User Interface: <unk>vocalsound<unk> Okay. Industrial Designer: <unk>vocalsound<unk> Marketing: <unk>vocalsound<unk> Project Manager: <unk>vocalsound<unk> So <unk>gap<unk>. <unk>vocalsound<unk> So let's see the <unk>disfmarker<unk> what did you prepare. User Interface: Yeah, so can you go out to the shared folder? Mm the shared folder. Project Manager: Sh share folder for th your presentation? User Interface: Yes. We have a presentation. Project Manager: Because I have here <unk>disfmarker<unk> Industrial Designer: <unk>vocalsound<unk> User Interface: <unk>vocalsound<unk> Uh <unk>disfmarker<unk> <unk>gap<unk> So I got the participant uh three. W uh <unk>vocalsound<unk>. Three. It's the final design, yeah. Project Manager: Okay just one <unk>gap<unk>. Industrial Designer: <unk>vocalsound<unk> User Interface: <unk>vocalsound<unk> S so so I discussed with Guillaume. Industrial Designer: Mm. <unk>vocalsound<unk> Yeah. User Interface: Right. <unk>vocalsound<unk> And uh <unk>vocalsound<unk> so we have <unk>vocalsound<unk> <unk>disfmarker<unk> and we we are both agreed on some two versions of the prototypes, because we were no not decided whether we wanted to have an L_C_D_ or not because it's too expensive. So we come up with two versions. One with and one without L_C_D_s. Um but both comes with a charger and then detachable and uh or <unk>gap<unk> control module. And detachable big buttons for all people um. So <unk>vocalsound<unk>. Industrial Designer: <unk>vocalsound<unk> S okay so I'll show you the the two prototypes <unk>vocalsound<unk>. Here
  Question: Summarize the presentation about two versions of the prototype.
  Answer:
output: Industrial Designer and User Interface gave a presentation about two versions of the prototype, one with and one without LCD. As for the one with LCD, users could choose the direction and if they pushed on it, it's considered like an enter function. There was also a button which was like a mouse. This prototype had microphone arrays for the speech recognition system and switch for controlling. The remote control needed rechargeable batteries, but the type and the number of batteries were not sure. This prototype cost fifteen dollars and it was high above the budget. The second prototype was basically the same as the first one. However, it used buttons to navigate and enter. This one cost four dollars. The remote control had different modules for different groups of people. The set might use a material like titanium or lithium. User Interface said that features which cost much could be optional so the price could be flexible. Project Manager said that the cost of the whole second plan was below the budget.
