“…Signal perception, usually vibrotactile and on the fingertips, has been examined as a function of intensity [19], duration [44], and tempo and rhythm [12,44]. Information can be expressively conveyed through tactile patterns [5], but at least small numbers of arbitrary mappings can be learned as easily as meaningful ones [11]. Systematic techniques are essential for larger sets [5,44].…”

“…Information can be expressively conveyed through tactile patterns [5], but at least small numbers of arbitrary mappings can be learned as easily as meaningful ones [11]. Systematic techniques are essential for larger sets [5,44]. For small sets, ad hoc creation with iterative testing and refinement [43] is suitable and is the approach taken here, though the diverse range of users in the presentation setting brings special challenges.…”

“…Nevertheless, most seemed to easily find adequate mnemonics based on a combination of order and signal characteristics; the current signal mapping alone was not generally enough. However, humans can process tactile information while under high cognitive load [5,43], and with training, are able to parse haptic signals more proficiently [45]. Also, the variety of signals preferred by 14 users suggests that personalized cues may allow for more intuitive processing.…”

To moderate oral presentations a chair must manage time, and communicate time parameters to speakers through a variety of means. But speakers often miss time cues, chairs cannot confirm their receipt, and the broken dialogue can be a sideshow for the audience. We developed HaNS, a wireless wrist-worn chair-speaker Haptic Notification System that delivers tactile cues for time-managing oral presentations, and performed field observations at university research seminars and two mid-sized academic conferences (input from 66 speakers, 21 chairs, and 65 audience members). Results indicate that HaNS can improve a user's awareness of time, facilitate chair-speaker coordination, and reduce distraction of speaker and audience through its private communication channel. Eliminating overruns will require improvement in speaker 'internal' control, which our results suggest HaNS can also support given practice. We conclude with design guidelines for both conference-deployed and personal timing tools, using touch or another notification modality.

“…In receiver-based floor control, all participants in a meeting transmit their signal, however, receivers only process the signal of the participant who has the floor and, in sender-based floor control, only the signal of the participant who has the floor is transmitted [10]. Management of the floor can either be by a moderator or automatically using a mechanism such as a turn taking protocol [5]. Furthermore, mechanisms like hand raising can be used in order to request access to the floor [15].…”

“…There are a number of commercial Web meeting conferencing systems available, such as GoToMeeting 1 , Adobe Connect 2 , BeamYourScreen 3 , WebEx Meeting Center 4 and GoMeetNow 5 . While these commercial tools may work well in environments with large amounts of available bandwidth, they are not necessarily suitable for the type of Internet connectivity that typically exists in Africa and developing countries.…”

Online meetings allow for remote conferencing and collaborative work among geographically dispersed participants and can save time and expenses that an ordinary face-toface meeting would require. However, carrying real-time communication within the packet-switched Internet is a challenging task, especially in an African context, which is characterized by low bandwidth and unstable Internet connections. This paper presents and evaluates a tool that was designed to enhance the user experience for Webbased conferencing, given the constraints of Internet conditions typical of Africa. Approaches used to achieve this goal included: reprioritisation of multimedia streams, image differentiation, half duplex communication mode and stream compression. It was found that less than 56 kbps of bandwidth was required in order to: transmit audio; use video to convey presence; share slides and screen; and support text-based chat and floor control. Furthermore, users were largely satisfied with the tool and felt that it created a good user experience.
