  1. Footholds for Design Shahaf Gal

  2. Main Ideas • Ray and his bridge • String, different types of wood, glue, 3 weeks • The process of design • Experiments, revision, reflection • How tools should interact with people • Growltiger • spreadsheets

  3. Ray the top-down designer • Goes to the library • Reads some books • Watches some movies • Draws some bridges • Evaluates his final designs… and they don’t work!

  4. Another Approach • Reflection • Ray prepares 6 designs for a bridge • Uses growltiger to reflect on his design • Eliminates 4 designs • Experiments • Lab experiments • Tests materials strength

  5. Revision • Finalized overall design • Added some final pieces • Took 4th place

  6. Ray’s use of software • Growltiger helps Ray form a conceptual framework • Image foothold • Allows for reflection

  7. The spreadsheet(why is it so useful) • Representation • Interactive Modification • Incremental Programming

  8. Things to think about • How should software tools interact with people? • Does Ray’s design process translate to software? • Is Dr. Turner going to relate this back to Herb Simon?
