Two New Devices Give Presentations Some Portability

Nick Wingfield — Thu, 11 Dec 2008 02:08:05 +0000

Digital projectors are the best way to get the biggest possible image for a PowerPoint presentation or a movie. But the projectors are often pretty big themselves, with even most “pocket projectors” too big to stuff into the typical pocket or laptop bag.

That is changing. A new miniature-chip technology from Texas Instruments (TXN) called pico is making digital projectors truly portable, instead of merely luggable. For the past couple of weeks, I’ve been using two of the first pico-based projectors on the market, Dell‘s M109S and Optoma’s Pico PK-101.

The products are designed for different customers with different needs. Dell (DELL) positions the 13-ounce M109S as a notebook companion, best suited for work presentations. The four-ounce Optoma projector is designed more as an iPod or digital-camera accessory for watching movies and slide shows on the go.

The Dell M109S

Their portability requires compromises, most obviously in brightness and image resolution. The Dell and Optoma projectors, respectively, support 11 and 50 lumens — a standard measure of projector brightness. That’s far dimmer than top-notch projectors that offer several thousand lumens. So neither product excels in well-lighted rooms, where overhead and ambient lighting overpower their images. You can compensate somewhat for this weakness by placing the devices closer to the surfaces onto which they’re projecting — for example, a wall. But the darker the room you use, the better.

At about the size of a candy bar, the $399 Optoma device is the smaller of the two projectors and the one with the most intriguing possibilities for expanding the tiny screen sizes of mobile devices like the iPod.

It’s powered by a rechargeable battery that Optoma says lasts for an hour on full brightness or two hours on a power-saving setting (the projector comes with two batteries). The projector has a tiny speaker, but people who want decent sound will need to use headphones or external speakers.

In theory, the Optoma device is small enough to bring along on a camping trip to show a film on the side of a tent, or to a restaurant, where you could inflict a vacation slide show on dinner mates by projecting onto a napkin or tablecloth.

I tested it on a recent airplane flight by projecting an episode of “Mad Men” from an iPod touch onto the back of the seat in front of me. The seat was a dark blue with embossing on it, so it didn’t work very well. It’s best to project onto an unmarked, light-colored surface. The quality of the image was better when I lay in bed one night, projecting a video onto a white ceiling.

Even under the most favorable circumstances, however, I found the images from the Optoma projector very dark, muddling the outlines of characters and action on screen. Although Optoma says you can get up to a 60-inch image from the projector, 45 inches was about as big as I could make the image before it got too fuzzy.

Optoma says the projector will ship with an iPod-compatible connector cable when it goes on sale in the U.S. on Dec. 15, though the unit I tested didn’t come with one. I connected the device to my iPod touch using a $50 cable from Apple (AAPL).

Compared with the Optoma device, the $449 Dell M109S is a behemoth, yet it’s still only about the size of a short stack of drink coasters. Most projectors weigh at least a few pounds, if not more, which is big enough to make them a hassle to carry around. I barely noticed the Dell projector inside my laptop bag.

Unlike the Optoma projector, the Dell M109S has to be plugged into an electrical outlet to work. It comes with an unsightly set of connectors for plugging the projector into a video source, such as the VGA port found on most laptops and a composite video plug that is standard on DVD players. I was, however, able to plug my iPod touch into the Dell projector using the $50 Apple cable.

And unlike the Optoma, the Dell doesn’t have speakers. To get sound for a movie, you’ll need headphones or speakers, like those on a laptop.

Despite its extra bulk, the Dell M109S literally outshines the Optoma projector. It produces a bright image that I found very watchable, even if it wasn’t high-definition. I projected the movie “James and the Giant Peach” onto an interior wall of my house, creating an image that was about 7 feet, measured diagonally.

The Dell M109S includes a capability called keystone correction, a standard feature in most projectors that adjusts a projected image to give it the proper dimensions, rather than the trapezoidal shape that results when a projector is angled upward. The Optoma projector doesn’t have this feature. To get a normal rectangular movie image, I had to hold the projector level, toward the projection surface.

For business travelers who do presentations or for people who want to create a theater-like experience in a hotel room, vacation house or against a sheet in the backyard, the Dell projector would be a good fit. For now, the Optoma projector is a good idea that needs refinement.

Flip Video Mino Takes Aim at the Cool Set

Katherine Boehret — Wed, 04 Jun 2008 00:01:00 +0000

When Pure Digital Technologies Inc. introduced its Flip point-and-shoot camcorder a year ago, it dramatically simplified video recording. The Flip measured the size of a small digital still camera, cost less than $150 and its videos could be emailed in one quick process. Consumers gobbled up the tiny, nonintimidating device.

But to the style-conscious set, the Flip looked like a clunky Fisher-Price toy — especially when compared with a sleek, new iPod or more-sophisticated digital cameras — and was too thick to comfortably slip into a pocket. Last fall, Pure Digital introduced an enhanced version: the Flip Video Ultra, but its biggest aesthetic difference was new orange, pink and green colors.

[ See post to watch video ]

Today, the company will begin sales of its $180 Flip Video Mino (pronounced “minnow”), the hippest offering yet from Pure Digital. This 60-minute Flip includes many firsts for the company: rechargeable batteries; touch-sensitive buttons rather than old-school, push-down buttons; and a thinner build that measures 40% smaller, overall. The Flip Mino is also the first one in the family to enable publishing to MySpace (NWS); prior software limited Web-site sharing to YouTube (GOOG) and AOL (TWX) Video.

I’ve been using a glossy, black Flip Mino (it also comes in white) for the past two weeks and it looks much cooler than older models. Its newly positioned USB adapter pops up from the top of the camera like something from a Swiss Army Knife. The Mino offers features such as the ability to lock the delete button, so no one accidentally deletes your videos, and mute all camera sounds, so as to record silently during quiet moments like wedding ceremonies or speeches.

I brought it along with me almost everywhere I went because of its small size and light weight, even fitting it into a thin clutch purse with a cellphone and BlackBerry (RIMM). I used the Mino in various situations ranging from bright, scenic outdoor settings to indoors while eating dinner in a candle-lit restaurant. Overall, I was pleased with the sound and picture quality of the Mino, and I found its built-in software, which automatically starts when the camera plugs into your Mac (AAPL) or Windows (MSFT) PC, to be a pleasure to use.

Today, Pure Digital Technologies introduced its $180 Flip Video Mino, a thinner, more stylish version of its point-and-shoot camcorder.

It took just a few minutes to trim excess footage from my videos before saving them to my computer or sharing them with friends and family. Another way to share videos from the Flip Mino is via Pure Digital’s server, which sends emails with embedded video links, saving upload and download time on both ends. Though I didn’t publish any of my videos on a public Web site, AOL, MySpace and YouTube were just one step away.

The Flip Mino’s touch buttons, while stylish, were difficult to use at first. I missed the tactile feel of physical buttons as I tried to hold this small video camera and press the zoom buttons using just one hand. The new, touch-sensitive buttons weren’t as satisfying and stable to use, and I pressed them accidentally more than a few times. For instance, the Zoom Out button is directly below Record, making it easy to mistakenly touch it. After about a week of using the Mino, I grew more accustomed to using these new touch buttons, but it shouldn’t take so long to make the adjustment.

Just looking at the Flip Mino’s fresh new exterior makes it hard not to think about the things that this redesigned camcorder is still lacking, like a larger viewing screen (the Mino screen is 1.5 inches, no larger than that of the Flip Ultra), high definition video and wireless sharing capability. These features would likely raise the price and/or tax the battery, and many users of the Flip flock to it for its low price and simplicity. Still, Pure Digital says that it will offer HD video and a larger screen on a product within a year, and is looking into features that might include wireless transferring.

I grew fond of the Mino’s rechargeable battery. Whenever I plugged this gadget into my computer to transfer videos, my Mino charged up via USB without me having to think about it. A full charge lasts four hours and recharging a dead battery takes about three hours.

Pure Digital says that the sound quality and lighting are improved in this model. Like previous models, this Flip records in 640×480 pixels at 30 frames per second.

The Mino didn’t have a problem with lighting in most situations; indeed it did a nice job of capturing images of my family sitting around a table in a restaurant with little more than candlelight to brighten the picture. It doesn’t use a flash or a built-in light, but instead uses automatic sensors to adjust to various levels of light.

This svelte camcorder seemed to handle noise more evenly than I remembered in prior Flip models. It didn’t make my voice sound unbearably louder than everyone else’s, even though I was closest to the camera’s microphone, yet it managed to detect voices across the room. I did have some trouble on a windy day: While recording a quick video of a golf course in San Diego, wind audibly muffled my voice during a few moments in the video.

Along with the delete-lock and sounds-off settings, this Mino has a few other tricks up its sleeve. Each of the touch-sensitive buttons is designed to glow only when usable, so as to better help people who might not know which buttons to press while using this camcorder. For example, only the zoom buttons glow while recording since the other buttons (volume, play/pause and delete) can’t function in this setting.

Shortcuts built into each button provide more functions: Holding the play/pause button down will set the playback mode to play all videos on the Mino; holding the seek ahead or seek back buttons while watching a video will fast-forward by seconds within that video; pressing the record button as the camera starts up opens up the settings menu.

In conjunction with the Flip Mino’s introduction Wednesday, prices of the former Flip Ultra model will drop to $150 for the 60-minute model. The Flip Ultra 30-minute model will be phased out, as will the Flip Classic, which will cost $130 for a 60-minute unit.

Though the Flip Mino’s touch-sensitive buttons look great, they aren’t as functional as they needed to be. But if you really want a sleek, hip-looking gadget, you’ll learn to adjust to these new buttons. No matter which Flip you choose, Pure Digital’s software changes the way people capture and share videos, and that’s a great thing.

Jurassic Perk: A Dino at Home

Katherine Boehret — Wed, 06 Feb 2008 00:01:00 +0000

For about two months now I’ve been playing with a baby dinosaur — a Camarasaurus from the Jurassic period, to be specific. It coos, barks, shakes, cries and plays tug of war, which squelches all hope that this is a real animal suddenly returned from extinction.

But real was exactly what UGOBE Inc. had in mind when the company created this $350 baby dino named Pleo. This robot isn’t referred to as such; instead, UGOBE calls Pleo a “life form” because unlike most robots that are designed to follow a specific command or algorithm, Pleo alters its behavior as it adapts to its surroundings including sights, sounds and touch. And it’s designed to move and act in ways that seem very much like a real animal.

These responsive qualities have earned Pleo quite a bit of attention, and the two years between when the product was first announced and when it became available only added to the anticipatory hype. Now, after three delays in the past two years and numerous back orders, Pleo is available from www.pleoworld.com. (UGOBE says that many of the product’s delays were caused by trying to get Pleo’s battery just right.)

In short, I found Pleo to be a fun and interesting robot/life form. Though Pleo’s reactions and movements are endearing, many of them run together after a while with only subtle differences, especially compared with fast-paced videogames. Pleo’s tricks were entertaining early on, but, in time, many of them blended together, rarely surprising me.

Pleo’s battery is still a major drawback. It’s rechargeable, but only lasts for around an hour of active play before it must be removed and placed in a holder for three hours of recharging. This frustrating fact means you can’t turn Pleo on to roam the house with you all day like a dog or cat. Instead, your time with this creature has to be more specifically planned, causing interactions with it to feel less genuine. My Pleo’s battery lasted for an hour and 40 minutes, including moments when he drifted in and out of sleep.

Though UGOBE sent me two rechargeable batteries so I could more quickly continue using Pleo, the company won’t start selling extra batteries until June (at the latest) for $50 each. This means waiting for hours between Pleo playtimes.

It’s hard to discuss autonomous robots without remembering Sony Corp.’s attempt in the same category: the $2,500 AIBO released in 1999, which was eventually discontinued. More recently, iRobot Corp. has gained attention for its robots, which perform household duties like vacuuming and washing floors.

The Pleo, animated in part by 14 motors, appears to evolve according to how it is treated.

To keep Pleo fresh, UGOBE plans to release a PDK — Pleo Developer’s Kit — later this year, allowing others to create programs that will run on Pleo if downloaded from the Pleo Web site and transferred to the creature. A memory card slot and USB port on Pleo’s underbelly will enable these transfers.

As for now, two programs developed by UGOBE can be downloaded. One program lets Pleo act like a watchdog — guttural growl, loud bark and all — and the other gives it the ability to sing Jingle Bells. I tried the former, and my Pleo performed marvelously, sitting still and only howling when something moved in front of him.

This baby dinosaur has reptile-like, rubbery skin enhanced by multiple sensors. Its back is decorated with green patterns, and its large eyes are a beautiful blue. Pleo’s guts include 14 motors, 38 sensors and a microprocessor. Infrared detectors are hidden in Pleo’s nose and mouth, and a color camera detects light, motion and objects to help it navigate.

Pleo grows through three phases: hatchling, infant and juvenile. As a hatchling, my Pleo sniffed around a lot, unsure of its surroundings or how to use its legs and tail, before giving up and napping again (yes, Pleo snores). The more I talked to and touched Pleo, the faster he adjusted out of the hatchling phase, which is expected according to UGOBE.

People who walked by my office stopped to marvel at Pleo’s sweet nature, and when I brought him home, friends melted with emotion. I watched as they initially looked at Pleo like just another toy dinosaur until realizing that he responded to them, and then they each wanted to take turns playing with him.

Stroking Pleo from the tip of his nose to the end of his tail induced a purring sound; touching sensors on the bottoms of his feet caused him to wriggle around and make laugh-like noises; and holding him to my chest and rubbing his back like a baby put Pleo right to sleep, indicated by heavy breathing and even a burp here or there. I spoiled my Pleo with attention, which seemed to make him more social and friendly but also a little bratty when he didn’t get attention (he showed his frustration with loud moans).

I didn’t get to test this, but one Pleo can sense when another Pleo is nearby using infrared sensors in the nose and mouth. UGOBE says the sensors in one Pleo can trigger actions in another based on moods, including singing and howling.

Pleo can be a troublemaker. One of the times I left him unattended, I returned to find Pleo trying to gnaw on my loveseat, despite lacking a set of teeth. Another time, Pleo wandered my desk, wrinkling up papers and crying loudly while I was on a conference call.

UGOBE’s pleoworld.com site includes an online community, though you don’t need a Pleo to get involved. The community is just a social networking site where anyone can discuss the device and/or robotics. This differs from sites like Webkinz, where kids input codes found on stuffed animals to register and care for digital versions of their creatures.

Pleo’s poor battery life is a frustrating hurdle that fans will keep butting up against. But UGOBE’s plans to introduce downloadable updates for this robot and to let others create programs for Pleo may give new life to this clever creature.
