- KonferenzbeitragBinarySwipes: Fast List Search on Small Touchscreens(Mensch und Computer 2019 - Tagungsband, 2019) Hartmann, Johannes; Schirmer, Maximilian; Echtler, FlorianSmartwatches and other wearables generally have small screens, thereby complicating touch-based interaction. Selection from a long list, e.g. to locate a contact or a music track, is particularly cumbersome due to the limited interaction space. We present BinarySwipes, an interaction technique based on binary search which is designed to speed up list search tasks on space-constrained screens. We evaluate a prototypical implementation of BinarySwipes on a smartwatch. Results from our evaluation with 21 participants show improved performance over a plain linear search on lists with 100, 200, and 500 entries, but also increased mental load on the users.

- KonferenzbeitragCONTEX(T)PLORER: A Mobile Inspector for Ubiquitous Environments(Mensch & Computer 2014 - Tagungsband, 2014) Schirmer, Maximilian; Bertel, Sven; Wilkening, Ronja LarsThe complex invisible interactions between components of ubiquitous environments present a challenge for end-users and thereby raise concerns of privacy and nontransparency. In this paper, we introduce CONTEX(T)PLORER, a mobile inspector system that aims at lowering the acceptance barrier of ambient intelligence and ubiquitous computing environments. The inspector actively involves end-users in an in-situ investigation process: users select, explore, and inspect components in a ubiquitous environment while interacting with them. Individual components are used as entry points to the process. We present a brief overview of the system’s concept and implementation, and discuss related work.
- KonferenzbeitragContexto: Leveraging Energy Awareness in the Development of Context-Aware Applications(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Schirmer, Maximilian; Bertel, Sven; Pencke, JonasWe introduce a new context classification and recognition framework for the development and deployment of mobile, context-aware applications. The framework is complemented with an energy calculator that specifically assists mobile developers in estimating the energy footprint of context-aware applications during the development process with the framework. The framework abstracts from the raw context information gathering, allows for sensor fusion, enables the prediction of custom and higher-level contexts, and provides for context sharing.
- WorkshopbeitragSens-ation: Eine Plattform zur Entwicklung ubiquitärer Umgebungen(Mensch und Computer 2007: Interaktion im Plural, 2007) Beckmann, Christoph; Schirmer, Maximilian; Paul-Stueve, Thilo; Gross, TomIn diesem Beitrag stellen wir die sensorbasierte Plattform Sens-ation vor, welche sowohl eine Grundlage zur prototypischen Umsetzung konzeptioneller Modelle von kooperativen ubiquitären Umgebungen darstellt, als auch die Evaluation der gedachten Konzepte hinsichtlich deren Machbarkeit, Systemverhalten und Skalierung erlaubt. Universelle Schnittstellen und ein komplexes Anfrage- und Benachrichtigungsschema sind zusätzlich zu einem detaillierten Ereignismodell Kernbestandteil der Plattform.
- KonferenzbeitragSoftware-based energy requirement measurement for smartphones(INFORMATIK 2012, 2012) Schirmer, Maximilian; Höpfner, HagenEnergy is one of the most limiting factors for Smartphone-based computing. There exist various approaches for optimising or reducing, respectively, energy requirements in this context. In order to evaluate these techniques, one has to comparatively measure energy requirements. Most precise energy measurement is subject to attaching measurement hardware to the energy demanding system components. In this paper, we survey alternative software-based measurement approaches that utilise sensor data gathered from built-in energy-related sensors. We illustrate how they can be used and discuss their applicability while considering different operating systems and energy sensors.
- KonferenzbeitragTowards a user-centred planning algorithm for automated scheduling in mobile calendar systems(INFORMATIK 2012, 2012) Halang, Christoph; Schirmer, MaximilianAgreeing on appointments and scheduling time slots with multiple participants is a complex task and remains a challenge in our everyday lives. Despite the technological advances in the areas of mobile computing and cloud storage, these planning processes are still tedious. In this paper, we propose a user-centred planning process for scheduling appointments between users. We describe the algorithm derived from the process, and present a first prototype for a mobile calendar application that implements the proposed process.
