1. Converting Viewing Angle from Degrees to Radians:
viewingAngleRad = deg2rad(viewingAngle)
2. Height of the TV Center from the Floor:
tvCenterHeight = eyeHeight + (viewingDistance × tan(viewingAngleRad))
3. Height of the Bottom of the TV from the Floor:
tvHeight = screenSize × 0.49
tvBottomHeight = tvCenterHeight - (tvHeight / 2)
1. Convert Screen Size from Diagonal to Height:
tvHeight = screenSize × 0.49
2. Vertical Distance from the Viewer’s Eye Level to the TV Center:
verticalDistance = | (tvHeightFromFloor + (tvHeight / 2)) - eyeHeight |
3. Calculate the Viewing Angle:
viewingAngleRad = atan(verticalDistance / viewingDistance)
viewingAngle = rad2deg(viewingAngleRad)
