Keepvid.com is a website you can use to download videos from Youtube.

It is really easy to use, just paste the link into the URL bar and press download. You will then see your video with a variety of formats. In order to edit your video on IMovie (Mac) or Windows Movie Player (Windows) it is best to choose the MP4 format.

If you do not already have Java installed you will need to install it before you can download videos. There is a link which you can follow to do this.

Conversations between people include a lot more than just words. All sorts of visual and aural cues indicate each party’s state of mind and make for a productive interaction.

But a furrowed brow, a gesticulating hand, and a beaming smile are all lost on computers. Now, researchers at MIT and Tufts are experimenting with a way for computers to gain a little insight into our inner world.

Their system, called Brainput, is designed to recognize when a person’s workload is excessive and then automatically modify a computer interface to make it easier. The researchers used a lightweight, portable brain monitoring technology, called functional near-infrared spectroscopy (fNIRS), that determines when a person is multitasking. Analysis of the brain scan data was then fed into a system that adjusted the user’s workload at those times. A computing system with Brainput could, in other words, learn to give you a break.

Gesture Control System Uses Sound Alone

When you learned about the Doppler Effect in high school physics class—the wave frequency shift that occurs when the source of the wave is moving, easily illustrated by a passing ambulance—you probably didn’t envision it helping control your computer one day.

But that’s exactly what a group of researchers are doing at Microsoft Research, the software giant’s Redmond, Washington-based lab. Gesture control is becoming increasingly common and is even built into some TVs. While other motion-sensing technologies such as Microsoft’s own Kinect device use cameras to sense and interpret movement and gestures, SoundWave does this using only sound—thanks to the Doppler Effect, some clever software, and the built-in speakers and microphone on a laptop.

Inspired by reel-to-reel tape machines, microfilm, cine-film projectors and arcade games, Chronotape is a tangible timeline for family history research designed by Peter Bennett and developed as part of the PATINA project, within the Bristol Interaction & Graphics group. The device includes a number of different functions: ADD PERSON: place a person icon on the tape to mark an event (birth, death, marriage etc), WRITE NOTE: write directly onto the chronotape using pen/pencil, TYPE NOTE: type a note onto the tape, and PHOTO: snap a photo note of the your research materials or old photos.
