What's the distance value when the visible surface is beyond the max value?

[xiuqijix]

In previous version, the value is defined between the maximum sensing distance and the minimum sensing distance:

The current device proximity is a value that represents the proximity of the hosting device to a physical >object (i.e., some value between the maximum sensing distance and the minimum sensing distance).

In latest spec, the value isn't limited but there is a sensing range description:

Note: If the implementation is unable to provide the near value, it could infer the near value from the >value of distance. For example, if distance is not equal to max, it could imply there is an object in the >sensing range.

I want to know when there is no object in the sensing range, what's the distance value?

From the Generic Sensor spec, since

The value of all latest reading entries is initially set to null

I would say, distance value would initially (or when there is no object in sensing range) be null

[anssiko]

It'd be logical for the attribute to be null if not within the sensing range.

Proposal: add the following to https://w3c.github.io/proximity/#proximity-sensor-distance:

If the object is outside the sensing distance, it must return null.

Comments?

I agree, that will be clearer for end user.

I submitted a PR to address this issue (and #29), see: https://github.com/w3c/proximity/pull/31

Thanks @anssiko, the issue had been addressed in https://github.com/w3c/proximity/pull/31, close it.
