TrackLab™ Indoor and outdoor movement tracking and analysis

TrackLab: indoor and outdoor tracking

Sensors● GPS in specialized sensors and smartphones● Ultra wide-band (Ubisense)● Network of stereo video sensors (EagleGrid)● Multi-camera video tracking (PeopleTracker)● Tracking data enhanced by accelerometers and

inertial sensorsMaps● OpenStreetMap for outdoor tracks● Calibrated bitmaps for indoor tracksMode● Live or offline

EagleEye

● Stereo camera sensors● Ceiling mounted ● No tags/markers needed● Identification: yes● Re-identification: no● Accuracy: +/- 50cm (depends on conditions)● Trackable area: app 13m2 at 3m camera height● Indoor tracking when wearing tags is not possible

Stereo camera sensors

Ubisense

● Ultra Wide Band● Wall mounted● Unique tag worn by test subject● Identification: yes● Re-identification: yes● Accuracy: 30cm in real life situations● Trackable area: 40x40m with 4 sensors● Indoor/outdoor tracking when using tags is

possible

UWB Sensors and tags

PeopleTracker

● Multiple video cameras● Under development ● No tag needed● Identification: yes● Re-identification: yes● Trackable area: depends on number of cameras● Tracking up to 10 people simultaneously

without markers or tags

Movement Classification

Behavior detectionWho is doing what and where?

● Movement analysis based on speed (e.g. walking, running) or accelerometer data

● Detect mode of transportation (e.g. train, bus, bike, by foot)

Application examplesFor Ambient Assisted Living

● Assessing both positive and negative aspects of a person’s location and movement

● Monitor exercise taken by the subject, reports can be used to give feedback to patients and caregiver

● Integration with other software makes it possible to send an alarm signal to caregivers, for instance if an Alzheimer’s patient strays outside of the grounds of where they live

● Detect if a person hasn’t moved for a while, which can trigger an alarm

● Research tool in development of in-store navigation systems

● Navigation assistance● Personalized advice● Driven by tracking and behavior

detection software

Application examplesE-coaching apps for in-store navigation

Application examplesE-coaching apps: pilot study - 1

● Group of older subjects (average age 72) were asked to locate 15 products on a shopping list in a simulated shop

● Tracked with TrackLab software● Input ultra-wideband tracking system from Ubisense● The participants were given instructions for finding

recipe ingredients using 5 different navigational methods:

● No help● Voice guidance● Floor plan● Haptic feedback system● Navigational arrows on a smartphone


● Analysis:● Path distance● Time until reaching food’s location● Meander until reaching food’s location● Time standing still

● Conclusion: ● Map easiest and most efficient manner to navigate● Build on familiar methods when designing new tools


● Group of older subjects (60-80 years) make a shopping list with 8 products using the app

● Use the navigation section to walk to the store● Check home status before leaving● Do the groceries using the path the smartphone shows● Call taxi


● Tracking using foot sensors


● Results:● All participants would use a device if

it helps them● Suggestions by family members,

informal or professional caregivers appear less important

● Concerns: technical difficulty, privacy, safety

● People are willing to pay (€5-25 / month)
