Material Object Reality,
What do we mean by that? It is observer independent, ie. doesn't have to be sensed or measured to exist. So, it is not limited by being relative to an observer or few observers. It is the source of all relative perceptions or measurements of it via ‘sensory’ input processing (Whether inorganic device or organism observer).
What is meant here by an observer? Something that receives sensory stimulus input reflected or emitted by an existing object in Object reality, the external environment, and processes it into a measurement or observation product that can be called Image reality, or is an element of Image reality, and is different from the input. An observer as described here can be called (or contains) a reality interface. The observer has a viewpoint, its unique position and location, affecting what portion of the sensory stimuli in the environment can possibly be received.
An element of Object reality exists and has orientation and spatial relations to other existing things without these being necessarily known by an observer or measurement.
Here we come across a limitation of description.
A stick material object, for example, has a relative spatial separation, which my be unmeasured, from each object in proximity without the individual separations having an attributed length (the result of measurement with standard scale). This being so, it has a position within the pattern of all existing, without the need for the position to be defined within a co-ordinate system and without need for measurements. Measurements that would allow understanding and communication of a where it is. It, the stick, for example, also has spatially extended existence without its length being measured.
The relative context is needed first before, ‘measured or observed this way’ is decided.
Prior to measurement or observation It doesn’t have a singular (relative) state that has been isolated from the absolute existence, to be identified nor quantified.
