Start creating your Technology Task. The requirements will be available in the complete task document under the information and resources tab for your chosen STEMIE theme. 

Brainstorm ideas for how you could make your device. You can use the engineering design process to prototype and evaluate your design. 

More information about the engineering design process can be found here https://www.sciencebuddies.org/science-fair-projects/engineering-design-process/engineering-design-process-steps

Sample projects to give you some ideas for interactive displays can be found in the Creating interactive displays using Duinotech kits section of the student workshop. 

Remember if you have any questions you can submit them via email at STEMIE@unisa.edu.au where UniSA staff can then try and give you an answer.
