...the voice process is too slow for a real threat. ...I think it takes a fraction of a second to take in with peripheral vision the clock face display indicating the direction of the threat, almost simultaneously scanning outside the cockpit. Right - Voice is not the fastest. It takes a while for the message, and it can get lost (for example if you're receiving a radio message). The fastest is a large simple graphical "pointer" in your field of vision, accompanied by a warning alarm. A visual presentation is less effective when: - its not already in your field of vision (turning head takes lots of time) - poor contrast - a complicated/busy/fussy display cannot be comprehended instantaneously - buried low on the panel Voice helps in the above situations... Here's the SN10 presentation (4 O'clock high): http://www.nadler.com/sn10/FLARMcol.png We also changed the Butterfly presentation from the original to make comprehension instantaneous... Hope that helps frame the problem! Best Regards, Dave PS: We built many voice applications (phone), some quite notorious ;-) Time for user to comprehend and use is always an issue. Think about various annoying automated phone services you've used. |
