Cell-Agent : Structure and Methodology

At its core, the Cell-Agent framework consists of a cutting-edge Multimodal Giant Language Mannequin, the GPT-4V, a textual content detection module used for textual content localization duties. Together with GPT-4V, Cell-Agent additionally employs an icon detection module for icon localization. 

Visible Notion

As talked about earlier, the GPT-4V MLLM delivers passable outcomes for directions and screenshots, but it surely fails to output the placement successfully the place the operations happen. Owing to this limitation, the Cell-Agent framework implementing the GPT-4V mannequin must depend on exterior instruments to help with operation localization, thus facilitating the operations output on the cellular display screen. 

Textual content Localization

The Cell-Agent framework implements a OCR software to detect the place of the corresponding textual content on the display screen at any time when the agent must faucet on a particular textual content displayed on the cellular display screen. There are three distinctive textual content localization eventualities. 

Situation 1: No Specified Textual content Detected

Difficulty: The OCR fails to detect the desired textual content, which can happen in complicated photos or as a consequence of OCR limitations.

Response: Instruct the agent to both:

  • Reselect the textual content for tapping, permitting for a guide correction of the OCR’s oversight, or
  • Select another operation, reminiscent of utilizing a unique enter methodology or performing one other motion related to the duty at hand.

Reasoning: This flexibility is critical to handle the occasional inaccuracies or hallucinations of GPT-4V, guaranteeing the agent can nonetheless proceed successfully.

Situation 2: Single Occasion of Specified Textual content Detected

Operation: Routinely generate an motion to click on on the middle coordinates of the detected textual content field.

Justification: With just one occasion detected, the probability of appropriate identification is excessive, making it environment friendly to proceed with a direct motion.

Situation 3: A number of Situations of Specified Textual content Detected

Evaluation: First, consider the variety of detected situations:

Many Situations: Signifies a display screen cluttered with comparable content material, complicating the choice course of.

Motion: Request the agent to reselect the textual content, aiming to refine the choice or regulate the search parameters.

Few Situations: A manageable variety of detections permits for a extra nuanced method.

Motion: Crop the areas round these situations, increasing the textual content detection bins outward to seize further context. This enlargement ensures that extra data is preserved, aiding in decision-making.

Subsequent Step: Draw detection bins on the cropped photos and current them to the agent. This visible help helps the agent in deciding which occasion to work together with, primarily based on contextual clues or process necessities.

This structured method optimizes the interplay between OCR outcomes and agent operations, enhancing the system’s reliability and adaptableness in dealing with text-based duties throughout varied eventualities. The whole course of is demonstrated within the following picture.

Icon Localization

The Cell-Agent framework implements an icon detection software to find the place of an icon when the agent must click on on it on the cellular display screen. To be extra particular, the framework first requests the agent to offer particular attributes of the picture together with form and colour, after which the framework implements the Grounding DINO methodology with the immediate icon to establish all of the icons contained inside the screenshot. Lastly, Cell-Agent employs the CLIP framework to calculate the similarity between the outline of the clicking area, and calculates the similarity between the deleted icons, and selects the area with the very best similarity for a click on. 

Instruction Execution

To translate the actions into operations on the display screen by the brokers, the Cell-Agent framework defines 8 completely different operations. 

  • Launch Software (App Title): Provoke the designated software from the desktop interface.
  • Faucet on Textual content (Textual content Label): Work together with the display screen portion displaying the label “Textual content Label”.
  • Work together with Icon (Icon Description, Location): Goal and faucet the desired icon space, the place “Icon Description” particulars attributes like colour and form of the icon. Select “Location” from choices reminiscent of prime, backside, left, proper, or heart, presumably combining two for exact navigation and to cut back errors.
  • Enter Textual content (Enter Textual content): Enter the given “Enter Textual content” into the energetic textual content area.
  • Scroll Up & Down: Navigate upwards or downwards by means of the content material of the current web page.
  • Go Again: Revert to the beforehand seen web page.
  • Shut: Navigate again to the desktop immediately from the present display screen.
  • Halt: Conclude the operation as soon as the duty is completed.


Each step of the operation is executed iteratively by the framework, and earlier than the start of every iteration, the person is required to offer an enter instruction, and the Cell-Agent mannequin makes use of the instruction to generate a system immediate for your complete course of. Moreover, earlier than the beginning of each iteration, the framework captures a screenshot and feeds it to the agent. The agent then observes the screenshot, operation historical past, and system prompts to output the subsequent step of the operations. 


Throughout its operations, the agent would possibly face errors that forestall it from efficiently executing a command. To reinforce the instruction achievement price, a self-evaluation method has been applied, activating beneath two particular circumstances. Initially, if the agent executes a flawed or invalid motion that halts progress, reminiscent of when it acknowledges the screenshot stays unchanged post-operation or shows an incorrect web page, it will likely be directed to contemplate different actions or regulate the prevailing operation’s parameters. Secondly, the agent would possibly miss some parts of a fancy directive. As soon as the agent has executed a sequence of actions primarily based on its preliminary plan, it will likely be prompted to evaluate its motion sequence, the most recent screenshot, and the person’s directive to evaluate whether or not the duty has been accomplished. If discrepancies are discovered, the agent is tasked to autonomously generate new actions to meet the directive.

Cell-Agent : Experiments and Outcomes

To judge its skills comprehensively, the Cell-Agent framework introduces the Cell-Eval benchmark consisting of 10 generally used functions, and designs three directions for every software. The primary operation is easy, and solely covers primary software operations whereas the second operation is a little more complicated than the primary because it has some further necessities. Lastly, the third operation is probably the most complicated of all of them because it accommodates summary person instruction with the person not explicitly specifying which app to make use of or what operation to carry out. 

Transferring alongside, to evaluate the efficiency from completely different views, the Cell-Agent framework designs and implements 4 completely different metrics. 

  • Su or Success: If the mobile-agent completes the directions, it’s thought-about to be successful. 
  • Course of Rating or PS: The Course of Rating metric measures the accuracy of every step through the execution of the person directions, and it’s calculated by dividing the variety of appropriate steps by the whole variety of steps. 
  • Relative Effectivity or RE: The relative effectivity rating is a ratio or comparability between the variety of steps it takes a human to carry out the instruction manually, and the variety of steps it takes the agent to execute the identical instruction. 
  • Completion Charge or CR: The completion price metric divides the variety of human-operated steps that the framework completes efficiently with the whole variety of steps taken by a human to finish the instruction. The worth of CR is 1 when the agent completes the instruction efficiently. 

The outcomes are demonstrated within the following determine. 

Initially, for the three given duties, the Cell-Agent attained completion charges of 91%, 82%, and 82%, respectively. Whereas not all duties have been executed flawlessly, the achievement charges for every class of process surpassed 90%. Moreover, the PS metric reveals that the Cell-Agent constantly demonstrates a excessive probability of executing correct actions for the three duties, with success charges round 80%. Moreover, in accordance with the RE metric, the Cell-Agent reveals an 80% effectivity in performing operations at a degree similar to human optimality. These outcomes collectively underscore the Cell-Agent’s proficiency as a cellular gadget assistant.
