Conference Paper
Full-text available
Current virtual and augmented reality head-mounted displays usually include no or only a single vibration motor for haptic feedback and do not use it for guidance. We present HapticHead, a system utilizing multiple vibrotactile actuators distributed in three concentric ellipses around the head for intuitive haptic guidance through moving tactile cu...
Conference Paper
Full-text available
A high level of presence is an important aspect of immersive virtual reality applications. However, presence is difficult to achieve as it depends on the individual user, immersion capabilities of the system (visual, auditory, and tactile) and the concrete application. We use a vibrotactile grid around the head in order to further increase the leve...
Conference Paper
Full-text available
Creating tactile patterns for a grid or a 3D arrangement of a large number of actuators presents a challenge as the design space is huge. This paper explores two different possibilities of implementing an easy-to-use interface for tactile pattern design on a large number of actuators around the head. Two user studies were conducted in order to iter...
Chapter
Full-text available
Creating tactile patterns on the body via a spatial arrangement of many tactile actuators offers many opportunities and presents a challenge, as the design space is enormous. This paper presents a VR interface that enables designers to rapidly prototype complex tactile interfaces. It allows for painting strokes on a modeled body part and translates...
Article
Full-text available
Tactile patterns are a means to convey navigation instructions to pedestrians and are especially helpful for people with visual impairments. This article presents a concept to provide precise micro-navigation instructions through a tactile around-the-head display. Our system presents four tactile patterns for fundamental navigation instructions in...
Conference Paper
Tactile patterns are a means to convey general direction information to pedestrians (for example when turning right) and specific navigation instructions (for example when approaching the stairs). Tactile patterns are especially helpful for people with visual impairments in navigation scenarios and can also be used to deliver general notifications....
Conference Paper
Current generation virtual reality (VR) and augmented reality (AR) head-mounted displays (HMDs) usually include no or only a single vibration motor for haptic feedback and do not use it for guidance. In a previous work, we presented HapticHead, a potentially mobile system utilizing vibration motors distributed in three concentric ellipses around th...
Conference Paper
In mobile contexts guidance towards objects is usually done through the visual channel. Sometimes this channel is overloaded or not appropriate. A practicable form of haptic feedback is challenging. Electrical muscle stimulation (EMS) can generate mobile force feedback but has a number of drawbacks. For complex movements several muscles need to be...
Conference Paper
Current generation virtual reality (VR) and augmented reality (AR) head-mounted displays (HMDs) usually include no or only a single vibration motor for haptic feedback and do not use it for guidance. We present HapticHead, a system utilizing 20 vibration motors distributed in three concentric ellipses around the head to give intuitive haptic guidan...
