People, Trees, & User Experience
In the most simple terms, what we see, is how we feel.
Comfort matters: then, how do we prune trees for viewing comfort ?
How we see a landscape, whether we see landscape in comfort, or if the view experience is uncomfortable determines how we accept a landscape. In other words, if we view from comfort, we are more likely to appreciate a view, and feel that we like the view.
What we feel is based on the types of shapes that we see around us.
1) What we see first, are the trees slightly above our heads
approximately 15 degrees up, to 10 degrees below horizontal eye level.
2) Our viewing comfort is 0 degrees horizontal to 10 degrees downward.
This illustration on the left shows the visual comfort zone as studied and determined by Henry Dreyfuss.

The Measure of Man: Human Factors in Design, Henry Dreyfuss
Physical Condition: – physical discomfort occurs at 25 degrees upwards from horizontal being the maximum upward rotation of our eye movement,
Reaction: – a wall is perceived to be ‘a wall’ at a 27 degree incline upwards from horizontal.
Result: – our brains ‘borrow scenery’ (shakkei) when the visual is 8.3 degrees upwards and located between 9.4 degrees and 7.2 degrees (Higuchi)
a DISTANT COMPRESSED VIEW: SHUKKEI
Garden Design Position: – Compressed View is positioned 9.4 degrees and up and lower than 7.2 degrees, leaving a gap
– the brain compresses reiterated data because of organization and position of objects at these angles for quicker reference with ‘danger / no danger’, while observing the uncluttered central ‘borrowed view’.
Reaction: – higher levels of data above and below create a ‘space between’ these angles so that the framing causes our brain ‘to borrow’ a view as shakkei that see’s the lesser details of the main view,
Result: – our brain compresses and ignores, the up or down view and separates data from the borrowed view – utilized in design as a ‘compressed view or condensed view’* (shukkei).
