Couples in long-distance relationships (LDR) want to keep in touch, share emotions and feel connected despite the geographical distance. Current approaches to solve this problem include dedicated objects, common communication channels and mobile applications (apps). To combine the advantages of all three approaches, this paper introduces a hybrid approach(More)
Electric Vehicles (EVs) are an emerging technology and open up an exciting new space for designing in-car interfaces. This technology enhances driving experience by a strong acceleration, regenerative breaking and especially a reduced noise level. However, engine vibrations and sound transmit valuable feedback to drivers of conventional cars, e.g. signaling(More)
Due to the release of several electric vehicles (EV) to the car market, the number of sales is expected to increase soon. Concerning in-vehicle information systems (IVIS) of EVs, different kinds of information need to be communicated to the driver. E.g. displayed numbers for current energy consumption or the energy left in the batteries are hereby critical(More)
In this paper we report on our ongoing work to introduce freehand gestures in cars as an alternative input modality. Contactless gestures have hardly been successful in cars so far, but have received attention in other contexts recently. We propose a way to achieve a better acceptance by both drivers and car manufacturers. Using a four-step process, we(More)
Tactile feedback on touch surfaces has shown to greatly improve the interaction in quantitative and qualitative metrics. Recently, researchers have assessed the notion of remote tactile feedback, i.e., the spatial separation of touch input and resulting tactile output on the user’s body. This approach has the potential to simplify the use of tactile(More)
In this paper, we want to follow up the question, how characteristics of electromobility could be represented in the interior of electric vehicles (EV). For that purpose we followed a user-centered approach to collect intuitive and implicit relationships between some descriptive characters of electromobility and real materials. In a study with 13(More)
The importance of User Experience is growing in the automotive context, which differs from other products regarding its safety-criticality. Freehand gestures might be a solution for enhancing the User Experience without endangering road users. This paper proposes some approaches on using freehand gestures to create User Experience in the automotive context(More)
Interactive surfaces form an integral component of intelligent environments. In the paper, we describe HapticArmrest, a simple tactile interface that communicates tactual surface characteristic and form of interactive elements on direct touch surfaces. Spatially separating manual touch input and active tactile output allows for the combination of various(More)
Sustainability is today one of the key factors for car manufacturers worldwide. Electric vehicles (EVs) are clean, quiet and efficient and offer a great opportunity to keep our environment healthy. After the first era of EVs in 1900 (28% of the vehicles in the US were electric at that time [3]) the second era seems to have started: In the US and China one(More)
