Creating Ripples

When innovation meets passion great things happen

Pre-launch announcement

One of the most revolutionary and innovative advances in technology for the blind and visually impaired is launching soon.

Immediate, life changing benefits

Ripple’s world first technology will radically improve peoples’ lives, by enabling the blind and visually impaired to move around indoors and out with greater mobility, confidence and independence.

Ripple merges cutting edge technology with beautiful design, meaning it is light, simple to use and looks great.

So how does Ripple work?

As inventors of Ripple we were determined to create a solution that would improve the quality of life for people who are blind or visually impaired. While people are at the heart of Ripple, it is the technology that enables us to deliver something truly life changing.

1

Ripple’s innovative camera uses Time of Flight (ToF) technology to create a digital 3D map (depth map) of the scene in front of the user.

The camera creates a 3D map by illuminating the scene with pulses of near-infrared light and then measures the time it takes for the light to reflect from the target back to the sensor.

This allows the distance to be calculated for each pixel by using the known speed of light.

2

Ripple then uses intelligent algorithms to extract useful information about the scene, such as identifying stairs, objects, low hanging branches, or sudden drop-offs and rises.

This information is transmitted instantly to a wireless wrist band, which uses vibrations (haptic feedback), or a optional Bluetooth headset/smart phone, to alert the user about potential hazards.

3

The wrist band conveys the information through vibrating pulses where the duration and intensity is controlled and the distances can be interpreted by the user.

Ripple is a technological leap for people who are blind or have impaired vision.

We are incredibly excited to introduce Ripple to the world and would love to hear from you at enquiries@ripplevision.me

Product development updates

31 May 2017
We are now getting into the testing stage. We alter such things as the haptic information transmitted through the wrist band, which enables us a better understanding of the proximity to objects.

The latest images show the Ripple Time of Flight unit (with the facing removed), and the Bluetooth haptic wrist band. We also see the device in action, showing road curbing and objects easily detected in brilliant sunlight, as well as head height objects.

23 December 2016
30 * camera boards, 30 * wristband boards, 30 * proximity boards and 30 * DART boards delivered.

Dual charger 30 PCBAs: assembled Dec 16. Testing starting on Jan 4 2017, then ready for Pilot Run.

30 sets of plastic parts available in early February 2017.

3 October 2016
Each Ripple Time of Flight image has three frames: raw depth map on the left, filtered depth map in the middle, then detected edges on the right. The nearest point of the detected edges is what will trigger a hazard warning.

These latest images show significant information and were taken in high ambient sunlight. They prove that the image filters recognise the correct outline for hazards on and above the ground. In this sequence, software engineer Grant used high laser power for a very short exposure with a high confidence requirement. Using a high confidence requirement means much less noise and less processing time, which helps in achieving a higher frame rate. As you can see, using Ripple in bright sunlight shows large areas of low confidence, but the important objects show up and the edges are detected as they should be.

This week, the final components have been ordered for the 30 unit pilot run.

21 July 2016
We are analysing data out of the chip and are on schedule to start outside ambient light tests in two weeks.

3 June 2016
The Printed Circuit Board (PCBA) is now being tested.

6 April 2016
Illumination board is complete and the software
documentation is being written.
