## 5 Experimental Setup

#### 5.3.3. Quantitative Evaluation at Interaction Level: Response Time  
Table 9 includes the average time of response of both KIDE4 Guide and KIDE4 BinPicking. As it can be observed, the response times for each adaptation are very fast, which are endorsed by the results obtained from the user questionnaires for the speed aspect, reported in Section 5.3.1. However, it is worth discussing the difference in response times between use cases. On the one hand, the guide use case is more complex in its modelling, and therefore a single destination can be referred in different ways, explicitly or implicitly (for example, through an object contained in said destination or an action that can be performed in it). Due to this variety of interactions, the response times may increase. This can be seen in Examples (13) and (14), where a television is required, but it is referred differently: Example (13) sets a restriction on all the meeting rooms available, whereas (14) just requests for a television. Between the 2 examples there is a difference of 0.3 s, which is explained by the difference in complexity between requests. These examples also show that confirmations/negations also require a very low amount of time to process. 1. **User. ** \"Quiero una sala con television\" \"I want a room with a TV\" 2. **System:** \"Tengo demasiadas opciones que se corresponden con _sala con television_. ?Te parece bien que te guie hacia la Puer de la sala de reunion Sua 2?\" \"I have too many options that correspond with _room with a tv_. Is it okay if I take you to the entrance of meeting room Sua 2?\" **[Time elapsed:** 2.17 s] 3. **User. ** \"si\" \"yes\" 4. **System:** \"iYa est! ?Neecitas algo mas?\" \"Done! Do you need anything else?\" **[Time elapsed:** 0.19 s] 1. **User. ** \"Quiero ver la television\" \"I want to watch TV\" 2. **System:** \"Tengo demasiadas opciones que se corresponden con _television_. ?Te parece bien que te guie hacia la Puer de la sala de reunion Aura 1?\" \"I have too many options that correspond with _TV_. Is it okay if I take you to the entrance of meeting room Aura 1?\" **[Time elapsed:** 1.87 s] 3. **User:** \"si\" \"yes\" 4. **System:** \"iYa est! ?Neecitas algo mas?\" \"Done! Do you need anything else?\" **[Time elapsed:** 0.16 s]  
As for the bin-picking use case, the complexity of the scenario is simpler and, thus, the time required to process user commands is lower. This can be observed in Examples (15) and (16). In Example (15), the system only takes 0.87 s to process the initial command and to detect that there is one argument (the destination container) missing and, in Example (16), if the user command contains all the necessary information, it takes 1.11 s to process the whole command. As in the guide use case, affirmations/negations take around 0.2 s to process. \begin{table}
