The bottom line with a car UI is that a good one has only one rule, the UI is about one thing, and one thing only: drivers can easily accomplish tasks. Everything else, including look and feel, are secondary issues. They should be considered mainly to evaluate how they're contributing to the one rule.
So: in evaluating this purported 7.0 leak, the question is, will it make drivers more successful at accomplishing tasks, or not?
I think the two top factors that go into measuring the "success" or "failure" of accomplishing a task are:
• time it takes to do the task
• can driver to accomplish the task without looking
The aesthetics are way down the list, imho.
If when 7.0 comes out, drivers get things done sooner, easier, with less hassle due to better info chunking, info hierarchy, and step count reduction, then it's a success.
I agree with this.
Critical information display on the dash has priority. For the driver of an electric car these should be things such as (in order):
- Real time vehicle operational data - Speed, sensor inputs, power usage, etc...
- Vehicle status - Charge/range, control states, operational modes, etc...
- Auxiliary info - Odometers, trip meters, power averages, navigation, etc...
Given the dynamic capability of a fully digital display, there's some room to pick and choose what auxiliary info to present. But don't make the items in the first two categories an either/or decision... or compromise their presentation for the sake of presenting less critical info, or for stylistic reasons.
And make logical choices about what to group/offer for dash presentation given you also have a fully digital center console.
Example 1: I find the 7.0 presentation of the power graph somewhat compromised... for the scaling/labeling issues earlier, as well as the fact it removed the comparison to rated range, and thus presents less info.
Example 2: The "since last charge" display appears more visually cluttered, yet doesn't seem to present any new data. However it appears you would have to drill in to it in order to get odometer data that is no longer presented elsewhere.
Example 3: The power meter is no longer statically integrated with the speedo. Thus of you want a power meter, you have to take up a "side panel" slot for the power meter/graph display. Given that you can also get power averages on center console you don't NEED the power graph on the dash, yet you now no longer have the option of using that side panel for something else if you want the power meter. In other words, the option for trip meters, speedo/power-meter, and one other option (media, phone, etc...) all on the dash simultaneously is no longer an option.
It appears that auto pilot may have been the primary focus, with the "traditional" controls tucked in around it.
