Abstract
The present disclosure provides a method of measuring a path length using a handheld electronic device comprising an acceleration sensor. The method comprises: sensing an acceleration of the handheld electronic device while the handheld electronic device is translated over the path, thereby obtaining an acceleration plot of the handheld device; and calculating the path length from the acceleration plot using an integration procedure. In some cases projection of a distance over a required measured path is used.
Claims35
A method of measuring a path length using a handheld electronic device comprising an acceleration sensor, the method comprising, using a processor for:
- sensing an acceleration of the handheld electronic device while the handheld electronic device is translated over the path, thereby obtaining an acceleration plot of the handheld device;
- and
- calculating the path length from the acceleration plot using an integration procedure.
The method according to any one of the preceding claims, wherein said handheld electronic device is a smart-phone.
A non-transitory computer-readable media storing computer-readable instructions that, when executed by a handheld electronic device translated over a path to be measured, cause the handheld electronic device to measure the path length by:
- sensing an acceleration of the handheld electronic device while the handheld electronic device is translated over the path, thereby obtaining an acceleration plot of the handheld device;
- and
- calculating the path length from the acceleration plot using an integration procedure.
The non-transitory computer-readable media storing computer-readable instructions of claim 38, said integration procedure comprising:
- computing a set of velocity plots by integrating the acceleration plot over a set of integration intervals, wherein the integration intervals have a decreasing span and exclude a growing initial portion of the acceleration plot;
- computing a set of distances by integrating the set of velocity plots;
- and
- estimating the path length based on the set of computed distances.
The non-transitory computer-readable media storing computer-readable instructions of claim 38, said integration procedure comprising:
- identifying the start and end point of the movement;
- and
- integrating between the start and end points of the movement to find the path length.
A handheld electronic device configured to measure a path length, the handheld electronic device comprising:
- an acceleration sensor configured to sense an acceleration of the handheld electronic device;
- computer memory;
- and
- a processor operatively coupled to the memory and to the acceleration sensor, wherein the memory includes instructions for causing the processor to:
- sense an acceleration of the handheld electronic device while the handheld electronic device is translated over the path, thereby obtaining an acceleration plot of the handheld device;
- and
- calculate the path length from the acceleration plot using an integration procedure.
A measuring module for a handheld electronic device, the measuring module configured to measure a path length and comprising:
- a user interface to receive user input indicative of a starting and an ending of a translation movement of the handheld electronic device over the path;
- a data receiver unit configured to obtain from an acceleration sensor an acceleration plot of the handheld device, the acceleration plot being indicative of an acceleration of the handheld electronic device while the handheld electronic device is translated over the path;
- a data processing unit configured to calculate the path length from the acceleration plot using an integration procedure;
- and
- an output unit configured to output the calculated path length to a user.
