User Instruction
This page is an instruction about how to use our system.
You need to have a HoloLens in the first place :). We assume our target users are already familiar with the basic interactions(gestures, gaze) with HoloLens. If you are not, please check these out!
After you get used to using HoloLens, you can open our app in start menu.
Please wait for it to load the first time you use it. It won't take long. Once the loading is finished, you'll see a main menu with 2 buttons in front of you: Zoom and Subtitle
Click 'Zoom' button on main menu, you will see a square frame with some text prompt. Now you can use both hands to resize the frame.
Move your head to locate the curser on anything you would like to magnify, then click on the frame to take a picture. You can use both hands to zoom in and zoom out. You can also drag the image window to somewhere else you like and it will keep facing you, which is convenient for use cases like note taking.
If you want to retake a picture, click 'Retry' button, and you can do the above again; if you want to quit, click 'Menu' button.
Click 'Subtitle' button on main menu, you will see a semi-transparent text box in front of you, around which you can also see some text prompts about Subtitle. When you talk to another person, the system will transcribe what you say into text and display it in the box. You can use the slider to adjust the font size.
Similarly, if you want to quit, click 'Menu' button.
For Zoom:
- Our system currently only supports magnifying ONE image at a time. If you retake the image, images you took previously would disappear.
- Taking images may take several seconds, we appreciate your patience :)
- Please zoom-in an area where it has decent lighting in order to avoid long camera exposure time which could lead to a blurring image.
- If the frame is over the camera viewpoint, the photo would not be taken. Thus, please scale it down and retake the photo.
- Due to the constraint of the Hololens, please do your gesture slowly in order to make sure the camera has detected your command.
For Subtitle:
- Our system currently supports 1-on-1 conversation ONLY. The performance is not guaranteed in conversation scenarios other than that.
- Please avoid two people speaking simultaneously, which may cause confusion. We may support that functionalities in our further releases.
