14. Grant Examine in real world Control Design Realization
Suggestions Manipulation software design is hard Based on a
research of GIS applications and the requirements of the GRASS
community will be validated concepts by: Usability testing
(detailed in next presentation) probably with students Remote
usability testing preferably with GRASS users VNC (Virtual Network
Computing) Virtual meeting service Skype Design cycle Petr Voldan
