Rating System

Last time, distance metrics were discussed. A star rating system may be an easier way to interact with the system. The rating could also be used to decide what to do next:

  • simply let the user continue with his or her task (e.g. when the user gave 5 stars),
  • propose to let them go through the step-by-step process in the PMT (e.g. when they user gave 2 stars),
  • etc.

Simple using a star rating system is not enough. For example, when the user is at an ATM in a quiet street on the first day, the settings may be excellent and get a good rating, but when the next day he is at an ATM at a noisy location, the rating for the same settings would be different. Context needs to be taken into account. This is the focus of another task (in Cloud4all). Possibly the work on the rating system should wait until the work on context has progressed further?

Early PCP Designs

IDRC presented early designs for the PCP on a smartphone; see the presentations sent on 19 February.

The PCP's initial screen has two options: “Use current device settings” and “Apply Base Set”. When you choose “Use current device settings”, the PCP would grab your phone's settings to create the “Phone Set”. You can also undo this. Swipe down to open the PCP. The top of the screen show that you are looking at the “Phone Set”. You can e.g. adjust the font size; you can go to Advanced Settings to adjust e.g. button size. From the basic preferences, you tap on the device content to go back to the device. The PCP would also allow you to search for certain advanced preferences.

From the main page, you can also choose to apply the Base Set (temporary name) instead of “Use current device settings”. The Base Set is pulled from the Cloud and applied to device. You can undo this. Swipe down to enter the PCP; the drop-down menu at the top gives you access to the Prefs Sets in the phone. (A check mark indicates that you are using the Base Set. When you click on “Other Set”, that set will be applied to the device.) From here, you can also create a new set.

Comments & questions:

  • Preview or inspection? The PMT has some notion of a preview – or survey a larger number of changes. This would not be practical on a phone or a kiosk. E.g. something that involves a lot of noise (...) A preview on the device is quite difficult, e.g. when a person is in a hurried situation (e.g. kiosk) or using a small screen.
  • “Return to content” may not be clear if you mean “go back to the device”. But if that screen was the original content of the screen, and as the user is changing the settings they were applied live to the content or device. So the user could see the adjustments applied. To go back to the content, they would touch the content. This would cognitively be easier to return, and easier to understand the consequences of what they are doing, since the content is at the bottom part of the screen.

  • It is too early for user research; we need more discussion and comments from the Architecture & Preferences point of view. User research is planned for later.

PMT – Basic Functionality

See CERTH's message from 18 February.

PMT - Advanced Functionality

Presented by FhG.

Comment regarding the tools' names: Keep PCP as the smallest one and PMT as the more complex tool. If one the PCP we want more, we can call the other one the minimal PCP.
