An immersive care environment for DVT patients
DVT patients frequently wear DVT compression socks as a precautionary measure to avoid emergencies such as pulmonary embolism. TESSA is an immersive environment for DVT patients, with the smart compression sock acquiring health data and the smartphone app and Google Home watching the patient's diet and activity.

The chatbot asks Beat what he had for lunch. Beat takes a picture of what he had and sends it to the chatbot. The image recognition AI recognizes the food based on the picture and suggests a healthier meal by sending him a recipe. When Beat comes home from his daily exercise, he asks the bot how much he ran today via Google home.
The compression sock tracks the user's vital signs and identifies symptoms of life-threatening conditions. In emergency scenarios, the compression sock uses its integrated GPS to notify the nearest secondary healthcare provider. Live health data is sent to the healthcare provider so that the situation can be assessed before the treatment.
Primarily, the sock focuses on emergency prevention - the wearable device detects the patient's vital signs that are relevant to emergency pulmonary embolisms such as pulse, heart rate, and body temperature. When it discovers signs of an emergency, the bot quickly asks the users if they're okay via the smartphone app. When there is no response, the app immediately sends an ambulance to the sock's GPS location.
Using littleBits, we succeeded in creating a basic working prototype of a sock that makes a phone call to the designated number when the user presses the button attached to the sock. For the smartphone app accompaniment, we designed and prototyped a basic chatbot app interface. We also made a voice-based chatbot prototype that can respond to users' voice commands via Google Home.
We prototyped the sock prototoype with LittleBits, the voice interface with Google home and Sayspring, and the second iteration of the iOS app with inVision. Unfortunately, we couldn't get the footage of us interacting with the voice prototype. However, we successfully prototyped a conversation with TESSA checking on Beat's activity and heart rate that day.
Project TESSA was in many ways a valuable opportunity. It was my first time doing a project with a client company. The project allowed me to explore various new topics of UX: voice-based interaction with a chatbot and interacting with physical objects.
Since the class timeline for this project ended with presenting the prototype, we didn't have time to conduct user interviews and testings. If we had more time, we would definitely visit DVT patients and validate our ideas and concepts.
