There are many gestural interfaces under development, but our fingers remain one of the most useful tools we have. Fujitsu's FingerLink lets your fingers control a scanner and projector for printed information, acting as a bridge between digital and analog tech.

The prototype uses off-the-shelf cameras and projectors. Fujitsu's image-processing software links the two.

It can accurately detect where your fingers are as you touch or swipe any printed matter, letting you copy text or images and project them elsewhere. The size of projected images can similarly be adjusted with a fingertip. … Read more

In home networking, the fastest way -- in terms of data speed -- to connect devices together is via network cables. However, running cables properly, which involves making networking ports and connector heads, is no easy task. This is part of the reason the wireless network (Wi-Fi) has become so popular. But chances are, there's a spot in your home that the Wi-Fi signal can't reach, because of distance or thick walls. This is when a power-line connection can be a useful alternative.

Power-line adapters basically turn the electrical wiring of a home into network cables for a computer network. You need at least two power-line adapters to form the first power-line connection. The first adapter is connected to the router and the second to the Ethernet-ready device at the far end. There are some routers on the market, such as the D-Link DHP-1320, that have built-in support for power-line connectivity, meaning you can skip the first adapter. After the first connection, you just need one more adapter to add another Ethernet-ready device to the home network.

Apart from the ability to bridge the network through thick walls, power-line connections are also a lot more stable than Wi-Fi signal and have as low latency and a regular Ethernet wired connections.

Currently there are two main standards for power-line networking, HomePlug AV and Powerline AV 500. They offer speed caps of 200Mbps and 500Mbps, respectively. The following is the list of top five power-line adapters on the market. This list is sorted by the review date, starting with the most recently reviewed. It will be updated as more devices are reviewed.… Read more

Not satisfied with just smartphones, MP3 players, and computers anymore, the rumor mill has now tacked on "smartwatch" to the list of potential hot items that Apple will develop and manufacture. Dubbed "the iWatch," chatter about Apple producing this sort of wearable tech is timely, considering that smartwatches seem to be on the mind of a number of other companies as well.

From bendable glass to an OLED screen, we gather all the dish on Apple's iWatch. Please note that we'll continue to update this roundup periodically and feel free to let us know … Read more

One of the biggest bugbears of smartphones is just how much juice they drain -- and how long they take to recharge. Batteries are also the reason many devices can't be smaller; after all, the batteries have to fit somewhere (although, given the burgeoning phablet market, that's not exactly a huge problem).

Scientists have made several recent attempts to build a better lithium ion battery. In the latest push, a team of researchers led by mechanical science and engineering professor William P. King at the University of Illinois in Urbana-Champaign has developed a new type of lithium ion battery that's just a fraction of the size of the batteries we use now -- and that can out-power the best supercapacitors. … Read more

If you long for high-tech eyewear but can't afford, or wait, for Google Glass, these Japanese glasses let you record in HD for less than $100.

Mitamanma Megane from Japan's Thanko hide the camera in the frame and only cost 8,890 yen ($91). That's cheaper than similar products like Pivothead video glasses, which go for around $300. … Read more

If all you envisioned developing by being an early recipient of Google Glass Explorer Edition was a quick resale profit, think again: Google has rules against reselling the wearable tech without its permission.

As the Web giant began shipping the high-tech specs this week, it also unveiled a host of developer preview documentation, specs, and rules about what developers could and couldn't do. One of those things, apparently, is reselling or even loaning the $1,500 device to someone else. Developers who do risk having their prized specs deactivated. … Read more
