Dr.-Ing. Jan-Niklas Voigt-Antons


Jan-Niklas Voigt-Antons joined the Telekom Innovation Laboratories as a research scientist in January 2009 and is working there since 2014 as a senior research scientist. He received his diploma in psychology in 2008 from the Technische Universität Darmstadt, Germany, a Doctor-of-Engineering degree in 2014 from the Technische Universität Berlin, Germany and has been doing research at the Quality and Usability Lab at the Technische Universität (TU) Berlin, since. His research interests are in Quality-of-Experience evaluation and its physiological correlates with an emphasis on media transmissions and human-machine-interaction, including neural processing of multimodal interaction. During summer 2012 he was visiting researcher at MuSAE Lab (INRS-EMT), Canada where he examined neural correlates of quality perception for complex speech signals. In spring 2014 he was visiting researcher at the department of psychology of NTNU, Norway where he examined neural correlates of audiovisual asynchrony.

Abstract Background: Mobile application-based therapies are increasingly being used in the rehabilitation of people with aphasia (PwA). Mobile apps can increase the intensity of treatment and have been shown to result in meaningful outcomes across several domains (Des Roches & Kiran, 2017). Despite the proliferation of available apps for aphasia therapy, very few have been designed with input from relevant stakeholders, using principles of user-centered design (UCD). The VoiceAdapt app is a multimodal adaptive language training app for aphasia, designed using a UCD approach with relevant stakeholders (people with aphasia, caregivers, clinicians). Aims: We describe the UCD process undertaken by the VoiceAdapt consortium in the design and development of app-based training. Experts and potential end users were consulted in identifying relevant requirements and functionalities, developing user interface prototypes and performing evaluations in an iterative fashion. The research questions related to: 1) identifying barriers to app-based training (specifically) and rehabilitation (in general); 2) factors affecting motivation for PwA to take part in rehabilitation; and 3) optimizing user experience and training impact. Method: Procedures. Following international standards (ISO 9241-210:2010), the main UCD activities in the project encompassed: understanding and specifying the context of use, eliciting user requirements (using guideline-based structured interviews), designing solutions (mock-ups, prototypes) and evaluating the designs against requirements (focusing on user experience of multimodal speech interaction and adaptivity) over the course of three iteration cycles. Participants. In total, 75 participants (26 PWA, 36 medical experts/caregivers, 9 interaction-design experts, 4 informal caregivers) from Austria and Germany were involved across the four components (requirement interviews, three iteration cycles) of the UCD process conducted thus far. Results: Stakeholders interviewed during the requirements phase identified the following as required elements for the app: regular training opportunities (requiring persuasive strategies), adaptivity and personalization (allowing individual training and support), cooperation between therapist and PwA (and family members), and multimodality training (reading, writing, understanding, production). When exposed to functional prototypes of the training app, participants responded positively to the voice interaction offered (verbal expression training was a priority) and adaptation of difficulty level. In addition, participants expressed the app should be designed for co-experience/co-usage, as many PwA required assistance to perform the exercises, but stated they preferred this as it mirrored their interactions in everyday life. Discussion and Conclusions: The results of our adapted UCD process confirmed the benefits of the central features of our training app (voice interaction, adaptivity), but also generated a number of insights. We found that interviewing PwA in group settings was beneficial (and was even enthusiastically requested). We conclude that the presented UCD process has enabled the successful development of a training app that will form the basis of a clinical RCT (Kim & Rochon, 2019) beginning in 2020.
