13:04:36 <kaz> meeting: WoT Use Cases
13:04:56 <kaz> present+ Kaz_Ashimura, David_Ezell, Jack_Dickinson, Michael_Lagally
13:06:16 <kaz> regrets+ Michael_McCool
13:06:49 <kaz> present+ Tomoaki_Mizushima
13:09:07 <kaz> scribenick: kaz
13:09:56 <kaz> ml: possibility of Conexxus' participation in Plugfests in the future?
13:10:01 <kaz> de: would think about that
13:10:29 <kaz> ml: maybe we could work on some topic on simulations
13:10:51 <kaz> de: Jack, do you have somebody could help in your mind?
13:10:54 <kaz> jd: yeah
13:11:20 <kaz> ml: simulated behavior like state change
13:11:23 <kaz> ... on and off
13:11:28 <ryuichi> ryuichi has joined #wot-uc
13:11:34 <kaz> ... something like a pump
13:11:44 <kaz> ... handling fluid level
13:12:21 <kaz> de: maybe a group meeting would be helpful
13:12:35 <kaz> ml: next Plugfest would be in March next year
13:12:41 <kaz> de: right time frame for us too
13:13:02 <kaz> i/possibility/topic: Conexxus use cases and plugfest participation/
13:13:24 <kaz> ml: we should talk about the next steps
13:14:07 <kaz> topic: Minutes
13:14:13 <kaz> -> https://www.w3.org/2021/11/23-wot-uc-minutes.html Nov-23
13:14:53 <kaz> ml: (goes through the minutes)
13:15:19 <mlagally> moratorium
13:18:51 <kaz> fixed
13:20:14 <kaz> q+
13:21:04 <kaz> ack k
13:24:08 <kaz> (some discussion on time synchronization)
13:28:48 <kaz> (also about consolidating multiple clock ticks using events, etc.)
13:31:17 <kaz> s/moratorium/typo with "moratorium"/
13:33:31 <kaz> ml: any problems?
13:33:39 <kaz> (none)
13:33:42 <kaz> approved
13:34:08 <kaz> ml: had nice discussion on time series data as well
13:34:26 <kaz> de: first thing wanted to show is the chart
13:34:30 <kaz> ... I showed last time
13:34:37 <kaz> ... [Device comparison]
13:34:57 <kaz> ... first column is IoT Primary devices
13:35:45 <kaz> ... it is important to clarify what the devices, e.g., a camera, do
13:35:53 <kaz> ... and then today's slides
13:36:08 <kaz> ... [WoT and "Pseudo-devices"
13:36:16 <kaz> s/devices"/devices"]/
13:36:40 <kaz> ... fed data from video/audio input streams
13:36:53 <kaz> ... a camera provide video streams
13:37:09 <kaz> ... and smart speakers provide audio streams
13:37:19 <kaz> s/provide v/provide v/
13:38:11 <kaz> ... "pseudo-devices" then substitute computation resources for discrete devices
13:38:28 <kaz> ... client devices understand IoT languages
13:39:46 <kaz> ... security implication of storing the video data on the cloud side
13:39:59 <kaz> ml: camera taking infra-red data possibly
13:40:13 <kaz> ... every certain time period
13:40:24 <kaz> ... that is my image
13:41:08 <kaz> de: we call it (infra-red) heat map
13:41:33 <kaz> ... see the store's layout in different color depending on the temperature
13:41:42 <kaz> ... [Simple Schematic]
13:42:18 <kaz> ... video -stream- processor - WoT Facade- clients
13:42:33 <kaz> ... the ability to reuse the capability
13:43:12 <kaz> ... [TD: Cooler Door]
13:44:01 <kaz> ... [Pseudo-deices in action]
13:44:23 <kaz> ... transport mechanism may be Web Socket or anything
13:45:18 <kaz> ... (connection between Camera and Edge AI Processor)
13:45:35 <kaz> ... the first consume opens the door
13:45:40 <kaz> ... event invoked
13:46:08 <kaz> ... the edge AI get the event
13:46:28 <kaz> ... the POS System only gets the notification
13:49:01 <kaz> ... a lot of legacy devices need upgrade paths
13:49:37 <kaz> ... skimming devices to get credit data, etc.
13:49:57 <kaz> ... flexible AI-based system
13:50:00 <kaz> q?
13:50:18 <kaz> jd: they can leave the existing devices
13:50:26 <kaz> ... based on regulatory, safety, etc.
13:50:35 <kaz> ... might have some push back
13:51:41 <kaz> de: there is a study done on transition to EMV
13:53:13 <kaz> ml: question about the maintenance event
13:53:27 <kaz> ... this is a boolean event
13:53:42 <kaz> ... [TD: Cooler Door]
13:54:01 <kaz> ... any insight about the possible data structure?
13:54:28 <kaz> de: not thinking about the detail, but something like facing one direction or another
13:55:44 <kaz> ml: another question on the sequence diagram
13:55:56 <kaz> ... [Pseudo-devices in action]
13:56:09 <kaz> ... encrypted data connection with the AI processor?
13:56:25 <kaz> de: problem with the API ecosystem
13:56:41 <kaz> ... not all the edge devices don't have HTTPS capability
13:57:20 <kaz> ... the connection here is protected by OAuth2
13:57:27 <kaz> ... also TLS
13:57:51 <kaz> ... this side (AI Processor on the right side) is protected
13:58:56 <kaz> ml: do you have band width to put this idea into a use case?
13:59:07 <kaz> de: need somebody
13:59:14 <kaz> jd: next week?
13:59:24 <kaz> ... will catch up with David
13:59:30 <kaz> ml: aob?
13:59:32 <kaz> (none)
13:59:34 <kaz> [adjourned]
13:59:38 <kaz> rrsagent, make log public
13:59:42 <kaz> rrsagent, draft minutes
13:59:42 <RRSAgent> I have made the request to generate https://www.w3.org/2021/11/30-wot-uc-minutes.html kaz
