update for 16.1 bugs fixed

-a QR-code Image attached over Passive Sensor acts as a dynamic reference base added, by accidental change of pelvis position intra-operatively the app updates the position of registered points in AR according to the new position of patient pelvis respectively without to reregister. -to reduce the error during registration of anatomical point, three point should be registered in space around the region of interest in order to define the final registered point - a centroid- respectively

Update to 14.0 iOS also -Calibration now is Independent from iPhone Model settings device. -Added Calibration for X, Y, Z buttons work also in dynamic environment -new function transforming and dynamically changing their geometry Adding a new function to transform spheres and cylinders dynamically and change their geometry - Add the GO button for a smooth transition to the dynamic environment (avoid sudden jumps) -The acetabular axis is presented as rod in AR, perpendicular to acetabular rim circumference.The respective angles of inclination and antevesion between the acetabular axis and projected planes are also measured . - Add buttons for dynamic tool shaft length change. (L)

-undo and calibration buttons enlarged -The method of selection the registration points of the Superior Iliac Spines (ASIS) (P4,P5) and symphysis pubis (P6), by selecting three points over the region of interest each time, is different, in an effort to reduce the positional registration error by simply selecting only one point for each time respectively. For every three points of registration - three green spheres appears and in the centroid position between these points in space a light blue sphere appears which represents the final registration point of interest. -A grey cylinder appears starting from centre of rotation of patient acetabulum - the acetabulum axis of the patient acetabulum- the static values of OI-Operative Inclination OA-Operative AnteversionRI-Radiographic inclination RA-Radiographic Anteversion AA-Anatomical Inclination AA-Anatomical anteversion are measured and printed over the screen in parentheses before the dynamic values respectively.

-updated and optimised the calibration procedure namely positional calibration of pointer tip sphere in AR can be easily done by allowing the user to adjust the XYZ position of the pointer tip sphere by pressing the appropriate buttons accordingly. This feature enhanced the accuracy of App while making easily available to every i-phone model. -Point button removed so simply touching the screen the points are registred. -Pelvic tilt makes common navigation systems referring to the anterior plane inaccurate. The patient-specific pelvic tilt is incorporated in measurements and thus calculated tilt-adjusted values of anteversion and inclination (operative, anatomic, radiographic). This offers major advance compared to manual or common very expensive navigational systems by eliminating completely the innate errors of pelvic tilt. -The new redefined the safe zone according to pelvic tilt are taken into account and added in calculations( Murphy AB and & The Safe Zone Range for Cup Anteversion Is Narrower Than for Inclination in THA William S. Clin Orthop Relat Res (2018) 476:325-335 ). -Pelvic tilt is measured as anterior pelvic plane (APP) Angle and printed with - or + values.
