Differential keyboard - Samchillian
Overview
The Samchillian Tip Tip Tip Cheeepeeeee (or Samchillian, for short) is a type of electronic keyboard instrument invented by Leon Gruenbaum.
The Samchillian keyboard uses keys to trigger melodic intervals aka changes of pitch, rather than the traditional fixed pitches.
Because of the syntactical patterns also in music, as in many other progressions, indicating only the differences from previous allows to play the musical notes in the case, with minimal overhead and hence incredibly quickly.
The Samchillian can play very complex structures also.

Eyetracking Software Overview Summary
Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head.
Eye trackers are used in number of different areas in research and analysis, as well as in product design.
Examples Implementations and Systems
We highlight some different implementations of eye-tracking.
- LinkedIn Aideas Group - article The Engineer : Eye-tracking technology could benefit disabled children
- Eyetracking Web Usability (usability findings from eye tracker research)
Book about Nielsen Norman Group's eye tracking studies with links to articles presenting findings in more detail. - Eye Trackers - COGAIN: Communication by Gaze Interaction
A catalogue of currently available eye trackers, categorized into systems for assistive technology, research purposes etc.
PD Development Environments / Platforms
Some Public Domain development environments for eye-tracking software appliocation developnenet are:
- Open source gaze tracking and freeware eye tracking on COGAIN Wiki:
This list contains low-cost, free and open source eye tracking systems and research prototypes, and information that should help in building your own eye tracker. Some of them are targeted at people with disabilities (eye-control systems), some for more general eye tracking and research.

Trains & Rail travel Ramps - Transportation Accessibility Travel
In this blog entry we initially highlight two designs from newer trains where the access design for ramps for people dependent on wheelchairs and also ramp-operators railway-staff could be improved significantly.
The trains are:
Reference
- old rolling stock train types: Class 313, 315, and 317
New trains British Rail Class 379 "Electrostar"
The new Class 379 Electrostar initially introduced on the Stansted Express to and from London and Cambridge services, and recently also started to be used between London Liverpool Street, Cambridge and Kings Lynn.
Continuing on from the more considered holistic design seen in the British Rail Class 365 train design discussed below, the Class 379 "Electrostar" has had significant considerations with regard to accessibility in its' design.
However, the ramps fixing attachments to the train are protruding spikes (several inches long) perpendicular from the end of the ramp.
It seems an accident waiting to happen. Either to staff trying to help wheelchair dependent passengers on or off a train, or a wheelchair users, or anybody else on the platform at all.
Go to: top of page.
New British Rail Class 365 "Networker Express"
This was the new rolling stock of trains that was introduced by the then WAGN Train Operating Company on the Kings Cross to Cambridge line in 1994. This line include stations King's Cross to Cambridge and on to King's Lynn.
The Class 365 was also used on King's Cross to Peterborough and return lines.
The Class 365 was a significant improvement in accessibility, in that this had actually been though of positively during the design of it.
The Class 365 trains had wider iles in the carriage. Just wide enough for a wheelchair to pass if there was a 'must' situation. A carriage specifically for wheelchairs had also be designed and was on every train. It was the train carriage that had the toilet. The toilet had also been designed to allow access for wheelchairs.
The number of seats had been reduced in all carriages to allow more space a comfort for all passengers.
All these improvements were massive enhancement over what had been before.
The intent was outstanding and in our opinion should be hugely applauded.
Some details that probably could have been completed somewhat better, however, if a little more consideration and customer-r&d had been done.
The nearly more than twice as wide door opening, which was also a significant reason for reduced number of seats, also meant it was now very difficult for the fitter active wheelchair user to reach to the side of the doors as is a practical must if he or she was to get himself or herself in our out of the carriage.
I.e., by good intent the design had reduced abilities of a significant proportion of wheelchair users.
The other design feature of the Class 365 train was that the door opening now had a small step. The step was not deep enough for anybody to stand or step on, it was simply a halfway protruding lower extension that if considered from a sideways profile would give a quite nice gentler graduation of now two steps to push/pull a pram, a shopping cart, or a wheelchair up or down.
Again very admirable design intent.
The problem with it is that the extra (halfway) step, that is not deep enough to step or balance on, made the distance from the platform to the carriage floor that much further, that a shorter wheelbase wheelchair that is desirable by all wheelchair users as it makes the turning circle of the wheelchair smaller and therefore the chair more manoeuvrable, no longer could bridge the distance from the platform to the carriage floor.
I.e., again by good intent, the design had reduced abilities of an even greater proportion of wheelchair users.
Go to: top of page.
Old trains types Class 313, Class 315, Class 317
The more extreme wheelchair and fit sports wheelchair users could get themselves on and off the by an extreme backwheel balance and then pull themselves up into the train carrigage by pulling on the handles at the sides of the quite narrow doorway.
Once inside, however, the wheelchair user would have to stay in the intrance gangway, as the opening to the seated areas of the the train compartment was too narrow for a wheelchair to enter. (Nor was there any room for the wheelchair inside the carriage.)

Trains Rail Travel Transportation Accessibility Overview Summary
Overview Summary – Trains & Rail Travel Transportation – Accessibility
Train and rail travel is obviously a massive topic only from perspective of accessibility alone. We will not attempt to cover all on the blog, as that would be blinkered of the other many different resources there already are on this.
The blog will focus on train and rail travel accessibility, from perspective of personal recounts and observations of travellers, encouraging highlights of both bad and good experiences, and looking particularly at ways and suggestions for how things might be improved also from technological and equipment perspectives (both simple and more advanced).

UK Trains and Railways
In the UK the national trains system was separated in to a number of regional independent Train Operating Companies (TOCs) during the railway privatisation 1993/1994. Each TOC operates as an independent business unit under the collective National Rail brand. (More information is available at Wikikedia.)
The current TOC (Train Operating Companies) are listed below:
Find contact information, ticketing and fare options and be sure to checkout the onboard facilities. Contact information availble for each of the Train Operating Companies individually. Their contact details from the National Rail website at the below links.

Wheelchairs Toilet Commodes and Shower-chairs - also for Travel
Design Objective – Design Problem Statement
The design requirement 'problem statement' for the potty toilet commode product is simply:
a modular and versatile potty suitable for young children through to small adults.
The shower-chair requirement for wheelchair users for travel is similarly:
a foldable - and easily transportable - shower-chair, that is stable and affordable.
Shower-chair – also for Travel
For many wheelchair users a travel shower chair that folds up and is light is a must if wanting to travel.
Availability of well designed and reasonably priced options seems minimal.
Children's Potty Commodes
Disabled children potty commodes are distinct from travel shower chairs but a similar product sector and again lacking in reasonable designed or priced product options.
