TASK 1 (TRACKING THE USER):
LTUPersonalLogger should be able to track the user by getting regular updates (at a frequency that the user can specify, but have a default value) on the user's location. For example, at the click of a button (e.g., labelled "Track", or some other useful label, or some other widget), and then at the click of another button (or some other UI option), LTUPersonalLogger should stop tracking. When the user stops tracking, the user should be asked (in a dialog box) whether s/he would like the tracked information saved or not, and if so, should save the path information on the phone.
Provide the following features:
i). The user should able to browse previously saved paths and ask LTUPersonalLogger to show them on a screen on a map (e.g., using Google map).
ii). You should use a media/mean/Bayesian filter to filter out outlier points or smooth out the path.
iii). As using the GPS is battery consuming, the app should also be sensitive to battery levels and perhaps stop GPS based tracking or disallow tracking or warn the user if battery levels are too low (e.g., below 20%).
iv). When a tracked path is saved, LTUPersonalLogger should allow the user to compute how many calories were burnt while walking on that path: calories burnt depends on the walking speed (1 mph is around 1.6 km/h):
"Walking speed is an important factor in determining the amount of calories burned. The average walking stroll is less than 2 mph, which burns 136 calories per hour. Turn it into a speed-walking pace of 3.5 mph and your burn rate goes up to 238. At 5 mph (you might as well call this a jog), a person can burn up to 544 calories per hour." [src: https://www.ehow.com/how-does_4569224_many- calories-walking-burn_.html?ref=Track2&utm_source=ask]
The calories burnt also depends on height and weight of a person, which a?ects walking speed. Hence, for this assignment, simply use the following formula:
Calories-burnt = hours-walked * calories-per-hour
= (distance-walked-in-miles / walking-speed-in-mph) * calories-per-hour
= ((distance-walked-in-km / 1.6) / 2) * 136
= distance-walked-in-km * 42.5
(assuming a walking speed on average of 2mph)
TASK 2 (USER CAN ASK FOR RECOMMENDATIONS OF NEARBY POIs: QUERY AND BROWSE THE LOCATIONS AND WALKING PATHS TO POINTS-OF-INTEREST OF A CERTAIN TYPE WITHIN A GIVEN DISTANCE FROM THE USER'S CURRENT LOCATION) : [Coding]
LTUPersonalLogger should provide a user interface to allow the user to enter a distance measure and type of Point-Of-Interest (POI) (e.g., "museum") in order to query (using Google Places API) for particular types of POIs (e.g., museums) within a given distance from the current location of the user. The user can then select one or more POI( s) from the l ist of returned POIs and LTUPersonalLogger should show on a map the selected POI(s)'s location and the walking path to the POI(s) from the user's current location (whatever the user's current location).
For example, using the Place Search feature of the Google Places API (see https://developers.google.com/places/documentation/search), the user can query for museums (POIs of type "museum") within 3000m (or 3km) of where the user currently is, supposing the user is currently at
location=-37.7838757,144.9515533, via this URL:
https://maps.googleapis.com/maps/api/place/nearbysearch/xml? location=-37.7838757,144.9515533&radius=3000&types=museum&sensor=tr ue&key=AIzaSyD4owSfxQjLu-_8ykHy3nJkKL6gai3wOAs
[Note that you should replace the key in the URL above with your own key.]
The response from Google is then a document containing a list of museums within 3km of the user, such as the following:

TASK 3 (JOURNALLING MORE THAN JUST LOCATIONS - moods and photos):
LTUPersonalLogger should provide a user interface to allow the user to record not just the location but also to allow the user to
• express and record moods (which can be selected from a drop-down menu of predefined moods) (which will be geo-tagged and time-stamped and stored on the device), and
• take photos (which will also be stored on the device and geo-tagged and time- stamped); this feature should also allow the user to provide a textual description of the photo.
The app should also allow the user to see on a list of stored mood entries and photos taken by date, and to view on a map the mood entries and photos taken (filtered by date). Some examples of this idea is haze mapping (https:// www.clickz.com/clickz/column/2282206/visualization-map-tracks-sghaze-via- instagram-in-real-time), and ContextWatcher (https://research.nokia.com/files/ 2006_WTAS_ContextWatcher.pdf).
TASK 4 (JOURNALLING MORE THAN JUST LOCATIONS - physical activity of user): [Coding]
LTUPersonalLogger should provide a button to allow the user to turn on/o? activity recognition [using the API at https://developer.android.com/training/ location/activity-recognition.html] and track the activity of the user (e.g., the user is walking, inactive, on a bus, cycling, etc) and to allow tracked activities to be recorded (which will also be geo-tagged and time-stamped and stored on the device).
Then, modify part (iv) of TASK 1 so that only walking distances are calculated.
TASK 5 (SUPPORTING MULTIPLE SCREEN SIZES): [Coding]
LTUPersonalLogger should have a user interface that supports multiple device s i z e s ( e . g. , s e e https://developer.android.com/guide/practices/ screens_support.html).
For this assignment, only two device sizes, namely, a smartphone (e.g., a typical Android phone size) and tablet (e.g., Nexus 7 size, when in landscape orientation), should be supported. For example, it could have the following layouts:
TASK 6 (CACHING)
LTUPersonalLogger should provide an option on the user interface to allow the user to say whether s/he would like to use previously cached results (e.g., the results of URLs/queries to the Google servers via the Google Directions or Place APIs) on the mobile device or simply reissue queries for results. Design a cache to store previous results - you are free to set some limit on the cache size as you see fit.
[NOTE: e.g., to enable caching of retrieved places of interest so that there is no need to reissue queries to Google if the user is around the same location as before, within a fixed range]
TASK 7 [Coding]
GPS currently may not work well indoors. Add a feature to LTUPersonalLogger in order to track indoor location paths, instead of using GPS.
[Note: this feature relies on having indoor maps and an indoor positioning technology; for this assignment, you can draw up your own maps and need only show three locations that your application can distinguish (e.g., PW215, BG115, BG139, or any choice of three indoor locations on the LTU Bundoora campus you choose) - use either triangulation, signal strength measurements, and/or fingerprinting using WiFi signals to determine indoor locations. Since Google APIs may not be available for indoor locations, you need to build your own directions database (among the three locations you choose). For example, if I am at PW215, it should show a path to BG115 or BG139, depending on the user's request. The database of paths can be hardcoded.]
TASK 8
The documentation describing the system should include:
(i). an overview architectural block diagram of the system (including the mobile client(s) and its major components, and server-side components including the Google map servers, etc, used,
(ii) a brief explanation of the architectural diagram given in (i) about how information requests from the mobile client(s) are processed in your system (use test cases and scenario(s) in your explanation), and comment where and why multithreading was used, if at all (in any form),
(iii) a detailed diagram with explanation describing the structure of the mobile client GUI (showing the di?erent screens and how they are related), for the LTUPersonalLogger mobile application [you can use any tool to draw the screens, etc, or even hand-drawn as along as readable and clear], and
(iv) a description of how context-awareness (beyond only location-awareness) might be useful in extending this application (you do not have to implement this). For example, what other types of context information can be used? How can this context information be acquired and processed? (Sketch this and mention what other sensors can be used, etc)
[Relate to material from lectures as much as possible.]
As far as possible, provide rationale for your design - that is, provide reasons for why it was designed that way.
BONUS TASK [10 marks] (for a possible total of 110/100!)
(i) Geofencing [3 marks] Use the geofencing API [https:// developer.android.com/training/location/geofencing.html] to add geofencing around hot POIs so that the user is notified when s/he is within 100m of one of four (predefined by you) hot POIs, and show these hot POIs on a map.
(ii) "Logging nearby WiFi hotspots" [3 marks] Add a feature to LTUPersonalLogger to scan for nearby WiFi access points (hotspots) periodically (e.g., at a user-specified/default frequency) and to save the scanned data on the phone itself (geotagged and timestamped), as a means of creating a personal map of places with a high density of hotspots; and allow visualising, on a map, of these hotspots.
(iii) " Sharing with" Friends [ 4 marks] Add a feature to LTUPersonalLogger where one can share (part of) one's diary of (user selected) paths and information via Bluetooth or WiFi-Direct.
