We have designed and evaluated Nautilus -- a group game played in interactive virtual space. This was a study about new kinds of computer games with new types of user interfaces. Our aim was to reduce the boundaries between the surrounding physical space and the virtual space designed to appeal to users' senses. We utilized the iterative Human-Centred(More)
Traditionally computer games are played with a keyboard and a mouse or a joystick. The playing relies mainly on visual and auditory senses. Tactile or haptic user interfaces and natural movements of the human being, e.g. running, are seldom utilised in computer games. The Lumetila project (Virtual Space – User Interfaces of the Future) aims at developing a(More)
Children develop important skills at playgrounds. Physical play promotes health and reacting to other children establishes social behavior patterns. By augmenting playground elements with sensor technology, video displays, and computer software, we pursued to take the experience further. This paper describes what was achieved; UbiPlay, a technology platform(More)
Industrial maintenance is a complex and knowledge-intensive field. Therefore, maintenance technicians need to have easy access to versatile and situationally relevant knowledge. The aim of this paper is to increase the understanding of maintenance technicians' interactions and knowledge sharing with colleagues and technology during maintenance work. Three(More)
The military environment is changing, e.g., the operating environment is becoming more varied and demanding. Due to these challenges, new user interfaces (UIs) are required providing improved soldier protection and performance both in daytime and night-time conditions. The new UIs should, e.g., improve the soldier' s situation awareness, i.e., perception of(More)
