Summary

Uber Medical, a company which owns a proprietary dynamic image correction technology, wanted to help surgeons to develop a surgical video system for their tele-consultations and academic teachings. I mapped the product system architecture, designed the system’s experience and complete set of hardware devices. Other than the products, I defined the brand’s visual identity system.

Main Challenges

Lack of support from product manager
Shattered interactions created by multiple end users

User Touch Points

Collaborative Relation

Commands from Surgeon
Commands from Assistant
Information ( Video / vital signs / status )

Group User’s Experience

Users in a group play different roles in collaborations, they not only interact with their devices but also with other users. The defining of the system architecture began with function charts. I reviewed possible functions all all together then decided what functions should go to which terminal

Main Criteria

High efficiency and smoothness of team collative workflow
Low learning cost

Host Software

Host Hardware

Tablet Hardware

Camera Hardware

Transmitter Hardware

Tablet Software

Task Flow (e.g. tablet software)

This is an example of the tablet’s software interactions. Based on the functional chart, I designed the process of video replaying and editing.

Interactions Between Devices

Controlling Mode

In this mode the host and the tablet work separately. The tablet is held and operated by the filming assistant as a remote controller for monitoring and correcting videos from surgeon’s head camera, while the small screen on the host show basic working status of the entire system

Displaying Mode

When sit the tablet on the dock in the front of the host, the two devices switch to DISPLAYING MODE and begin working together for video review and teleconferencing. The large screen shows surgical videos or meeting participants at the other end, and the small screen shows supplementary information.

A Head Camera

Observation – digging out the needs for design

From my observation and practice in a typical crowded operation room, I found a huge visibility difference between the first and second perspective video taking. I also tried to place a camera in different positions on a surgeon, and finally let the client understand that – they need a head camera

To explore an ideal way to wear a camera on head, I had to take account of both stability and comfortability. I found that the most natural way should be similar with wearing glasses

Stability

A glasses-like frame helps to evenly distribute the camera’s weight on nose, head sides and back

Comfortability

Many surgeons wear their glasses when doing operations. Based on the data gotten from massive measurements, this head camera could be compatible with most glasses shapes

Space Management

The product system consists of five pieces of devices, cables, a charger, and handbooks, which can simply mess up a crowed operating space. Moreover, surgeons sometimes have demands on the product’s portability. So in my spacing design, everything can be packed into a case
