In order to achieve this, surveys were applied. Also, GUI design principles were analyzed in the context of WESST-OT. Finally, the goals, objects, methods and rule selection quantitative model (GOMS) was applied. The information acquired was used to enhance WESST-OT’s GUI and at the end was validated following the same methodology. %K WESST-OT %K GUI %K GOMS %K Validación %K Interación hombre - Computar %K Producción intelectual registrada - Universidad Icesi %K Sistema & Telemática %K Validation %K Interaction %~ GOEDOC, SUB GOETTINGEN
