Computer component maker Acer built a lightweight electric bike called the Acer ebii. Electrek reports: This lightweight 35 lb. (16 kg) e-bike features a number of gadgets and gizmos we have yet to spot in the industry, such as built-in AI designed to predictively control the transmission and make use of collision detection sensors for a safer ride. There's also proximity unlocking feature that the company says "automatically locks your bike when you leave and unlocks it again when you're nearby." My Gogoro electric scooter has a similar function, though that's a highway-capable vehicle.

Tracking capabilities are built into the ebii to help keep tabs on it 24/7. If the bike is ever stolen, it can be locked remotely and tracked using its built-in GPS locator. But don't think that you won't find typical bike parts here either, as the Acer ebii still features high-end components like a belt drive instead of a chain drive, 160mm hydraulic disc brakes, and 360-degree LED lighting. Airless tires are designed to remove the chance of flats, and a lefty-style fork does double duty as a conversation piece and a fancy weight saver.

There's also a 460 Wh electric bicycle battery that is said to offer a range of up to 68 miles (110 km) per charge. A top speed of 15 mph (25 km/h) and a 250W rear hub motor look to keep the bike within European and Asian power and speed limits. There's no hand throttle, which means riders will have to rely on pedal assist that is activated when the rider spins the pedals. It appears that there's some confusion about the 2.5-hour charger included with the bike, as some in the industry seem to think it can be used to charge phones and batteries as well. In fact, it's actually the e-bike's removable battery itself that can function as a portable power station to charge up your mobile devices. Pricing and availability are not yet available. But there is a launch video to build up excitement.

Lenovo is launching a new AR-and-VR system targeted at businesses. It's called ThinkReality, and from the looks and description of the device and platform, it looks like a competitor for Microsoft's HoloLens. Engadget reports: There are two parts to the new ThinkReality system -- the AR headset and a software platform. The ThinkReality A6 is a comfortable 380-gram headset with two fisheye cameras on the front, as well as depth sensors and a 13-megapixel RGB sensor. There's also microphones onboard for voice control, and the headset can also detect where you're gazing to optimize resolution or navigation. You'll also be able to interact with your virtual environments using an included 3DoF controller. Untethered, the A6 can last up to four hours with its 6,800mAh battery, and you can still use the device while it's plugged in and charging.

The headset connects to an SSD-sized compute box that contains a Snapdragon 845 CPU running an Android-based platform. There's also an Intel Movidius chips powering waveguide optics here, and each eye on the A6 offers a 40-degree diagonal field of view and 1080p resolution. By comparison, the HoloLens 2 uses a Snapdragon 850 CPU and packs two 2K MEMS displays. Microsoft also squeezes all the computing components into the headset rather than in a separate box like Lenovo does. While I'm not a fan of having to carry around an additional accessory to power a headset, this setup does make the ThinkReality A6 lighter, so it's a compromise I'm willing to make. You can wear the box on a belt clip or an armband, which should make it easy to move around when wearing this setup at work. Lenovo claims this is "one of the lightest fully featured AR headsets in its class," and during a brief trial with a non-working model, I certainly found the A6 lightweight.

ElectricSteve writes "When Robert Irving was diagnosed with Multiple Sclerosis, it was the catalyst for him and his childhood friend, Richard Little, to turn their engineering skills to the task of developing an exoskeleton that was a practical, standing-and-walking alternative to wheelchairs. The result is REX, an exoskeleton made of strong, lightweight materials that is designed to support and hold a person comfortably as he moves. Users strap themselves in to the robotic legs with a number of Velcro and buckled straps that fit around the legs, along with a belt around the waist. While most robotic exoskeletons we've looked at, such as the HAL, augment human motion, this is generally not an option for wheelchair-bound users, so REX is controlled using a joystick that sits at the wearer's waist level." The rig is expected to cost $150K when introduced later this year in New Zealand. Gizmag has an obnoxious timed popover subscription nag, so NoScript is indicated.

In Take 1 of this two-part series, I described some of the current technology in wearable computing as seen at ISWC 2000, this year's just-finished iteration of the International Symposium on Wearable Computers, from head-mounted displays to intelligent jackets. In this round, a little more speculation about where the future of wearability lies, with a peek in the door at some of the things being done in top university labs. What forces will shape the future of wearable computing? Hint: GeForce 2's are still hard to carry, and there's never enough power.

Once a year, would-be cyborgs and their creators congregate for a few days of catching up with each other and the state of the art at the International Symposium on Wearable Computers's conference, sponsored by the IEEE and corporate sponsors like Microsoft and Compaq. Ever-lighter and more colorful head-mounted displays, innovative input devices and boundary-stretching ideas on human/machine interaction conspire to attract strange looks from startled pedestrians or frank admiration from fellow participants. When ISWC2000 began Monday in Atlanta. it marked the fourth such gathering -- the event has been held in San Francisco, Pittsburgh, and Cambridge, Mass. ISWC is about equal parts trade show, academic conference, and family reunion for a visibly different kind of family. Since ALS had ended just one day before, I stayed in the Peachtree state an extra few days to check it out. Read on to see what I found.
