7 Specification for a show of hands tool
8 draft-duke-shmoo-show-of-hands-00
10 Abstract
12 This is the specification for an experimental show of hands tool for
13 the Meetecho system to be used in online meetings to help chairs
14 quickly poll the meeting. This tool is different from the previous
15 experimental virtual hum tool as it addresses a different use case
16 with different functionality. Following mixed feedback in the IETF
17 108 post-meeting survey, the experimental virtual hum tool has been
18 withdrawn from the Meetecho client for IETF 109.

69 1. Introduction
71 This is the specification for an experimental show of hands tool for
72 the Meetecho system to be used in online meetings to help chairs
73 quickly poll the meeting. This tool is different from the previous
74 experimental virtual hum tool [DRAFT_VIRTUAL_HUM] as it addresses a
75 different use case with different functionality. Following mixed
76 feedback in the IETF 108 post-meeting survey [SURVEY_108], the
77 experimental virtual hum tool has been withdrawn from the Meetecho
78 client for IETF 109.
80 2. Definition and usage of "show of hands"
82 In the context of this document, a "show of hands" is a simple, fast
83 and anonymous mechanism for asking a yes/no question of a large group
84 of people, with the common understanding that this mechanism is not a
85 means for calling consensus and therefore only minimal formality of
86 process is required.
88 3. Tool specification
90 This specification is intended to be feature complete, which means
91 that what should be implemented is only what is explicitly stated
92 here and nothing else.
94 3.1. General
96 * There is only one type of show of hands
98 * Only one show of hands can be open at any one time in a session.
100 * The Secretariat are excluded from the show of hands and are not
101 able to participate and do not feature in the calculations:
103 3.2. Opening and closing show of hands
105 * A session chair can open a show of hands.
107 * A session chair can assign a title to a show of hands to be made
108 visible to session participants.
110 * A session chair can open a show of hands at any time during a
111 session, except when a show of hands is already open.
113 * A session chair can open multiple shows of hands per session.
115 * A show of hands is closed when the session chair closes it.
117 3.3. Taking part in a show of hands
119 * While a show of hands is open an indicator needs to be shown to
120 all participants that includes the title, if assigned, and either
121 the options below or a link that goes directly to them.
123 * When a show of hands is open each participant in the session may
124 take part through the following mechanism: Each participant is
125 presented with the following options from which they can select
126 one. None of the options is selected as a default. "Raise hand"
127 "Do not raise hand" No confirmation action is required. A
128 participant can change their chosen option at any time while the
129 show of hands is open.
131 * When a participant selects any option then they are considered to
132 have participated in the show of hands.
134 * If a participant joins the session during the show of hands then
135 they can take part.
137 * If a participant leaves the session during the show of hands and
138 they are considered to have participated then their show of hands
139 is still used for data calculation.
141 3.4. Calculating and displaying the result
143 * In real time during a show of hands the following data is
144 calculated: The total number of participants who selected the
145 "Raise hand" option. The total number of participants who
146 selected the "Do not raise hand" option The total number of
147 participants who have not selected either option.
149 * All totals are displayed to all participants in real time.
151 * When the show of hands is closed the totals are left displayed
152 along with the relevant title.
154 * When a new show of hands is opened the totals from the previous
155 show of hands are still shown, along with their assigned titles,
156 in an ordered list.
158 3.5. Implementation notes
160 * The way in which the options are presented and selected and the
161 way in which the totals are presented are left to the implementer.
162 However, the text for each option should appear as above.
164 4. Alternative approaches
166 The following alternative approaches were considered.
168 4.1. Multiple options
170 Consideration was given to allowing more options (e.g., thumbs up,
171 neutral, and thumbs down) and to allowing the chair to specify the
172 list of options to be used in a show of hands. These alternatives
173 may increase the use cases of the tool but also may increase its
174 complexity. At this stage these alternatives have not been included,
175 nor have they been ruled out.
177 5. Security Considerations
179 Meetecho participation is restricted to people who have datatracker
180 accounts, providing some assurance of identity. Potential attacks
181 against this tool will either subvert Meetecho admission control, or
182 involve multiple datatracker registrations (and Meetecho logins) to
183 amplify the voice of a single individual.
185 The integrity of this tool is dependent on the integrity of the
186 registration and fee waiver processes. In particular, they must weed
187 out duplicate registrations, bots, and so on.
189 6. IANA Considerations
191 This document has no IANA actions.
