Enabling Real-Time Feedback in Software Engineering

Modern software projects consist of more than just code: teams follow development processes, the code runs on servers or mobile phones and produces run time logs and users talk about the software in forums like StackOverflow and Twitter and rate it on app stores. Insights stemming from the real-time analysis of combined software engineering data...

The Vibe of Skating: Design and Testing of a Vibro-Tactile Feedback System

Providing athletes with real-time feedback on their performance is becoming common in many sports, also in speed skating. This research-by-design project aims at finding a tool that allows the speed skater to get real-time feedback on his performance. Speed skaters often mention a so-called “good feeling” when skating behind a better skater. It...

The learning process of gait retraining using real-time feedback in patients with medial knee osteoarthritis

The objective of this study was to investigate the learning process of knee osteoarthritis (KOA) patients learning to change their foot progression angle (FPA) over a six-week toe-in gait training program. Sixteen patients with medial KOA completed a six-week toe-in gait training program with real-time biofeedback. Patients walked on an...

Effect of real-time biofeedback on peak knee adduction moment in patients with medial knee osteoarthritis: Is direct feedback effective?

Background: Gait modifications can reduce the knee adduction moment, a representation of knee loading. Reduced loading may help to slow progression of medial knee osteoarthritis. We aimed to investigate the response of patients with medial knee osteoarthritis to direct feedback on the knee adduction moment as a method for modifying the gait...

Gait retraining using real-time feedback in patients with medial knee osteoarthritis: Feasibility and effects of a six-week gait training program

Background: The knee adduction moment (KAM) is often elevated in medial knee osteoarthritis (KOA). The aim of this study was to evaluate effects on KAM and patient-reported outcomes of a six-week gait training program. Methods: Twenty-one patients (61 ± 6 years) with KOA participated in a six-week biofeedback training program to encourage...

Wireless instrumented klapskates for long-track speed skating

In the current project, we aim to provide speed skaters with real-time feedback on how to improve their skating performance within an individual stroke. The elite skaters and their coaches wish for a system that determines the mechanical power per stroke. The push-off force of the skater is a crucial variable in this power determination. In...

Real-time haptische terugkoppeling aan schaatsers: Gebruik makend van een draadloze actuatormodule

De GonioTrainer is een draagbaar apparaat dat schaatsers helpt bij het verbeteren van hun schaatstechniek. In deze thesis wordt een manier besproken om het huidige prototype van de GonioTrainer te verbeteren en real-time terugkoppeling te geven naar de schaatser, middels een trilmotor die draadloos wordt aangestuurd. Belangrijke eigenschappen...
