  • the stress data analysis system 1 acquires stress data and analyzes the stress data to identify the cause of stress.
  • the stress data analysis system 1 creates possible countermeasures for the cause, and updates the engineering tool by reflecting the countermeasures that have been decided upon for adoption.
  • the stress data analysis system 1 is capable of collecting not only information about the operation of functions prepared in advance in the engineering tool, but also information in the flow of using the prepared functions, thereby making it possible to reduce or avoid stress in a user who continues to use the engineering tool. Reducing or avoiding user stress makes it possible to improve satisfaction in using the engineering tool. As a result, the stress data analysis system 1 has the effect of improving satisfaction in using the engineering tool.

Abstract

Un système d'analyse de données de stress (1) comprend une unité d'acquisition de données de stress (22) qui acquiert des données de stress concernant une situation de stress qui se produit chez un utilisateur qui utilise un outil d'ingénierie, une unité d'analyse de cause qui analyse les données de stress pour identifier une partie de l'outil d'ingénierie qui provoque le stress résultant de l'utilisation de l'outil d'ingénierie, une unité de création de contre-mesure qui crée une contre-mesure qui peut être prise contre la cause, et une unité de mise à jour (36) qui met à jour l'outil d'ingénierie en renvoyant, vers l'outil d'ingénierie, la contre-mesure déterminée comme étant utilisée.
