Finding ways to innovate on the design & usage of Bodycams for law enforcement.

Erik Soriano University of Miami

Problem Statement

EXAMPLE IMAGE:

HOW MIGHT WE Improve the UX of touchscreen Bodycams for law enforcement officers (LEOs) when operating the device in their daily work, by utilizing more hands-free approach such as automated features (AI) and voice commands while saving valuable time. §

Ensure officers spend less time trying to active/deactivate software to focus on critical issues

§

Explore ways in which AI can help officers when they need help (situational awareness)

§

Emphasis on visual hierarchy so that officers can adjust settings, and access key features as easily as possible

§

Focus on only showing the options that most LEOs use most, while offering secondary features in an easy-to-access way, for other tasks that officers need

§

Maximize screen real estate without adding too many options that distract the user

Bodycams: Overview Body-worn cameras or ‘Bodycams’ are special gadgets used by public safety teams (such as Police force, and firefighters.) to assist them when performing their daily duties that require open contact and interaction with public citizens. They are cameras with at least one microphone and internal data storage and allow audio/video footage to be stored and analyzed with compatible software. The cameras are typically located on the police officer’s chest or head. There are many mixed opinions about Bodycams, regarding their benefits and tradeoffs, and ethical aspects.

Project Scope OBJECTIVES: 1.

Redesign a touchscreen BodyCam with emphasis on UI visual hierarchy and ease of use

2.

Ensure the proposed redesign prioritizes safety and maintains key features that LEOs need (i.e., video/audio capture, notifications, data entry, data sync)

3.

Explore new ways to present notification messages

4.

Explore how AI (automation) or voice commands can save time for officers during crucial moments 1.

Delegate data sync, cam/audio record automatically with situational awareness to the device

2.

Have sensors for an officer’s vital signs, etc.

5.

Create a working prototype that can be used for usability testing with LEOs

6.

Deliverables will include, low-fi, hi-fi prototypes and wireframes, a design language (e.g., fonts, icons, colors, etc.)

OTHER CONSIDERATIONS:

WHAT

FOR WHOM

Redesign and Innovate on the experience of using Bodycams in day-to-day workflow while saving time

For Law Enforcement Officers; while considering their safety and the safety of the public they interact with

CONTEXT

Keeping in mind: how often they deal with difficult situations; how tech savvy they are; what their typical day of work entails; How the device should react when an officer is down

GOALS

We aim to improve and UX and save time for officers to spend less time trying to use the device and more time performing their duties

Time of use for the device (Nighttime/Daytime) • Consider Incorporating automatic (but optional) Light/Dark UI to adjust on real-time clock Police attire and accessories: • Wears polarized sunglasses; gloves When an officer is down/or other emergencies: • Notify troops in the area, as well as agency • Sound an alarm to alert others around of danger

THE CRUX

We have to figure out the current pain points/and successful UX moments that LEOs face when using Body-worn cameras. Learn their feelings/opinions toward using Bodycams. Which features they use most/least.

Bodycams: Stats 47%

Of General-purpose law enforcement use Bodycams in their daily duties /performance

49%

Of bodycams are used alone by Sheriff’s offices

60%

Local police officers use Bodycams in their daily duties/performance

60+

Different body-worn cameras are produced SPECIFICALLY for law enforcement

85%

Of the public expects the same level of service and speed from gov’t as they do from retail/consumer experiences

86%

General purpose law enforcement had PRIOR formal bodycam training

80%

Large police departments use bodycams because of: •

Improve officer safety

•

Increase evidence quality

•

Reduce civilian complaints

•

Reduce liability

Agencies not using stated: •

Cost

•

Video storage

•

System maintenance

Bodycams: Requirements VIDEO REQUIREMENTS • • • • •

Recording Format: standard open (e.g., MP4, MKD) can be opened without processing or conversion Video Resolution: HD; 720P; 1080P HD, 30FPS (if H.264 conversion) Compression: lowest possible (to optimize storage and depends on type of analysis needed) (e.g., MPEG-4, H2.64) Record trigger: continuously or user-trigger, event-trigger (motion, speech, etc) Cam Focus: should be able to focus from 1ft away to infinity; autofocus and fixed focus for usability • AVOID manual settings as to not distract user • CONSIDER automatic image stabilization to reduce blur and jitter

DATA SYNC/TRANSFER • •

•

DEVICE REQUIREMENTS •

AUDIO REQUIREMENTS • • •

Audio quality: clear record of conversational speech at distance of 3 ft w/o too much background noise Audio resolution: 4-60MB, if high speech quality then 22kHz; MP3 format preferred Record trigger: continuously or user-trigger, event-trigger (motion, speech, etc)

Data transfer: USB2/USB3 port for changing and data transfer Data export in original unaltered form • Include serial no.

• Device info • Device events (on/off/charging) • Remaining storage capacity, etc./ Simultaneous Sync: can record audio/video sync • Automatically gather data such as: • Date/time (synced with real world) • Info about wearer • Location

•

•

Battery: should last a full shift by office (8-12) hours. Devices w/o rechargeable batteries NOT recommended Durability: should withstand the following: • Repetitive pressure • Vibration • Mechanical shock • Extreme temperatures (COLD/VERY HOT) • Resistant to hazards (dust, condensation, water splash, RF interference) Weight: should not distract or hinder officer wearing device from performing job functions, should have varying mounting methods
