We know, "back to school" isn't exactly a phrase that brings a smile to most students, but IOGEAR is hoping to get you a bit more jazzed up than usual about the fall semester with a new duo of products. Following the Digital Scribe, the firm has now unveiled a 4GB Flash Wallet Drive and 3-in-1 Wireless Phaser Presentation Mouse to presumably help you with your studies. The uber-thin wallet drive ($69.95) measures in at just 3-millimeters thick and ought to hold quite a few research papers, while the wireless mouse ($59.95) combines a laser pointer and track ball to aid you in making those presentations go as smoothly as possible. Both products should already be available at your campus store or nearby big box retailer.

No doubt we've seen some snazzy takes on mousing instruments, but when Popular Science dubs your twist on the critter we couldn't do without an Invention of the Year, you've accomplished something. A team of WPI undergraduate students were able to win such an honor by crafting the MagicMouse, a "three-dimensional computer mouse" that allows users to "control and manipulate items on a computer screen just by pointing at the monitor." While we've seen similar ideas for helping disabled individuals interface with a computer, this wee iteration actually fits around one's finger and "uses an array of receivers to track the motion of a tiny ultrasonic transmitter." The cursor is moved by waving one's hand back and forth, while moving closer and backing away enables zooming functions to be utilized, which should make handling those CAD drawings a good bit easier. Perhaps most notable, however, is the relatively low cost of assembly, as the entire contraption (rechargeable Li-ion and all) cost just $155, and we're sure you know how far that could fall if a bulk buying manufacturer brought it to commercialization. A few more pictures after the jump.

We've seen sensor-laden, iPod-friendly, and electroluminescent garb in years past, but a crafty design student over at Cornell University wasn't satisfied with stopping there. Olivia Ong is hoping to get her career in fashion off to a very safe start, as her functional clothing lines include "a garment that can prevent colds and flu and never needs washing," and if that wasn't fresh enough, she's also conjured up another that "destroys harmful gases and protects the wearer from smog and air pollution." The prototype Glitterati garb was showcased at the school's Design League fashion show, and both articles contained "cotton fabrics coated with nanoparticles" that give them the unique qualities. No word on whether or not we can expect such protective (albeit stylish) threads to hit the strip anytime soon, but considering that "one square yard of nano-treated cotton would run you about $10,000," we doubt us common folk would be selling off assets to take it home anyway.

We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.

While we English speaking folk may prefer our pocket translators to start in English and convert to some other foreign tongue, Casio's latest rendition helps those fluent in Japanese order tickets to the Space Needle, haggle at the Chevrolet dealership, and of course, pick up the correct ingredients for warm apple pie. Aimed at middle / high school students, the XD-SW4800 lineup of handheld dictionaries reportedly house the denotation and correct pronunciation for over "85,000 languages," which ironically enough, probably translates to "85,000 words" when not read through a broken translator. Nevertheless, these handy gizmos come in a variety of colors, and aside from supporting keyboard input, it can recognize stylus-written characters and toss back definitions while pronouncing the word to you via headphones. If America isn't your final destination, it also comes with five other major languages on CD that can be loaded on the 50MB of internal space or on your SD card if necessary, and while these things won't last forever, the approximate 60 to 130 hours of battery life should be more than enough to get you acclimated. So while you're waiting for your passport to show up, make sure you pick up Casio's latest travel necessity -- if you can manage the admittedly steep ¥47,250 ($394) to ¥52,500 ($437) price points, that is.

Let's face it, not all of us will have the luxury of attending a school where we get to construct massive LEGO machines or learn how to become savvy in SMS, but a developing technology that tracks student emotions could help tutors and distance instructors alike in keeping kids focused while learning. Co-developed by Essex University's Vic Callaghan and Shanghai Jiao Tong University's Liping Shen, the emotion-tracking tutoring software can analyze physical signs to keep track of a student's attention span, their level of understanding, and even the amount of stress a certain lesson produces. Aimed to help tutors become more effective and to add another layer of "personal" to distance-based education courses, the software would receive information about a student's "heart rate, blood pressure and changes in electrical resistance caused by perspiration" via a sensor-laden, Bluetooth-enabled ring worn on one's finger. The information can then be assessed to determine a student's interest level and frustration level, but a decibel meter to measure snoring isn't likely to be included. If all goes as planned, the team intends on testing the system out in "real learning scenarios in China" to further tweak their creation, so it won't be too long now before an interest-tracking ring will become as necessary as pencil and paper a stylus and a tablet PC come class time.

In yet another sign that Luddism is alive and well in academia (remember Lakehead University's silly WiFi ban?), the Associated Press has picked up on a disturbing "trend" of professors banning laptops in their classrooms. Unlike the WiFi brouhaha, which revolved around fears that the wireless signals might be dangerous, keeping laptops out of the lecture hall is seen as a way of forcing students to pay attention. The AP article cites several law school professors who have enacted the ban, including one whose inspiration came while serving as an expert witness in a trial, when he realized the court stenographer wasn't absorbing any of the content that he/she was transcribing. If you ask us, not only does this policy fail to address the root of a problem -- hey Prof, try making your classes more interesting if you want people to pay attention -- but considering what students are paying for a higher education these days, they should be allowed to lug a mainframe and three monitors to class if that's how they like to get their learnin' done.
