by side. The camera lenses are positioned next to each other only when the phone is on its side, so you can only capture things in 3-D in "landscape" mode.
I couldn't manage to take any great shots, however. The images always seemed fuzzily misaligned, even with the inclusion of a feature for adjusting the alignment of the images.
I was more successful with the 3-D video camera, though I couldn't test whether objects really fly off the screen because my colleagues wouldn't hold the camera for me so I could throw things at them (even when I promised to lob only wads of paper at the lens).
I could see how the 3-D mode might come in handy for recording sporting events, especially if you're crazy enough to jump into the fray and fast enough to stay ahead of the action.
If you're not into flowers or people popping out of the screen, you can switch to 2-D mode by pressing a button on the side of the phone.
I also liked that the phone had a button dedicated to the camera, which I always find easier to take photos and videos with than a virtual touch-screen button.
The phone has a front-facing camera, too, for taking self-portraits or video chatting.
