Place to Play Research - Thin Film Display

You've finished working on your computer and you're ready to call it a day. Instead of logging off and folding the screen down over a laptop keyboard, imagine rolling up the computer screen and stashing it in your bag. Roll-up computer screens and other flexible light-emitting displays that conform to almost any shape or surface may one day be realities thanks to a team of scientists at Pacific Northwest National Laboratory.

The researchers have developed two key technologies--the Flexible Glass^TM engineered substrate that provides a flexible surface on which to build a display and the Barix^TM thin film coating that protects a display from harmful air and moisture. These technologies offer the display industry the design flexibility of plastic and the barrier protection of glass.

Because it prevents moisture vapor or air from passing through, glass--durable but rigid--has been the substrate used in both traditional liquid crystal displays (LCDs), such as cell phones and digital watches, and next- generation displays such as organic light-emitting diodes (OLEDs), which offer wider viewing angles, quicker response times and more ruggedness.

One challenge to manufacturing thin, flexible, and lightweight OLEDs was finding a way to make a flexible surface, such as plastic, also impermeable to air and moisture vapor, which quickly destroy an OLED display. The Barix^TM coating provides this protection. It also enables the manufacture of thinner displays with fewer potential failures at seams and joints by eliminating the bulky packaging required when using a glass substrate.

The Barix^TM coating is made of extremely thin layers of transparent ceramic barrier material deposited with alternating thin polymer (plastic) layers. The layering is repeated until the desired resistance to water vapor and oxygen permeability is achieved. The nanoscale inorganic layers (of less than 50 nanometers) sandwiched between the polymer layers (of less than one micron) produce composite structures that are flexible enough to be rolled yet still prevent air and moisture vapor from passing through. The Barix^TM coating is typically less than two microns thick. A human hair, on average, is 100 microns thick.

The Flexible Glass^TM engineered substrate is a transparent, flexible plastic sheet that blocks air and moisture but allows light to be transmitted, making it extremely useful in manufacturing sensitive organic electronic devices. Vacuum deposition techniques are used to deposit thin-film layers of nanoscale organic and inorganic materials in multi-layer stacks directly onto a substrate such as polyester film. Each stack is typically less than two microns thick. Display manufacturers can use the Flexible Glass^TM product as the substrate on which to build either OLED or plastic LCD displays. After the device is fabricated on the barrier substrate it can be hermetically sealed using Barix^TMencapsulation or another sheet of Flexible Glass^TM barrier material.

Both Flexible Glass^TM and Barix^TM technologies have been licensed to the Battelle spin-off company, Vitex Systems Incorporated, for commercialization.

Place to Play Research - Reverse Parking Sensors

Reverse Parking Sensors

Reverse Parking Sensors (also known as reverse parking sensors, reverse parking systems, and reverse backing systems) are a technology that allows the driver of a car, truck, van or commercial vehicle to be alerted to nearby objects in their path.

While there are variants in the design and feaures of these systems the basic design puts sensors in the car bumper or on brackets. These sensors send ultrasonic waves (40,000 times/second) that detect obstacles behind the vehicle. A controller installed inside the vehicle then receives the signal from the sensors and transmits it to a speaker that emits a tone, or to a combination speaker and display unit.

Place to Play Research - Video Tracking

Video tracking is the process of locating a moving object (or several ones) in time using a camera. An algorithm analyses the video frames and outputs the location of moving targets within the video frame.

The main difficulty in video tracking is to associate target locations in consecutive video frames, especially when the objects are moving fast relative to the frame rate. Here, video tracking systems usually employ a motion model which describes how the image of the target might change for different possible motions of the object to track.

Examples of simple motion models are:

• to track planar objects, the motion model is a 2D transformation (affine transformation or homography) of an image of the object (e.g. the initial frame)
• when the target is a rigid 3D object, the motion model defines its aspect depending on its 3D position and orientation
• for video compression, key frames are divided into macroblocks. The motion model is a disruption of a key frame, where each macroblock is translated by a motion vector given by the motion parameters
• the image of deformable objects can be covered with a mesh, the motion of the object is defined by the position of the nodes of the mesh.

Common Algorithms

The role of the tracking algorithm is to analyse the video frames in order to estimate the motion parameters. These parameters characterize the location of the target.

There are two major components of a visual tracking system; Target Representation and Localization and Filtering and Data Association.

Target Representation and Localization is mostly a bottom-up process. Typically the computational complexity for these algorithms is low. The following are some common Target Representation and Localization algorithms:

• Blob tracking: Segmentation of object interior (for example blob detection, block-based correlation or optical flow)
• Kernel-based tracking (Mean-shift tracking): An iterative localization procedure based on the maximization of a similarity measure (Bhattacharyya coefficient).
• Contour tracking: Detection of object boundary (e.g. active contours or Condensation algorithm)
• Visual feature matching

Filtering and Data Association is mostly a top-down process, which involves incorporating prior information about the scene or object, dealing with object dynamics, and evaluation of different hypotheses. The computational complexity for these algorithms is usually much higher. The following are some common Filtering and Data Association algorithms:

• Kalman filter: An optimal recursive bayesian filter for linear functions and gaussian noise.
  
• Particle filter: Useful for sampling the underlying state-space distribution of non-linear and non-gaussian processes.

Place to Play Research - Virtual Reality Goggles

Technology has brought virtual worlds into our computers for many years. Soon, vr will be in our living rooms.

The underground effort that has been an experimental fantasy for decades is becoming more mainstream. VRGs are headed to your game system!

VRGs or VR glasses (also known as Virtual Reality goggles) takes home entertainment and gaming to the next level.

The 3D simulated world once embedded on your computer monitor becomes a living world that consumes you instead. 3D graphic virtual reality is a reality.

Virtual reality glasses have improved in quality; become lighter and cheaper over the past decade as virtual reality technology and software also has advanced.

Wireless options allow you to roam the room with your headset. Almost all units plug into computers, DVDs and TVs.

The option for a Stereo 3D input is now available with Apple's latest in the line of Intel Xenon driven processors.

Sony Glasstron

There's no denying that a big screen provides the ultimate in viewing. Problem is, a big screen keeps you pretty much anchored to your living room or den. Fortunately, Sony has developed an extraordinary solution.

The Glasstron Audio/Video/PC Headset is Sony's newest portable big screen experience. This personal video theatre projects a 52" virtual image of your program inside lightweight, comfortable and futuristic-looking glasses.

You simply slip on Glasstron, connect to a video source or a PC, and you're ready for an eye-opening view of your favourite programming, complete with high-fidelity stereo sound.

Sony's Glasstron Audio/Video/PC Headset is so lightweight and compact you can take it just about anywhere. Whether you're relaxing on the couch, enjoying the great outdoors, or flying cross-country, Glasstron is designed to go to great lengths to enhance your viewing pleasure.

The same technology could be used for my system.

Place to Play Research - Laser Quest

Laser Quest

What is Laser Quest?

Laser Quest is the world's best known and most exciting brand of Laser Tag game. There are centre’s all over the UK. Whether you're 6 or 66 you'll love the adrenaline pumping exhilaration of stalking your opponents and unleashing a volley of laser fire in the battle-zone of the 21st century.

Playtime

To play Laser Quest you enter a fantasy world where you compete in a game of electronic tag. Each player is equipped with 'state of the art' laser tag equipment and plays the game in a uniquely styled labyrinth, which features custom built scenery, ramps, catwalks, lighting effects, swirling fog and futuristic music.

Points are scored when you successfully zap your opponent on one of the many sensors located on the pack and gun. But beware, if you are zapped you lose points and get knocked out of the game for a few seconds.

Using the Laser Quest software platform limitless game variations can be created from simple solo and team games to more complex advanced team games, sentinel games and base station games.

Place to Play Idea

My original idea was the safety system thing for a motorbike but it was decided that it didn’t really have a play factor. I thought about how this could be changed to become more playful. I came up with the following idea: -

The Idea

My idea is a product that you wear and interact with. To decide a name for my product, I wrote down lots of ideas and asked everyone in the lecture room to vote for their favourite. The winning name was ‘V-Tag’.

It’s a Virtual Reality system, which can change your environment and also lock onto other people with another V-Tag Pack on. The idea is to chase others down and shoot them but when you get shot, you get a small electric shock (this can be turned off though). You change the difficulty by making the environment system thicker so it’s harder to get to them but easier to hide. You can also make it so you have to lock onto the other players before you can shoot them. You could also change the settings on it or even have environment cartridges. There are cameras on the helmet that registers you environment and if you had say a ‘Jungle Cartridge’ in it then if you were playing in a playground and it would change it to look like a jungle. Music and sound effects can also be played to make it feel more real and exhilarating. This is not just for children, adults would love it too so you can interact with your children more and in the fresh air!

V-Tag is basically a virtual reality version of ‘Tag’.

The Materials

Like the game centre company, Laser Quest, you have jackets with sensors built in but you also have a helmet. The helmet has a Virtual Reality Display similar to the new Sony Glasstron. This enables you to see the world differently with the Environment changing software.

You also have a gun, which again is similar to the Laser Quest guns but lighter and smaller. You could even buy accessories sets, which could enable you to attach it to a bike so you can play ‘V-Tag’ on your bikes. A warning should be put on though saying that if using ‘V-Tag’ it MUST be played well away from roads or other vehicle operated places such as car parks.
