  2. 1. The effect of modality on social presence, presence and performance in collaborative virtual environments

    Author : Eva-Lotta Sallnäs; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; collaborative virtual environments; modalities; media richness; social presence; presence; communication media; haptic force feedback; Information technology; Informationsteknik;

    Abstract : Humans rely on all their senses when interacting with others in order to communicate and collaborate efficiently. In mediated interaction the communication channel is more or less constrained, and humans have to cope with the fact that they cannot get all the information that they get in face-to-face interaction.

  4. 2. Preparing Spatial Haptics for Interaction Design

    Author : Jonas Forsslund; Eva-Lotta Sallnäs Pysander; Ylva Fernaeus; Jan Gulliksen; Karl-Johan Lundin-Palmerius; Karon MacLean; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; haptics; interaction design; surgery simulation; haptik; interaktionsdesign; medicinsk simulering; kirurgi; Människa-datorinteraktion; Human-computer Interaction;

    Abstract : Spatial haptics is a fascinating technology with which users can explore and modify3D computer graphics objects with the sense of touch, but its application potentialis often misunderstood. For a large group of application designers it is still unknown,and those who are aware of it often have either too high expectations of what is technicallyachievable or believe it is too complicated to consider at all.

  5. 3. Reflective Spatial Haptic Interaction Design Approaching a Designerly Understanding of Spatial Haptics

    Author : Jonas Forsslund; Eva-Lotta Sallnäs Pysander; Petra Sundström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With a spatial haptic interface device and a suitable haptic rendering algorithm, users can explore and modify virtual geometries in three dimensions with the aid of their haptic (touch) sense. Designers of surgery simulators, anatomy exploration tools and applications that involve assembly of complex objects should consider employing this technology. READ MORE

  6. 4. Design and Evaluation of 3D Multimodal Virtual Environments for Visually Impaired People

    Author : Ying Ying Huang; Yngve Sundblad; Eva-Lotta Sallnäs; Charlotte Magnusson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multimodal interaction; 3D worlds; Haptics; Audio; Visually impaired users; Collaboration; Navigation; Computer science; Datavetenskap;

    Abstract : Spatial information presented visually is not easily accessible to visually impairedusers. Current technologies, such as screen readers, cannot intuitively conveyspatial layout or structure. This lack of overview is an obstacle for a visuallyimpaired user, both when using the computer individually and when collaboratingwith other users. READ MORE

  7. 5. The Influence of Modality Combinations on Communication in Collaborative Virtual Environments

    Author : Jonas Moll; Eva-Lotta Sallnäs-Pysander; Kerstin Severinson Eklundh; Stephen Brewster; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Haptics; Audio; Multimodality; Collaboration; Communication;

    Abstract : Although many studies have been performed on collaboration in multimodal interfaces not many of these have looked specifically on how the supported modalities influence the task solving strategies chosen and the communication between users solving a joint task in collaborative virtual environments. Therefore, the thesis studies performed aimed at shedding light on these aspects of multimodality. READ MORE
