Exercise 28: Integrating Plato with Grace
Summary
The goal of this exercise is to integrate the Plato engine with the Grace UI, and to demonstrate the temperature() functionality.
 | Combine the Grace and Plato projects into a single solution. |
| Create data files (.txt) to represent each of Plato's data structures, and have Grace load those into memory when it initializes. |
| Every 5 seconds, have Grace examine the file sizes and reload them as needed. |
| Create a new data structure for Grace which will represent the phrases that will be recognized. They may use entity types, such as: |
| | what is the current temperature in {city}? |
|
|
| Optional words are denoted with round brackets, and vertical bars can be used to denote several options. For required words that have several options, use square brackets. For example: |
| | [what is|what's] the (current) temperature in {city}? |
|
|
| Transform these specifications into an SR grammar, write it to disk, compile it, and then load it. |
| When a statement is recognized, pass it on to Plato. |
| If Plato can't parse the statement/question, abort all operations. Simply do nothing. |
| If Plato's output is a value, display it and speak it. |
| If Plato's output is an assignment or relationship, briefly display a full-screen green window. (1 second) |
| If Plato's output is a TransOutput_Program, display a full-screen gray window while the query executes. If the query completes properly, display and speak the answer. If it fails, display a full-screen red window for 1 second. |
| Test the setup in a kitchen with a laptop, speakers, and a Bluetooth headset. |
