How to use “Planimeter - GPS Area Measure” on iOS and Android in Manual Tracking Mode.

GPS Tracking Mode: time and accuracy settings.

Tracking Mode is one of the distinctive features of Planimeter - GPS Area Measure app. It can be used to measure track or path distances and to measure areas of objects or territories by  driving/biking/walking around. You have an option to set GPS accuracy (if GPS is available on your device) and time interval for dropping a pin. If both conditions are satisfied, your current location is added to to the track automatically. Please note, mobile GPS provides accuracy ~2-3m in the best conditions, so make sure it is enough to satisfy your particular requirements.

Sometimes you want to measure an area or distance using tracking feature but you need to place waypoints manually only at certain locations and avoid redundant points in between. You can do it by selecting MANUAL option for the tracking time interval

[LONG TOUCH on Track button ]

to see  time interval options for Tracking Mode.  “Set Point”  button will appear at the bottom of the screen. Now when you start tracking,  your current location - green pin - will be constantly updated as long as GPS accuracy condition is satisfied.  When you are ready to add a point to your measurement track -  just touch “Set Point”  button.

Tracking Mode with Manual option is a very handy feature and can be applied for different tasks. For example, it can be used for mapping objects or places for later use or visit.
Another application where manual tracking can be useful is marking your property with poles. First you can manually (by touch) build a pole line on maps  in Planimeter with required distances between pins. Then you can use Tracking with Manual option enabled to visually estimate your current location (green pin) relative to the planned path and red pins (poles) on it. As soon as you are close enough to the planned point you can place a pole and move to the next point.

Described functionality available on both iOS and Android versions of the app.

Pupil Distance Measure for iOS. Important tips and update. How to measure pupillary distance properly.

New update v1.0.3 for the iOS version of Pupil Distance Meter has been released.
We have made some improvements to the measurement process and also included important information on the screen during the measurement procedure. It should help to understand key point for the successful and accurate measurements.

The info button at the upper right corner of the screen provides content-dependent info / help. It means the information shown on touch is related to the current measurement step or state of the app. Thus you can see help tips at each step of the measurement procedure.


The basic and main app states are:
- taking two SUCCESSIVE pictures of a face with a reference (e.g. credit card) automatically during one session. 3 sec interval allowed  to move the camera from the face to fit a new pattern scale.
- marking pupils and reference bounds with the screen rulers on BOTH (!) images
- rulers alignment confirmation using switch at the right bottom corner (have to be done for BOTH pictures)

ONLY after the rulers are properly aligned and confirmed for BOTH pictures - the actual measurement results are shown at the top of screen.

Although all important key points are mentioned in the video



we still see that some users have difficulties with understanding  the measurement procedure and it causes improper results.

The accurate results can be achieved ONLY  if you:
- follow the instruction thoroughly (see video)
- make accurate ruler alignment
- DO NOT MOVE OR TILT OR SHIFT YOUR HEAD AND  REFERENCE (!)  while taking two successive picture. It is VERY important that pictures are taken for the same head and card position (!).  ONLY PART YOU CAN MOVE  between taking 1st and 2nd pictures is YOUR DEVICE.

We hope this info can help you to understand the measurement procedure better and improve your experience with the Pupil Distance Meter app  that is designed to provide accurate PD measurement.

If you have questions or suggestions please contact support@vistechprojects.com, we will be glad to help you.

Pupil Distance Meter on iOS: new approach for accuracy improvement

Our Pupil Distance Meter (PDM) app is currently available on both platforms Android and iOS. Though  these two apps are named the same they use different methods for PD calculation.

We have listened to feedback from Android users and have updated the app webpage with guide and tips how to improve measurements accuracy. The method used in the Android version is sensitive to measurement conditions and requires proper head and reference position and very accurate rulers adjustment. Although the app does image processing and quick automatic measurements, sometimes it is necessary  to correct rulers position manually.

However the app users tend to use the PDM without browsing the guide and following important tips. For such app lack of attention to the details usually causes misunderstanding of the measurement procedure and inaccuracy in calculations.

Based on Android experience we have come up with a new idea for the PD measurement and decided to implement it on iOS platform first. The main goal of the iOS version of the app is to test a new approach, to improve accuracy and consistency of measurement results and app usability in general.

First version of the iOS app offers manual measurements and requires two different pictures of a face for accurate PD calculations. Although we have tried to automate the process of taking pictures, pupils and a reference have to be accurately marked on both pictures manually. Working with two pictures might take more time for a measurement session but it improves accuracy of the results.

Users are still required to follow the instructions and put some effort into learning the measurement procedure, but it is common for such apps and as soon as they are familiar with the app  good results can be achieved.



As we expected the new method appears to be quite accurate and not so sensitive to the measurement conditions but still is very sensitive to accurate rulers alignment on both picturesSimulation and accuracy test results  are presented on the app webpage where you can compare it with usual ruler measurements.

Based on our tests Pupil Distance Meter app for iOS returns more accurate and repeatable results compared to other apps on the market for this purpose. It also shows big improvement compared to our Android version of the app.

We plan to update the Android version of the app with the new method currently used in the iOS version. Any feedback or suggestions are welcome.
