Workshop Leaders: Petr Cervenka, Lukas Masilko, Ondrej Necas
Country: Czech Republic
Duration: 3 hours (1 session)
Target group: blind students (maximally 8)
- Short introduction of technologies for preparing tactile graphics including demonstrations
- Demonstration of basic mathematical functions and their shapes
- Determination of functions from the tactile graphs
The main goal of the workshop is to introduce blind participants with methods how to perceive the information offered in tactile line graphs of mathematical functions.
The authors of the workshop start with several demonstrations of tactile graphics produced by different technologies so the blind participants can be aware of pros and cons of these specific approaches.
Then they focus on offering a list of basic mathematical functions with one parameter and their graph representation. The participants will be introduced with the curves of the functions such as linear, quadratic, rational, trigonometric, exponential and logarithmic.
Finally, they receive several pages of unknown curves in a tactile form and they shall try to determine which mathematical functions are represented by these graphs. It won’t be so difficult because of the slight modification of well-known basic functions (an argument’s change, adding or multiplying constants, etc.).
The workshops of Summer University were recorded. After editing you now can listen the records and read a transcript of the workshop. For better higher accessibility we have prepared the records in an hybrid version synchronized with the transcript. if you want to learn more about the player visit http://www.teiresias.muni.cz/hk3.
