[samigo-team] Replacing Java applet with HTML5/Flash

Thu Mar 21 13:56:33 PDT 2013

Hi Sam,

The attached PPT document steps through the flow of a student using the 
audio recorder and each step has a Must Have or Nice to Have section. 
Must Haves are deal breakers and need to be addressed before it can 
replace the current recording applet. GUI uses your HTML5 recorder GUI 
with proposed modifications.

Slide #6 has the following requirement as a really nice to have (should 
be must have except that it's not currently supported by the Java 
recording applet). However, would be really nice if could be fixed in 
new recorder so previous attempts, albeit not saved, are accounted for:
       If user makes a recording, then manually loses Audio Recorder and 
re-launches recorder, recorder should count the previous recording 
attempt against the maximum allowed and display the adjusted value for 
attempts remaining on the UI

Please let me know if you have any questions.

Best,
Jackie
