Cognitive Science of Tactile Graphics

In this research project, we examine the cognitive processes involved in the perception of tactile graphics and develop new designs to improve their utility and effectiveness.

We are devising novel experimental techniques to record and interpret readers’ strategies as they interact with tactile diagrams. We will use that knowledge, alongside our previous work on the design of diagrams for challenging educational topics, to create tactile graphics that better support comprehension, reasoning and learning.

If you are blind or visually impaired and would like to contribute to this project, please don't hesitate to get in touch with us by writing an e-mail to tactilegraphics@sussex.ac.uk.

The RM Phillips Research Network is going to run a showcase event on Tuesday 27 February 2018, 17:00 – 19:00, at the Brighthelm Centre in North Road, Brighton, BN1 1YD.

There will be a series of short talks by research teams from the 5X社区视频, as well as demos and networking opportunities. The event is suitable for anybody with a personal or professional interest in the topic, and also for members of the general public who are merely curious to learn more.
If you would like to attend, just register through the link below. Admission is free, and some food and drink will be provided.

 The tactile graphics project is featuring in tomorrow's opening event of the newly formed Creative Technology research group. On the day, we are going to present some of our tactile designs and run a series of interactive demos. Peter Cheng will also give a talk about how Cognitive Science can inspire new creative technology.

The event takes place on Sussex 5X社区视频 campus at SPACE, Bramber House, Tuesday 26 April from 4pm

 We are very excited to announce that Dr Grecia Garcia-Garcia has recently joined our team. Grecia will be involved in the design, setup and conduction of experiments using our amazing GrapaTouch tablet software. She will also perform data analysis tasks and generally support the evaluation of the GrapaToo software suite.

Today we held the fourth tactile graphics workshop in the CALPS lab. There has been some amazing progress on tackling the problem of tracking the identity of individual fingers in a scene. The image below shows a video still of the tracking software that was developed by Graeme Jones and Andreas Hoppe of Kingston 5X社区视频. This software performs its tasks based on an anatomical model of the human hand, and then visualises the results in a graphical overlay put on top of the RGB video of an experiment.

 

 Finger Tracking Software Output

GrapaTouch, our main data collection software for the project, has been completed. It constitutes the third addition to a successful series of data elicitation and protocol analysis tools developed by Ronald Grau (the other two, SKeyLog and SMouseLog, have been around for a while but will soon be improved and re-branded as GrapaMouse and GrapaKey). The new software is based on the Android operating system and will be used to capture touch and movement data in our upcoming experiments.
Development activitities will now intensify for GrapaToo, a universal graphical protocol analysis toolkit that will integrate various types of data and provide a range of tools for their exploration.

Ron Grau has conducted the third workshop on hand motion recognition using imaging techniques. Prof Graeme Jones and Dr Andreas Hoppe from Kingston 5X社区视频 London presented their updated software prototypes and a series of mini-experiments was carried out to gather data for testing. In the next step, the different data collection methods will be aligned such that the image processing algorithms can be augmented by feeding in the touch data collected with our tactile graphics tablet.
