Brain Computer Interface - A New Feature for Smart TV

by Mick 0 Comments

While still on the subject of head mounted displays, I recently noticed that NeuroSky announced a partnership with the Haier Group to integrate NeusroSkys brainwave detection technology into their latest 'Cloud Smart' TV, due for release later this year..

As neurons in the brain interact, for example  as a result of thoughts or changes in emotional states, they generate small electrical charges which can be measured using specialist EEG (ElectroEncephalogram) equipment. NeuroSky's mission is to make the technology available to a wider market outside of the laboratory, and they have produced the MindWave device for under $100.

Their technology can detect and convert electrical impulses generated from concentrated mental states into digital signals that can be used by electronic devices and ultimately, as suggested in this case, changing channels or adjusting the volume on a TV.

ASUS WAVI Xtion

by Mick 0 Comments

ASUS announced innovative new motion-sensing control technology at CeBIT 2011, the first ever for the PC. WAVI Xtion combines full HD wireless media streaming with a PC-based motion-sensing interface to bring an exciting new approach to home entertainment. High definition movies, games and photos stream smoothly to HDTV over 5GHz wireless with a 25m range. Full remote control of multimedia playback, games and other applications in living room comfort becomes possible through intuitive gesture input via the Xtion Portal interface.

The motion sensing technology comes from PrimeSense and is also used in the Kinect.

Developers are promised that the Xtion PRO development kit will be available soon and I'm still watching out for more details.

I wonder if it will it be ready before the official SDK for the Kinect on the PC is made available from Microsoft?

HP Pocket Whiteboard

by Mick

HP recently announced the HP Digital Learning Suite.

https://www.hp.com/hpinfo/newsroom/press/2011/110202a.html

One item mentioned, as a component of this suite, is the HP Pocket Whiteboard.

It consists of a receiver and wireless stylus and allows almost any flat surface to become a digital whiteboard (I'm not sure it will work on glass).

The receiver is connected to a PC using a USB cable and captures strokes and taps using the stylus which are recorded and can be processed by software.

It's scheduled to be available by the end of February 2011 - I haven't come across any pricing information yet.

It's Bananas

by Mick 0 Comments

We have Joysticks, Light Pens, Digital Pens, various types of Game Controllers, Keyboards, Mice, Touch Devices, Image Scanners, Barcode Readers, Smart Cards, Speech Control devices and now the Kinect.

But why can't you use anything as an input device?

To explore the concept further, I chose an item I found lying around in the kitchen and here are the results.

Does it fit on the desktop?

Flexibility

It has a number of different orientations that can be used perhaps the most common being horizontal.

or it can be held in a vertical orientation

I discovered that the horizontal orientation was the most comfortable and was also the best when held in 2 hands which provides greater stability when manipulating the device.

So the object itself is suitable, how do we turn it into a working device?

How to make it work

Bluetooth is not going to work and neither is a direct wired USB connection, however I found some software which enables you to track a brightly coloured object using a web-camera.

The software will track the longest axis of an object and this is used to determine the orientation. The center of the object is determined by intersecting an axis across the width of the object with the longer axis. The center point is used to calculate the position of the controller in the plane of the PC screen e.g. the position of the cursor when emulating a mouse.

This approach allows you to easily emulate a mouse using the object and you can simply rotate to the left to simulate a left-mouse click and rotate to the right to simulate a right-mouse button click.

Watch it in action driving the SolidWorks 3D CAD Modeling Application.

If you look carefully you will notice the tracking symbol superimposed by the software on the object.

This was created by the software as a virtual tracking symbol and is not something actually taped to the object!

Required Components

  • 1 Brightly Coloured Object
  • Web-Camera
  • CamSpace software
  • SolidWorks or other Windows Application
