We have a host of products that we are working on in different stages.

Our immediate offering is  Roulette  –  a drawing tool that creates a positive impression on most types of paper.  It is an affordable option to the textured plastic or mylar film currently used by the visually impaired to make  tactile drawings .

Patent 409199  granted on 18Oct2022

Useful for drawing freehand lines as well as drawing geometric shapes.  Roulette needs the drawing paper sheet to be placed on a silicone or neoprene rubber sheet.    https://www.youtube.com/watch?v=K3TmRjKIp78

While a drawing board with at least one clip to keep the paper fastened in place is desirable,  Roulette does not cause the paper to shift while using it.  So you will be able to use Roulette with just a rubber sheet if a rubber topped drawing  board is not available.  Roulette will not work if the paper is placed on a hard surface.

And now we introduce a complete set of tactile geometry drawing tools.  Touchétech Labs introduces a completely new set of tools called ‘Bisectors’ that are used to bisect lines and angles. Bisecting lines and angles are an integral part of learning geometry.  The difficulties a visually impaired person would have in finding points of intersection of construction arcs has always been a problem when trying to learn geometric principles.  This problem has been dealt with as now what was once a huge problem has become one of the least complex matters in  tactile geometry.

There are a lot of videos on my personal YOUTUBE channel @pgdsouza with interesting stuff I have worked on.

 

The following products are in the pipeline:

• Hexis – An E-Reader Braille display that we have produced in collaboration with Vembi Technologies and Vision Empower Trust.
• Braille Cell Modules and Mechanically Programmable Braille Cells .   Patent 400406 granted on 14Jan2020.
• Tactile Books for the sighted and visually impaired.  We should have something to display soon!
• Touché Type –  a Low cost Brailler.  This is on the back burner for the moment – but hopefully we will get time to breathe life into this soon!

 

Touché– Refreshable Braille Display (RBD)    An affordable version of this is being produced by VEMBI Technologies

using our Braille Cells.

This device is a result of over 8 years of intense work and dedication of a host of people. This device will revolutionize the way literacy is looked at for the visually impaired. Some of the salient features of this device are; low cost, high reliability, easily serviceable, multiple means of connectivity, user-centric.  Touché was developed as a product with the help and collaboration of Sapient Razorfish at their Kepler Lab.     www.touche.world

 

 

These individual Braille Cell Modules are designed to be used in instances where small programmable displays are needed.  They can be used to provide tactile feedback in items like rotary switches, temperature indicators,  Lift floor indication systems and even in toys and educational tools.

Patent 400406 granted on 14Jan2020.

 

 

 

These are our standard twin cell modules that we use in our devices and also what we supply to other Braille Device Manufacturers.  They essentialy comprise a twin Braille cell module with a controller PCB sandwitched between them. The Braille cell size and dot specifications are compatible with international Braille cell specifications. Each twin cell module comprises a pair of 8 Dot Braille cells. The boards can be cascaded to form Braille  lines of any length.  Patent  431129  granted on 04 May2023.

 

Touché Plus- Refreshable Braille Display with integrated Braille keyboard (note taker).   A work in progress…

This advanced version of the Touché refreshable Braille display will have an input device in the form of a Braille keyboard that will allow the user to input data and store data. This device will be an IO device which is pretty much a fully functional computer for the visually impaired.

 

Tiffy Template

A simple low cost invention that has ensured financial independence and freedom from fraud for the visually impaired. This template has been crowd funded on Fueladream with the aim of distributing it to over 2 million blind people in India. This was available free to any blind person in India.

UPDATE :    The Tiffy Template was discontinued post demonitisation.  It is not compatible with the newly minted currency issued by the Government of India.

 

Tactile Books for the visually impaired and sighted.     Update:  These are back in focus for production soon.

  A sample page from a tactile book designed to be used by the sighted and visually impaired alike.

Children derive great fun out of story books, we have produced a couple of very interesting characters which will enthrall children with their amusing adventures. Also, these books are printed using technology which will make them equally enjoyable and accessible to visually impaired and sighted students alike.  All illustrations have tactile features and texture variations that can be felt by the visually impaired.  Not visible, but present in the illustration,  is   Braille text.

 

 

Touché Type – Low cost Brailler

We are working on a low cost Brailler which will make personalised typing  out notes and books far more affordable and easier for the visually impaired.  The Perkins Brailler has been around for over half a century and is probably the heaviest and most cumbersome device a  Braille user can possess.  It is also prohibitively expensive. We aim to substitute this device with a sleek, low cost, lightweight replacement.  We will share further details at the earliest.

On the back burner – but will be revived as soon as time and circumstances demand.
