Evaluation and Writing
User tests are finished and analysed. Current Status Eleven user tests were done and are evaluated now. Eight people with technical background (either on the programming or on the usability side) were asked and two people, who are not working in the IT sector. The tests included three parts in the end. First, questions about Read more about Evaluation and Writing[…]
Testing and Writing
User tests are nearly completed and more in-app feedback is added. Current Status After a pre-test, the test design was changed and updated again. For example, the acceptance of ultrasound is now checked with a system acceptance scale. Furthermore, the pre-test was used to change the interface to make it more user friendly and intuitive.

Case, Bugfixes and Writing
The Unita beacon hardware got a wooden box to set up and transport the beacon. Current Status The Unita beacon can now be easily set up. The case is made of wood and consists now of three layers. The bottom layer contains a powerbank as power input. The next one has the Raspberry Pi 3 Read more about Case, Bugfixes and Writing[…]
User Tests
To get more data for the evaluation part of my thesis, user tests will be realised. Current Status Beside bugfixing and refining the software, the evaluation of the Unita beacon, with the help of the client test app, will be realised through user tests and questionnaire-based interviews. Alongside the hardware evaluation, those tests will give Read more about User Tests[…]
Software implementation
The implementation Unita SDK, the application on top of it and the server is now completed and only needs more testing, refinement and bug fixing. Current Status The beacon module (Unita SDK) now got the last software parts. The SDK now has the fully implemented WebSocket interface and with that the communication with the server Read more about Software implementation[…]
Application creation
The implementation of the SDK is on the home stretch as well as the use case application Current Status The software implementation for the beacon is going on and nearly finished. On the application side, the main use case is still in progress, but already has many features implemented. The SDK now has a remote Read more about Application creation[…]
Backend
Beside working on the beacon module and application, the server part started! Current Status The software development for the beacon is going on and the application on top of that module is also in progress. The biggest problem for the beacon module was, to stay on a base level and to not include parts of Read more about Backend[…]
Beacon Software
Use cases were defined and the development is in progress. Current Status After finding a suitable interface, I created several use cases. With those use cases, I created a list of features, which should be in the beacon module and on the server side. This module should contain all the basic things needed for the Read more about Beacon Software[…]
Problems with Hardware
After facing a major problem, an important step is done to proceed further in the development. Current Status During testing one big problem occurred with the chosen hardware. The Shield and the USB interface didn’t work as planned. In combination with Lineage OS 15, the shield wasn’t recognizable for the Raspberry Pi. The selected USB Read more about Problems with Hardware[…]
Hardware testing and Software Development
The development of the UNITA beacon is going well and some important question are answered, while new challenges appeared. Current Status After researching for hardware, I made a final decision for the first prototype. I decided to use a Raspberry Pi 3. Therefore, I had to find an interface for analogue input, as the Raspberry Read more about Hardware testing and Software Development[…]
About
The area of Internet of Things (IoT) gained increasing importance in recent years. More and more everyday devices become smart and connected. Most of today’s IoT devices communicate via Wireless LAN or Bluetooth, which requires an external network and available sensors. UNITA focuses on the development and construction of an ultrasonic communication infrastructure, i.e. ultrasonic beacons, which should provide an alternative way of communicating for IoT devices. These beacons should send and receive ultrasonic information and can connect with the internet for data exchange. With those beacons it should be able to create a network, which can be used to connect smartphones, smartwatches and other IoT devices with each other and the internet. As a proof-of-concept, a mobile app should be developed that communicates with the beacons and visualizes the network activity and status. The application will be implemented as Android application.
